Just a few years ago, many researchers in quantum computing thought it would take several decades to develop machines that could solve complex tasks, such as predicting how chemicals react or cracking ...

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 ...

There are currently about 80 companies across the world manufacturing quantum computing hardware. Because I report on quantum computing, I have had a chance to watch it grow as an industry from up ...

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 ...

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.” ...

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 ...

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 ...

In today's edition of The Edward Snowden Files, The Washington Post reports that the National Security Agency, with a plan that sounds like something Lex Luthor cooked up, is racing to build a quantum ...

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 ...

- 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, ...
