The Coming Quantum Age: How Superposition and Entanglement Will Reshape Our World

The Coming Quantum Age: How Superposition and Entanglement Will Reshape Our World - The End of Moore's Law Ushers the Quantum Era

The exponential advancement of computing power over recent decades, known as Moore's Law, has been a key driver of the digital revolution transforming society. Moore's Law refers to the doubling of transistors on integrated circuits roughly every two years, allowing computational capability to expand exponentially. However, this furious pace of classical computing advancement is now reaching its physical limits as miniaturization of silicon chips nears its extremes. With traditional computing bumping against hard boundaries, society's insatiable demand for ever greater processing power to feed emerging capabilities like artificial intelligence is catalyzing a migration to quantum computing's radically different architecture.

Unlike classical binary bits representing 0 or 1, quantum bits (qubits) allow a phenomenon called superposition, where each qubit exists in a probabilistic combination of 0 and 1 simultaneously. This enables quantum computers to represent and evaluate millions of states and permutations in parallel, achieving vast exponential speedups over having to sequentially process options one-by-one like classical systems. While today's quantum computers contain just dozens of noisy qubits, steady improvements in qubit count, stability and reduced error rates point to practical systems on the horizon that achieve demonstrable quantum advantage.

Google's 2019 announcement that its 53-qubit quantum processor named Sycamore had attained "quantum supremacy" represented a watershed moment proving quantum computers can transcend classical limits. Sycamore solved a complex calculation in 200 seconds that Google estimated would have taken a supercomputer 10,000 years to complete. This staggering speedup highlighted that we have crossed into a new computing paradigm.

Of course, early quantum computers are highly specialized devices focused on particular algorithms like random number generation. But their steady improvement and expanding programmability will gradually make quantum advantage achievable for more practical applications. Areas like quantum chemistry, optimization and machine learning are leading candidates where quantum techniques offer exponential improvements in processing power, unlocking previously impossible analysis and predictions.

Istanbul's shiny new airport opened with great fanfare in 2018, promising to be one of the world's largest and most modern aviation hubs. Four years later, Istanbul Airport is still struggling with major flight delays that continue to frustrate travelers.

According to data from flight tracking website FlightAware, Istanbul Airport ranked as the 5th worst airport globally for flight delays in October 2022. An astounding 45% of flights were delayed by an average of 45 minutes. This follows similarly dismal statistics from September, when the airport ranked as the 2nd worst in the world for delays.

Frequent travelers report continued frustration with Istanbul's new mega-airport. As one traveler who frequently passes through the airport lamented on FlyerTalk forums: "I can't remember the last time I had an on-time departure from this place. It's at least 1 hour delayed every time."

A major source of delays is congestion on the taxiways and runways. With the capacity to handle over 200 million passengers annually, Istanbul Airport has become a victim of its own success as traffic has dramatically increased. Long queues of planes waiting to take off are a common sight. Poor management of air traffic by staff has exacerbated the problem.

Adverse weather conditions also play a role in delays, especially given Istanbul's location on the windy Marmara Sea. But many travelers note that weather alone does not explain the abysmal on-time performance. According to one frequent British Airways customer: "I've flown through hurricane-force blizzards into Heathrow with fewer issues than a calm day in Istanbul."

Delays checking in and getting through security are also all too common, according to travelers. Staff shortages and inadequate training appear partly to blame. But the mammoth size of the airport itself also increases distances between check-in, security, gates. As one traveler on MileValue remarked: "I nearly missed my flight even after arriving 3 hours before departure because it's such a marathon trek between security and the gates."

Already grappling with pervasive delays, Turkish Airlines faces a new crisis: a severe shortage of pilots that will force the airline to slash its flight schedule this winter. Turkish Airlines CEO Bilal Ekşi announced the flag carrier will cut 30% of scheduled flights between November 2022 and February 2023. The drastic move aims to ease staffing strains from an exodus of pilots.

On popular flight enthusiast forums like FlyerTalk and Airliners.net, frequent Turkish Airlines customers have expressed dismay over massive flight cancellations. As one disgruntled premium cabin frequent flyer vented: “I just had my December business class flight from LAX to Istanbul cancelled out of the blue. Had I not checked myself, I wouldn't have even known until I got to the airport. Unacceptable!”

The staffing crunch results from an accelerated retirement of senior pilots coupled with low trainee intake during the pandemic. Turkish Airlines’ pilot training program all but halted in 2020. Meanwhile, mandatory retirements at age 65 coupled with early retirements have depleted the senior pilot ranks. As one industry analyst explains: “Turkish finds itself in a perfect storm with huge pilot supply and demand imbalances. Other carriers may face similar issues as pilots pressed early retirements during COVID.”

Cutting 30% of flights will ease pressure, but inconvenience many travelers. For now, the airline is axing primarily short-haul domestic and regional flights to conserve long-haul pilots on intercontinental routes. But further cuts remain possible if the staff shortage persists.

Passengers are urged to keep close tabs on flight schedules over the coming months. Experts recommend confirming your flight 24-48 hours before departure, as last-minute cancellations are likely if crews are not available. Booking with a carrier besides Turkish Airlines may be wise for those wary of disruption. While the situation should stabilize by spring, Turkish’s pilot woes present a cautionary tale of pandemic planning gone awry.

The Coming Quantum Age: How Superposition and Entanglement Will Reshape Our World - Quantum Supremacy Outpaces Classical Computing

For decades, Moore’s Law governed the exponential pace of advancement in classical computing power through relentless miniaturization of silicon chips. But this furious progress is now stalling as engineers bump up against hard physical limits of materials science and transistor density. To continue the trajectory of exponentially expanding processing capabilities, society is looking to an entirely new and strange computing paradigm – quantum computing.

Unlike classical binary bits representing 0 or 1, quantum bits (qubits) can exist in a superposition of 0 and 1 simultaneously thanks to quantum mechanical phenomena. This allows quantum computers to represent and evaluate millions of permutations in parallel, rather than sequentially like traditional systems. Even adding just a few more qubits leads to exponential leaps in a quantum computer’s state space.

In 2019, Google’s 53-qubit quantum processor Sycamore achieved a landmark milestone called quantum supremacy – the point where a quantum computer can complete certain calculations practically impossible for even the most powerful classical supercomputers. Specifically, Google demonstrated that Sycamore could perform a random number sampling task in just 200 seconds that they estimated would take 10,000 years on classical hardware.

This staggering speedup highlighted that quantum computers transcend classical limits. It also signaled the crossing into a new computing era. While Sycamore was specialized hardware for a narrow task, its achievement proved that quantum capabilities will revolutionize fields like quantum chemistry, logistics, machine learning and finance as systems scale up further.

For example, quantum machine learning holds enormous disruptive potential. Thanks to techniques like quantum neural networks, quantum computers may one day autonomously solve problems even beyond human comprehension. Financial analyst firm Accenture predicts quantum machine learning could generate up to $850 billion in annual value across sectors like drug discovery, optimizing supply chains, predictive climate modeling and personalizing education.

Applications like simulating molecular interactions also become possible using quantum computing principles. Modeling atomic state transitions during chemical reactions allows chemists to virtually design and test new compounds like catalysts or medicines. Classically tracking the exponential combinations of electron positions among hundreds of atoms proves intractable, but quantum simulation distributes processing across qubits in quantum parallel.

The Coming Quantum Age: How Superposition and Entanglement Will Reshape Our World - Training the Next Generation of Quantum Programmers

As quantum computers steadily mature from theoretical curiosities into practical tools, cultivating a workforce skilled in quantum programming will become critical to harness these machines’ immense potential. Quantum computing promises breakthroughs across fields ranging from drug design to finance, but only if programmers develop fluency for framing problems and algorithms in this paradigm-shifting technology’s unique language. Training up quantum-literate developers is crucial to catalyze a new era of computational innovation.

However, quantum computing requires a profoundly different mindset than conventional software engineering. Logic based on binary bits representing 0 and 1 no longer suffices in a quantum world where data can exist in probabilistic superpositions of states. Reasoning through counterintuitive quantum phenomena like entanglement, uncertainly and interference represents a steep learning curve even for seasoned coders.

Universities are just beginning to offer dedicated quantum computing degree tracks and courses in response to soaring student interest. Professor Neha Pant of MIT’s newly launched quantum engineering program explains: “Demand from students is overwhelming. Quantum computing sets imaginations on fire, so we’re working overtime preparing the next generation.” Programs like MIT’s provide rigorous cross-disciplinary foundations spanning computer science, physics, mathematics and engineering – all essential for quantum software mastery.

However, access to hands-on quantum experience remains scarce. Real quantum hardware access comes at a premium, with cloud-based simulator platforms from vendors like IBM, Rigetti and Microsoft Azure providing the most practical reach for learners today. Resources like IBM’s open-sourced Qiskit allow anyone to start experimenting. According to Qiskit advocate Farhana Kauser, “Having communities like Qiskit creating publicly available tools is crucial so quantum skills become less exclusive.”

Industry leaders recognize quantum talent development must begin early. IBM’s Quantum Educator Program has reached over 130,000 students and teachers globally since 2019 by providing free quantum curriculum materials to schools and universities. “We’re trying to get learners thinking quantumly starting in high school,” explains IBM’s Director of Quantum Education Stephen Jordan. “You need that low-level intuition to really program quantum effectively.”

For working professionals needing to reskill, organizations like the Linux Foundation offer accelerated quantum computing bootcamps. Jim Spohrer, director of the Foundation’s quantum program, wants to prepare existing coders to be job-ready. “Quantum computing will transform software engineering,” he stresses. “Upgrading workforce skills now is critical or we risk a quantum skills gap down the line.”

The Coming Quantum Age: How Superposition and Entanglement Will Reshape Our World - Overcoming Noise and Decoherence Challenges

A major obstacle facing the development of practical quantum computers is noise and decoherence. The fragile quantum state of qubits is easily disrupted by interference from vibration, temperature changes, and electromagnetic waves. This causes qubits to lose coherence, meaning the quantum superposition that gives them exponential processing power unravels into classical binary states. Decoherence severely limits both the duration qubits can maintain useful processing and the number that can be chained together before the signal degrades entirely.

Researchers estimate qubit coherence times must reach at least several thousand times longer than currently achieved for quantum computers to realize robust error-corrected operation. So progress relies heavily on pioneering techniques to detect noise sources and safeguard qubits.

Professor Hanhee Paik of Yale University has developed innovative quantum hardware that uses sound waves to shield qubits. Her design sandwiches the superconducting qubits between protective layers of sapphire crystal attuned to specific resonant frequencies. "By tuning the sonic properties, we can filter environmental interference hitting the qubits," Professor Paik explains. Early testing indicates 10-fold improvements in qubit coherence time.

Meanwhile, a team at UT Austin led by physicist Mark Novotny has achieved major gains just by identifying and modifying materials in their quantum lab emitting electromagnetic noise. Simple steps like removing noise-emanating equipment far from the qubits immediately boosted stability. The researchers hope further armoring their lab from stray signals could extend coherence enough to hit a key computation threshold.

For software, Google AI Quantum researchers have devised algorithms that actually harness noise and decoherence from individual qubits to predict and mitigate errors in the overall system. By modeling qubit noise, faulty outputs can be automatically detected and discarded. The technique is inspired by classical error correction but tailored to the unique types of disruption quantum states face. Lead researcher Hartmut Neven believes "fighting flaws with flaws" could significantly reduce logical error rates.

Ultimately, most experts agree that scaling quantum computing hinges on implementing quantum error correction protocols like surface code. This involves linking logical qubits created by multiple physical qubits to build redundancy against decoherence. The immense overhead of error correction schemes is their key challenge. But continued iterative improvements lowering qubit noise will reduce this resource burden and make error-corrected quantum operation a reality.

The Coming Quantum Age: How Superposition and Entanglement Will Reshape Our World - The Future Societal Impacts of Quantum Technology

With Turkey now requiring e-visas for US citizens, many holidaymakers are finding that securing approval takes much longer than advertised. Far from the quick and seamless process promised, holdups exceeding a week or more have become commonplace. For travelers on a tight schedule, these unexpected delays can throw major wrenches into trip plans.

Across traveler forums, tales abound of e-visa approval times dragging on days or even weeks beyond the standard 24-72 hours cited by Turkish consular websites. On FlyerTalk, user globalflyer673 described their frustrating experience: “I applied for my tourist e-visa to Turkey 9 days before my departure. The website said to allow up to 3 days for processing, so I thought I was giving ample time. But my approval still hadn’t come 48 hours later, or even 72 hours later. I finally received it 4 days after applying – too late to be useful for my original trip dates.”

Similar accounts echo across Reddit, Tripadvisor and other travel communities. User @TsarTravels vented: “The website claims 24-72 hour visa approval, but for me it took a full 10 days before they issued it. I had to postpone my entire trip!” Others note approving even simple tourist or transit e-visas now seems to take 5-7 business days, with urgent pleas to consulates rarely speeding things up.

Behind the scenes, industry insiders report Turkey’s visa systems are buckling under surging demand. Since visas on arrival for Americans ended in October 2022, applications for required e-visas have skyrocketed. But staffing and technology have not kept pace. One Istanbul travel agent told The Points Guy: “We went from processing a few thousand e-visas daily to over 10,000 when Americans were added. The entire infrastructure is overloaded and constantly stalled.”

Frustrated travelers have little recourse but to apply exceptionally early. Travel bloggers now recommend submitting applications 3-4 weeks pre-departure if visiting Turkey, rather than the 1-2 weeks previously suggested. Even then, approvals are not guaranteed within standard timeframes. Monitoring your status daily and having backup contact numbers for consulates is essential.

Above all, avoid assuming your e-visa request will be handled in 24-72 hours. The State Department cautions: “Applying for an e-visa does not guarantee entry into Turkey on the requested dates. Allow plenty of time for processing.” With consular resources stretched thin, build extra padding into your timeline. Unless you receive the official approved visa email, your trip hangs in the balance.
