Quantum Computing - Is it the Future?
Quantum computers, while still under development, clearly have the ability to outperform conventional computers. They require more advanced techniques and more cutting-edge quantum theory, with advantages in optimizing computational efficiency and computational power. The key to the future development of computational science lies in the application of quantum theory to various areas of computer science.
“Quantum computers will not only open up a higher processing speed, but also applications we never thought of before.”
——Ray Laflamme, Executive Director, Institute for Quantum Computing,
University of Waterloo, Canada
Traffic ControlWhat is Quantum Computing?
Traditional computers use a "long bit", which is a basic unit of information that contains a binary value of "0" or "1". In contrast, a quantum computer uses qubits, which can hold either or both values at the same time. This is due to a quantum physical phenomenon called superposition. Superposition occurs when two or more quantum states of a subatomic particle, such as the "spin up" and "spin down" spin states, hold simultaneously. In quantum computing, superposition can be understood as a qubit being both "0" and "1" at the same time.
Using subatomic particles that can exist in multiple states could make quantum computers faster and use less energy than conventional ones. NASA scientists, for example, built a quantum computer in 2016 that was 100 million times faster than a conventional computer.
If the research team at Google and the University of California, Santa Barbara, can build a chip with 50 qubits, quantum supremacy will be achieved very quickly.
"The computational power of a quantum computer grows exponentially with the number of qubits that are manipulated," says Alexey Kavokin of the Russian Quantum Center (RQC).
Benefits of Quantum Computing
The performance advantage of this type of computing power comes from its ability to quickly analyze and test extremely large datasets. Here are some examples of how quantum computing will affect our world.
Cryptography
At present, most network security methods rely on processing massive amounts of data through computers, which takes a lot of time to "crack the password". Quantum computers promise to produce codes that are fundamentally unbreakable and add data encryption capabilities.
Medical Research
Quantum computing will potentially allow chemists to test millions of combinations of molecules when developing new drugs, determining which ones are most likely to succeed in clinical trials. In addition, quantum computing could significantly reduce the cost and time to bring them to market, make it easier to use preapproved drugs for novel applications, and enable computational chemists to innovate to treat a wide range of diseases faster.
Weather Forecasting
Any weather prediction is done by analyzing large and complex data sets. Traditional weather simulations are limited by the inputs that a conventional computer can manage. If too many coherence factors are added, the simulation will take longer than the actual weather evolution time. Quantum computing has the ability to process large amounts of data that can help make more accurate predictions a
Both air and road traffic would benefit from quantum computing's ability to analyze traffic flow control. They will be able to quickly calculate the optimal route, which will improve traffic efficiency and reduce traffic congestion.
