In a study, physicists now observed a class of quantum particles called fractional excitons, which behave in unexpected ways and could significantly expand scientists' understanding of the quantum ...

Using a powerful machine made up of 56 trapped-ion quantum bits, or qubits, researchers have achieved something once thought impossible. They have proven, for the first time, that a quantum computer ...

A quantum bit inspired by Schrödinger’s cat has managed to resist making errors for an unusually long time in a quantum computing experiment. This may make it a promising building block for more ...

Quantum computers hold great promise for exciting applications in the future, but for now they keep presenting physicists and engineers with a series of challenges and conundrums. One of them relates ...

Researchers at the Duke Quantum Center received a $1 million grant to plan a 256-qubit quantum computer, kicking off an effort to build the most powerful computer ever of its kind. The production of ...

On Thursday, Amazon unveiled its first-ever quantum computing chip. This follows similar announcements from Microsoft and Google. Research into quantum computing, which could speed up some computing ...

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 ...
