#snsinstitutions #snsdesignthinkers #designthinking "UNLOCKING THE POTENTIAL OF QUANTUM COMPUTING" Quantum computing, a revolutionary paradigm in computational science, holds the promise of solving complex problems that are currently beyond the reach of classical computers. Unlike classical computers that use bits to represent information as either 0s or 1s, quantum computers utilize quantum bits, or qubits, which can exist in multiple states simultaneously thanks to the principles of superposition and entanglement. One of the most significant advantages of quantum computing is its potential to exponentially speed up computations for certain tasks. For example, quantum computers have the potential to revolutionize cryptography by breaking traditional encryption methods much faster than classical computers. They could also accelerate drug discovery, optimize supply chains, and enhance machine learning algorithms. Despite the tremendous promise, quantum computing is still in its infancy. Building and maintaining stable qubits remains a major challenge due to factors like decoherence, which causes quantum states to collapse before computations can be completed. Additionally, scaling quantum systems to a level where they can outperform classical computers for practical tasks requires overcoming significant engineering hurdles. However, recent advancements in quantum hardware, error correction techniques, and algorithm development are propelling the field forward. Major tech companies, research institutions, and governments are investing heavily in quantum computing research and development, driving progress towards achieving quantum supremacy – the point at which quantum computers can perform tasks that are infeasible for classical computers. As the field continues to evolve, interdisciplinary collaboration among physicists, computer scientists, engineers, and mathematicians will be crucial for realizing the full potential of quantum computing. While practical, large-scale quantum computers are still on the horizon, the rapid pace of innovation suggests that the era of quantum computing is approaching, promising to revolutionize fields across science, technology, and industry.

For Day 5 #Quantum30 Cohort 5, I completed studying section 1.5 of Quantum Computer Systems Research for Noisy Intermediate Scale Quantum Computer Areas of Research in Quantum computing: Error suppression: The control signals are altered or added to bring back the noise-affected qubits to their original states. This is the closest error-handling technique to hardware. An example is a spin echo. Error Correction: QEC can be performed using redundancy encoding (also used in classical computing), i.e., grouping multiple “physical qubits” to make one “logical qubit”, resulting in a very large machine. Gates that can work on this group of physical qubits as efficiently as on one logical qubit are implemented, and some set of operations and measurements (error-tolerant algorithms) are carried out to identify and fix errors. Error Mitigation: In error mitigation, the result is the average output of a group of circuits. There are many different types of error mitigation techniques. It is expected to be very important in the near term. Beyond several hundreds of qubits scale, hybrid error mitigation and error correction techniques are expected. It is practical to focus on smaller-scale algorithms, such as quantum simulation, and quantum chemistry, before dealing with large-scale algorithms such as Shor’s and Grover’s algorithms. However, there is still an inadequacy of QC machines to carry out small-scale algorithms. Quantum Compilation: The inadequacy of QC machines can be improved by optimization of quantum gates through compilation, which has proven to be more efficient than human-optimized circuits. Mapping and scheduling computations, and making machine-specific operators are some other crucial targets for optimization. The future applications of QC include, but is not limited to, finance and machine learning. Sources: 1. Ding, Y., & Chong, F. T. (2020).

Quantum computers can perform calculations in parallel thanks to the laws of quantum mechanics and entanglement between qubits, meaning the fates of different qubits can instantly change each other. Classical computers, by contrast, can work only in sequence. Adding more qubits to a system also scales up the power of a machine exponentially; scientists predict that quantum computers will one day perform complex calculations in seconds that a classical supercomputer would have taken thousands of years to solve. The point where quantum computers overtake classical ones is known as "quantum supremacy," but achieving this milestone in a practical way would need a quantum computer with millions of qubits. The largest machine today has only about 1,000 qubits. The reason we would need so many qubits for "quantum supremacy" is that they are inherently prone to error, so many would be needed to correct those errors. That's why many researchers are now focusing on building more reliable qubits, rather than simply adding more qubits to machines. A new quantum computer has broken a world record in "quantum supremacy," topping the performance of benchmarking set by Google's Sycamore machine by 100-fold. Using the new 56-qubit H2-1 computer, scientists at quantum computing company Quantinuum ran various experiments to benchmark the machine's performance levels and the quality of the qubits used. They published their results June 4 in a study uploaded to the preprint database arXiv. The study has not been peer-reviewed yet. #quantum #supremacy #computing #performance #qbits https://lnkd.in/g63x9SWv
