A team of engineers, physicists and quantum specialists at Google Research has found that reducing noise to a certain level allows the company's sycamore quantum chip to beat classical computers ...

Evidence that a quantum computer can solve a problem faster than a classical computer – quantum advantage – is therefore a key measure of success. The first claim of quantum advantage came in 2019, ...

While past studies have successfully tackled random sampling tasks using quantum computers, actually verifying that a system effectively performs these tasks has proved challenging.

Random circuit sampling is the technique Google has put forward to prove whether or not it has achieved quantum supremacy with a 72-qubit computer chip called Bristlecone, unveiled earlier this year.

In fact, random circuit sampling – in which all qubits are initialized in a given state and allowed to evolve via quantum gates before having their states measured at the output – is often used to ...

To generate certified randomness, the team used a method called random circuit sampling, or RCS. The idea is to feed the quantum computer a series of tough problems, known as challenge circuits.

Random quantum circuit easiest way to beat classical computer Researchers suggest modeling chaotic circuits to demonstrate quantum supremacy. Chris Lee – May 1, 2018 2:50 pm | 35 ...

Using a 56-qubit quantum computer, they have for the first time experimentally demonstrated certified randomness, a way of generating random numbers from a quantum computer and then using a ...
