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

Quantum computers, computing systems that process information using quantum mechanical effects, could outperform classical computers on some computational tasks. These computers rely on qubits, the ...

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 ...

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 ...

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

There are currently about 80 companies across the world manufacturing quantum computing hardware. Because I report on quantum computing, I have had a chance to watch it grow as an industry from up ...
