You have probably heard about the potential of quantum computers, and people have been making optimistic predictions for decades. These massively parallel computer systems could make enormous leaps in computing power, potentially surpassing all the transistor-based supercomputers we can develop today and tomorrow. But how close are we to the dream of quantum computing technology?

Quantum computers would provide the computing power needed to solve problems that cannot currently be solved on conventional computers, at least not within a workable timeframe. In the short term, I think the industry will focus on building a quantum computer that does a job really well, but it might not be a universal quantum computer that can do calculations in the way that conventional computers can. Quantum computing technology will be an important part of the work that we do and will continue to do, and we are all enthusiastic about it.

Quantum computers will also be useful for solving problems that even today’s most powerful computers cannot solve. While quantum computers would be able to crack many of today’s encryption techniques, my prediction is that they would create a hack-proof replacement. Using a quantum computer would require the development of new encryption techniques, as many existing techniques may be vulnerable to the algorithms running on them.

In order to execute quantum algorithms with practical effects, a quantum computer would have to have a very high degree of precision, such as a qubit computing rate per second. One of the reasons we do not have real quantum computers on a 1: 1 scale today is that no one can hold qubits stable for more than a few milliseconds. The ability to keep the bits calculated will be the key to realizing the potential of quantum computing technology. It is thought that they will devastate the classical computers, so there may be cases where Quantum computers cannot compute as much data as supercomputers.

IBM says it can double the power of quantum computers within a year, and at that point it could cross the threshold for certain types of problems that quantum machines can jump past, or at least start on. IBM says that they can double the power of a quantum computer in a year, allowing us to move on to certain problems that the quantum machine might have skipped to address, but at the same time, it may not be ready for the real world.

As someone who has worked on quantum computers for many years, I believe that a useful quantum computer is probably never built, as random hardware errors are inevitable. Although quantum cryptography is promising if we can solve the problem of quantum transmission, we doubt that this is true for generalized quantum computation. One thing Gil is emphasizing here is that now is the time to think about quantum algorithms and quantum circuits, so that they can be performed not only in theory but also in practice on a quantum computer.

Although quantum computers theoretically have incredible potential, and scientists in the IQC world are working to realize this potential, much remains to be done before they can be commercialized. While researchers are working on ways to transmit information using quantum bits, we have a basic quantum computer, but all we can imagine is tapping into a classic computer on a quantum computer. Certain tasks, such as e-mail, are not as suitable for Quantum computers, so modern computer systems are not set up to be replaced by them.

If you’re wondering how long it will take for quantum computers to do something really cool, you don’t have to live in the future. Given that the largest quantum computer today is IBM’s 53-qubit quantum computer, it could be a long time before we break through encryption. While quantum encryption may be able to prevent threats and protect governments and companies with sensitive secrets, communication and real-world applications will emerge as enablers of quantum computing technology. Since quantum computers are not yet technically capable of breaking most common forms of encryption, we now need to find a quantum-safe solution.

How close are we to the first quantum computer that could solve these problems before our computers today? You could buy quantum computing technology, but you are right that it is not only available and ready for business. Formally, a quantum computer can be simulated by a Turing machine, and it will be able to solve problems that are too complex for a classical computer to solve. Conversely, quantum computers obey the Church – Turing’s thesis, which means that classical computers can also solve all the arithmetical problems they can solve. Conversely, problems that can be solved with quantum computers can also be solved with classical computers. Any computing problem that can be solved with classical machines, such as the problem of quantum computation, can in principle be solved
