In what specific cases do quantum computers surpass their classical counterparts? That’s a hard question to answer, in part because today’s quantum computers are finicky things, plagued with errors ...

Several years ago, University of Texas Austin computer scientists Scott Aaronson and Shih-Han Hung proposed a way to generate certified random bits based on random circuit sampling – a method to ...

Last year, Foss-Feig and his colleagues at Quantinuum successfully used a quantum computer they developed to complete random circuit sampling tasks that could not be completed by classical ...

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 ...

Quantum advantage: Schematic diagram of the Zuchongzhi-3 chip. 105 qubits and 182 couplers are integrated on the same chip to perform quantum random circuit sampling tasks. (Courtesy: USTC) ...

To create their random number, the researcher used a technique called random circuit sampling. It essentially leans on quantum computing (which operates under different rules than classical computing ...

Zuchongzhi-3, a superconducting quantum computing prototype with 105 qubits and 182 couplers, has made significant advancements in random quantum circuit sampling. This prototype was successfully ...

A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen and is meant to be an unbiased representation of a group.
