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 ...

Astronaut John Glenn was wary about trusting a computer. It was 1962, early in the computer age, and a room-sized machine had calculated the flight path for his upcoming orbit of Earth — the first for ...

Quantum computing is still in its infancy, easily beaten by traditional computers. One of the biggest challenges? The fact that quantum bits — qubits — are much more fragile than the bits in silicon ...

These novel error-correction codes can handle quantum codes with hundreds of thousands of qubits, potentially enabling large-scale fault-tolerant quantum computing, with applications in diverse fields ...
