Sound as qubit link: Harvard engineers coupled a single phonon to a single atomic spin, enabling sound to act as a quantum information carrier. Magnetic field control: Cal Poly research shows ...

MIT physicists have synthesized a new family of bulk crystals whose electrons behave as though they move in an effectively four-dimensional “superspace,” rather than being fully described by the three ...

A special class of sensors leverages quantum properties to measure tiny signals at levels that would be impossible using classical sensors alone. Such quantum sensors are currently being used to study ...

In physics, breakthroughs are rare. Experiments are slow, expensive and often end up refining, rather than rewriting, our understanding of the universe. But what if the only constraint on scientific ...

A thought experiment that was at the heart of an argument between famed physicists Albert Einstein and Niels Bohr in 1927 has finally been made real. Its findings elucidate one of the core mysteries ...

The most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...
