IBM is the first to demonstrate the advantage of quantum computers over classic – NeeWS

IBM was the first to clean the dishes for the development of quantum computers. The company is a world pioneer in their development, and also offers companies the largest number of quantum computing systems in the clouds for performing advanced simulations.

Now, finally, the company has published the results of the experiment, which clearly shows the current advantage of quantum computers over traditional ones. And it’s not just about forecasts, but about the actual state of affairs, that is, the present value in use. “Already, qubits offer more value than bits as a storage medium for calculations”- they wrote in their blog. You can read the study here (Look here).

From the latest scientific article published in the prestigious Nature Physics, entitled “Quantum Advantage in Computing with Limited Space”, we can learn that IBM researchers have proven that there are functions that a limited classical computer cannot calculate, but a quantum computer with constraints maybe already. To this end, they combined a real quantum computer with a classical computer.

To increase the computational capabilities of the classic computer used in the experiment, scientists armed it with access to random logic gates. However, even with access to this randomness, the classic computer was still only able to be successful 87.5% of the time, while a perfect, noiseless quantum computer could only be successful 100% of the time.

Although in this particular case we are still talking about the comparison of a classical quantum machine with a future quantum machine, IBM’s quantum computers already under development are able to achieve a success rate of 93%, which is 7% less than the perfect machines of the future, but by 5 5% more than traditional computers. We are talking here about real experiments, not numbers on paper.

This shows how, at this stage in the development of quantum computers and quantum computing systems, these machines offer extraordinary possibilities. This fact should not come as a surprise, after all, dozens of companies from around the world use the systems offered by IBM on a daily basis. This allows them to create simulations that are unattainable by traditional units.

It is worth adding here that as part of the Discovery Accelerator project, IBM will install the first commercial quantum computer at the Cleveland Clinic, where it will be used to discover new drugs for dangerous diseases. It will be an IBM Quantum System One with a capacity of 20 qubits. In the near future, scientists will also be able to work on its successor, i.e. a quantum computer with a capacity of up to 1000 qubits, on which IBM engineers are working intensively.

IBM has set itself a very ambitious goal. Within a few years, it is to develop a quantum computer working on over 1000 qubits, or quantum bits. The company wants to be the first to achieve the so-called quantum supremacy, namely then these machines of the future will finally triumph over traditional devices, as they will be able to perform every possible operation, even those that are not and never will be available to even the fastest supercomputers in history.
