Large-scale quantum computers are waiting in the wings. One of the main reasons we don't have them yet is because quantum hardware is so noisy. This isn't the type of noise you'd want to shush in a ...

For quantum computers to function, they must be kept at extremely low temperatures. However, today's cooling systems also generate noise that interferes with the fragile quantum information they are ...

The idea behind quantum computing has existed for a long while now, with the primary goal being to basically create supercomputers capable of calculating intensive problems almost instantly. While we ...

Physicist Jay Gambetta, at IBM’s lab in Yorktown Heights, New York, explains how microwaves orchestrate a solution on a quantum chip: “Think of each qubit as a line in music. You’re creating notes.” ...

What is it about quantum computers that makes them more powerful than conventional machines? A new experiment shows that the property of “quantum contextuality” may be a key ingredient. Quantum ...

Quantum Elements, a Los Angeles startup, has demonstrated a new technique for suppressing errors in logical qubits that shows the highest fidelity of entangled, logical qubits on a superconducting ...

Researchers developed a simple quantum refrigerator that uses environmental noise to control heat and energy flows, aiding precise cooling for quantum computing. (Nanowerk News) For quantum computers ...
