The promise of so-called “quantum advantage” is simple. By harnessing the counterintuitive rules of quantum mechanics, quantum computers should be able to—in theory—surpass the computational potential ...

A cryostat from a quantum computer stands during a press tour of the Leibniz Computing Center in 2022. Qubit is a key term in one of the most buzzy areas of technology: quantum computing. Qubits are ...

In a major step toward practical quantum computers, Princeton engineers have built a superconducting qubit that lasts three times longer than today’s best versions. “The real challenge, the thing that ...

David Reilly and his University of Sidney team developed a silicon chip that can control spin qubits at milli-kelvin temperatures. That’s just slightly above absolute zero (-273.15 degrees Celsius), ...

Everyone in quantum computing agrees that error correction will be the key to doing a broad range of useful calculations. But early every company in the field seems ...

Today, a startup called Atom Computing announced that it has been doing internal testing of a 1,180 qubit quantum computer and will be making it available to customers next year. The system represents ...
