Did Google achieve quantum supremacy?

Did Google achieve quantum supremacy?

In October 2019, Google scientists announced they’d achieved “quantum supremacy,” the long-sought proof that a computer built around the strange properties of quantum mechanics can, at least in certain cases, carry out calculations exponentially faster than a computer built around classical bits.

What is meant by quantum supremacy Why is there so much in the news about it?

In quantum computing, quantum supremacy or quantum advantage is the goal of demonstrating that a programmable quantum device can solve a problem that no classical computer can solve in any feasible amount of time (irrespective of the usefulness of the problem).

Can quantum computers solve P NP?

Quantum computers can solve NP-hard problems that classical computers are unable to solve. Currently, the two most important and notable complexity classes are “P” and “NP.” P represents problems that can be solved in polynomial time by a classical computer.

Can quantum computer replace classical computers?

Quantum Computers are not meant to replace the Classical ones. Instead, the world of computation can be rewired to work within a symbiotic mutualism of quantum and classical computers: Quantum-Classical Hybrid Model.

What do you understand by quantum supremacy What can be the possible application of quantum computing?

Quantum supremacy refers to a quantum computer solving a problem that cannot be expected of a classical computer in a normal lifetime. Hence, they far exceed the speed and capability of classical supercomputing.

Does Google’s ‘quantum supremacy’ claim hold up?

They add that because “quantum supremacy” requires a quantum computer to solve a problem that is beyond a classical computer, Google’s claim does not hold up. “Google’s experiment is an excellent demonstration of the progress in superconducting-based quantum computing,” the IBM scientists argue.

Can quantum computers achieve quantum supremacy?

To achieve quantum supremacy, a quantum computer would have to perform any calculation that, for all practical purposes, a classical computer can’t. In one sense, the milestone is artificial. The task that will be used to test quantum supremacy is contrived — more of a parlor trick than a useful advance (more on this shortly).

Is Google’s superconducting quantum computing proof that quantum computers are superior?

“Google’s experiment is an excellent demonstration of the progress in superconducting-based quantum computing,” the IBM scientists argue. “But it should not be viewed as proof that quantum computers are ‘supreme’ over classical computers.”

Can quantum computers really outperform classical ones?

There have been working quantum computers for several years, but it’s only under certain conditions that they outperform classical ones, and in October Google claimed the first such demonstration of “quantum supremacy.”
