Two companies that are racing to develop a photonic quantum computer using photonic qubits are PsiQuantum, based in Palo Alto ...

Scientists have demonstrated that a photonic qubit — a quantum bit powered by a particle of light — can detect and correct its own errors while running at room temperature. They say it is a ...

Large-scale quantum computers will need far more than better qubits—they will need a practical way to control and read them ...

Chip-scale laser controls trapped ions for quantum clocks and qubits, enabling portable, scalable systems with high fidelity ...

A team of Harvard physicists built the first-ever quantum computing machine that can operate continuously without restarting, achieving a major breakthrough in a field that could revolutionize ...

A time crystal more complex than any made before has been created in a quantum computer. Exploring the properties of this unusual quantum setup strengthens the case for quantum computers as machines ...
