In September, Microsoft made an unusual combination of announcements. It demonstrated progress with quantum error correction, something that will be needed for the ...

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 contrast to classical computers, which operate on bits that can only take the basic values 0 and 1, quantum computers operate on "qubits," which can assume any superposition of the computational ...

Quantum computing breakthroughs from IonQ, D-Wave, QuEra, Alice & Bob, and others in the last six months, with dates, achievements, and their impact on error-corrected, scalable quantum systems. May 7 ...

Researchers from Google have demonstrated a new generation of quantum computer, called Willow, which is able to run its random circuit sampling (RCS) benchmark significantly faster than a ...
