Quantum researchers create an error-correcting cat

Yale physicists have developed an error-correcting cat—a new device that combines the Schrödinger's cat concept of superposition (a physical system existing in two states at once) with the ability to fix some of the trickiest ...

Quantum gravity's tangled time

The theories of quantum mechanics and gravity are notorious for being incompatible, despite the efforts of scores of physicists over the past fifty years. However, recently an international team of researchers led by physicists ...

Generation of light in a photon-number quantum superposition

Physicists at C2N have demonstrated for the first time the direct generation of light in a state that is simultaneously a single photon, two photons, and no photon at all. They showed that the same kind of light emitter used ...

Physicists create record-setting quantum motion

Showcasing precise control at the quantum level, physicists at the National Institute of Standards and Technology (NIST) have developed a method for making an ion (electrically charged atom) display exact quantities of quantum-level ...
