Google ‘Quantum Supremacy: From 50 trillion hours to 30 seconds AND From 10,000 years to 200 seconds

In a new scientific paper, Google researchers claim for the first time to have demonstrated “quantum supremacy,” where a quantum computer outperforms a traditional one.

“While our processor takes about 200 seconds to sample one instance of the quantum circuit 1 million times, a state-of-the-art supercomputer would require approximately 10,000 years to perform the equivalent task,” the researchers said.

Google’s quantum computer, dubbed “Sycamore,” contained 53-qubits, or “quantum bits,” a measure of the machine’s potential power. The team scaled back from a 72-qubit device, dubbed “Bristlecone,” it had previously designed.

The researchers estimate that performing the same experiment on a Google Cloud server would take 50 trillion hours—too long to be feasible. On the quantum processor, it took only 30 seconds, they said.
