Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

In the world of quantum computing, the Hilbert space dimension—the measure of the number of quantum states that a quantum computer can access—is a prized possession. Having a larger Hilbert space ...

D-Wave's massive January acquisition of Quantum Circuits is paying off: way better error correction, making quantum computing ...

Computers also make mistakes. These are usually suppressed by technical measures or detected and corrected during the calculation. In quantum computers, this involves some effort, as no copy can be ...

To shrink error rates in quantum computers, sometimes more is better. More qubits, that is. The quantum bits, or qubits, that make up a quantum computer are prone to ...

UK-based Riverlane announced today it has secured $75mn in Series C funding to meet “surging global demand” for quantum error correction — and propel it on its ...
