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.

Did Google really achieve quantum supremacy?

Google has officially announced that it's achieved quantum supremacy in a new article published in the scientific journal Nature. ... Google says that its 54-qubit Sycamore processor was able to perform a calculation in 200 seconds that would have taken the world's most powerful supercomputer 10,000 years.

Who has achieved quantum supremacy?

On September 20, 2019, the Financial Times reported that "Google claims to have reached quantum supremacy with an array of 54 qubits out of which 53 were functional, which were used to perform a series of operations in 200 seconds that would take a supercomputer about 10,000 years to complete".
