Exerting delicate control over a pair of atoms within a mere seven-millionths-of-a-second window of opportunity, physicists created an atomic circuit that may help quantum computing become a reality.

Typical superconducting quantum circuits, such as qubits—basic processing units of a quantum computer, must be operated at very low temperatures, of a few 10s of millikelvin, or hundredths of a ...

One notable breakthrough in the quantum-AI sector is Google’s Willow quantum chip, which solved a random circuit sampling (RCS) benchmark problem in just five minutes—a task that, according to ...

In the context of quantum mechanics and information, "magic" is a key property of quantum states that describes the extent to which they deviate from so-called stabilizer states. Stabilizer states are ...

First, the team generated random circuits and sent them to an untrusted remote quantum computer via the Internet, according to a press release. That computer was then asked to return corresponding ...

Researchers from the University of Queensland have taken a significant step in the quest to build a quantum computer, creating a light-based quantum circuit capable of basic calculations and ...

Superconducting electronics have arisen as a promising alternative for classical and quantum computing, although their full exploitation for high-end computing requires a dramatic reduction in the ...
