Novel particle beam could challenge Einstein's theory of gravity

Does gravity act equally on all particles in the universe, or are there differences between ordinary and exotic matter? Physics professor Anna Soter and her team at ETH Zurich and the Paul Scherrer Institute (PSI) in Villigen ...

Scientists build world's most accurate atomic clock

Take a second and turn it into trillions of moments. Measure each one. That's how precisely an atomic clock at Singapore's Centre for Quantum Technologies (CQT) keeps time—and with record-setting accuracy, according to results ...

Real-time quantum jump in sound observed for first time

A Stanford team has documented the first direct observation of quantum jumps of sound in a mechanical resonator, completing an arc of scientific exploration that started more than 100 years ago.

Quantum device simulates matter popping into existence

A research team led by faculty at the Duke Quantum Center (DQC) has observed string-breaking dynamics related to particle-antiparticle formation on a quantum simulator, among the first such observations in quantum physics.

Q&A: How will quantum computers change society?

Once called a "pipe dream," quantum computers are now approaching practical use. Companies and research institutes around the world are in fierce competition to develop this technology, which has the potential to rapidly ...
