Google declares ‘quantum supremacy’ with chip of the future

San Francisco: Google CEO Sundar Pichai on Wednesday announced the team at Google AI has achieved sort of “quantum supremacy” with developing a chip that performed the target computation in 200 seconds, which would otherwise take the world’s fastest supercomputer 10,000 years.
Published in the journal Nature, the Google AP paper said the team developed a new 54-qubit processor, named “Sycamore”, that is comprised of fast, high-fidelity quantum logic gates, in order to perform the benchmark testing.
“Very proud that our @GoogleAI team has achieved a big breakthrough in quantum computing known as quantum supremacy after over a decade of work, as published in @Nature. Thank you to our collaborators in the research community who helped make this possible,” tweeted Pichai.
The quantum supremacy experiment was run on a fully programmable 54-qubit processor named.
It is comprised of a two-dimensional grid where each qubit is connected to four other qubits.
As a consequence, the chip has enough connectivity that the qubit states quickly interact throughout the entire processor, making the overall state impossible to emulate efficiently with a classical computer.
