The sheer fact that quantum computer can carry out million times faster calculations than modern day computers can have significant impact on the cryptographic system we rely on to encrypt and secure our data. However, it also draws attention to the fact that the technology is still in a very nascent stage and whether it can actually take over from existing computers without causing any major disruption, is yet to be seen. IBM’s reservations about Google’ claim on quantum supremacy can be seen as a classical tete-e-tete between two major technology giants where one is trying to take the limelight away from the other. This is what makes it forward compatible for the implementation of quantum error-correction (a process which minimises scope of error in quantum computation).

Google on its part, claims the Sycamore chip has been designed in a two-dimensional grid where each qubit is connected to four other qubits.

In October 2018, a UC Berkley PHD student Urmila Mahadev presented a measurement protocol which would allow a classical computer to interactively verify the result of a quantum computation.īuilding an error free quantum computer is another challenge as there is no way to validate the results. It will be many years before we can implement a broader set of real-world applications."Īnother limitation of quantum computer is that once it carries out a computation that an existing supercomputer cannot, there is no way to determine if the results are correct or not. In a blog post, Google CEO Sundar Pichai notes, “We have a long way to go between today’s lab experiments and tomorrow’s practical applications.
While Google believes that quantum supremacy is a major milestone in quantum computing, the company also acknowledges the fact that they are still many years away from using the technology to solve real world problems. Reacting to IBM's claims, Sergio Boixo, Chief Scientist Quantum Hardware, pointed out that Google will open source the quantum simulations used to achieve the quantum supremacy in order to facilitate other groups to analyse and validate their data and techniques. While IBM is widely regarded as a pioneer in the field, its prototypes are still far from ready to solve the complex problems at a commercial level. IBM showed a prototype of its first commercial quantum computer called Q system One in January 2019 and went on to open a quantum computation centre in New York in Sep 2019, giving researchers, educators and developers access to 10 quantum systems. They called Google’s experiment an excellent demonstration of the progress in superconducting-based quantum computing, but cautioned against seeing it as proof that quantum computers are superior to classical computers. The IBM blog hails quantum systems as a feat of science and engineering, and also point out that benchmarking them is an enormous challenge.
