The commonly used RSA encryption algorithm can now be cracked by a quantum computer with only 100,000 qubits, but the technical challenges to building such a machine remain numerous ...

Quantum computers need special materials called topological superconductors—but they’ve been notoriously difficult to create. Researchers have now shown they can trigger this exotic state by subtly ...

John Martinis has already revolutionised quantum computing twice. Now, he is working on another radical rethink of the technology that could deliver machines with unrivalled capabilities ...

Chicago has quickly emerged as a hub for quantum computing, with the state of Illinois and technology companies pouring millions of dollars into developing a campus to build the world’s first ...

What is superconducting quantum computing? Superconducting quantum computing (SQC) describes one way that a quantum computer can be built. A computer built on these principles uses tiny ...

Physicist Jay Gambetta, at IBM’s lab in Yorktown Heights, New York, explains how microwaves orchestrate a solution on a quantum chip: “Think of each qubit as a line in music. You’re creating notes.” ...

- Distributed quantum network could lay groundwork towards quantum computing internet defined by quantum computers, sensors, and communication in the late 2030s YORKTOWN HEIGHTS, N.Y. and SAN JOSE, ...

Paris-based quantum computing startup Alice & Bob has announced a stunning breakthrough in quantum computing: its qubits can now resist bit-flip errors for more than an hour. That’s four times longer ...

Just weeks after the IT and networking giant revealed that it had developed software designed to make the new networking paradigm work through networking application demos for classical use cases, ...
