Google’s Quantum computer challenged by IBM

Yesterday, Google said that it’s quantum computer generated about 1 million random strings of numbers in roughly three minutes. According to Google, this would have taken 10000 years to complete if it was done by a supercomputer.

Quantum Computer harnesses properties of quantum physics and has the potential to sort through a vast number of possibilities in nearly real-time and come up with a probable solution. It computes its algorithms superfast.

Unlike traditional computers that store binary information, quantum computers stores information in quantum bits (qubits). A commercial-grade quantum computer could have as many as 1 million qubits. Binary information means either 1 or 0 and quantum bit information means both zeros and ones simultaneously.

Google disclosed that the company considers its self developed 54 qubit machine, Sycamore as a benchmark to measure future quantum-computing experiments.

John Martinis, Google’s chief scientist of quantum hardware said: “It’s really good news for the field that if we make more complicated systems, everything should work.” Martinis along with several researchers spoke to about a dozen journalists at Google’s California lab which comprised of about 35 researchers and hundreds of millions of dollars worth of quantum-computing equipment.

It should be noted that Google is still years away from building such a machine because it will have to contend with several hardware challenges before.

Moreover, Google’s claims to Quantum supremacy have been already challenged by IBM. In a blog post, IBM’s Edwin Pednault, John Gunnels, and Jay Gambetta have questioned the methods used by Google to achieve quantum supremacy on 21 October. They also pointed out that a classical supercomputer could do the same in 2.5 days or perhaps lesser time if all their resources are leveraged properly.

It should be remembered that back in January, IBM showed a prototype of their first commercial quantum computer, Q System One.
