How quantum mechanics can change computing

In early July, Google announced that it will expand its commercially available cloud computing services to include quantum computing. A similar service has been available from IBM since May. These aren't services most regular ...

Massive particles test standard quantum theory

In quantum mechanics particles can behave as waves and take many paths through an experiment. It requires only combinations of pairs of paths, rather than three or more, to determine the probability for a particle to arrive ...

Physics discovery unlocks ingredients of 2-D 'sandwich'

Everything that exists in the digital world—photos, tweets, online courses, this article—is stored as 1's and 0's. At the software level, this information is written as computer code. At the hardware level, that code ...

Study sheds light on the role of the entropy in a quantum system

Any understanding of the irreversibility of the arrow of time should account the quantum nature of the world that surrounds us. The is the key result of the work carried out by Vincenzo Alba and Pasquale Calabrese of the ...

Scientists observe gravitational anomaly on Earth

Modern physics has accustomed us to strange and counterintuitive notions of reality—especially quantum physics which is famous for leaving physical objects in strange states of superposition. For example, Schrödinger's ...

Adventures in acoustic cosmology

A project that explores whether there is a musical equivalent to the curvature of spacetime will be presented on Thursday 6 July by Gavin Starks at the National Astronomy Meeting at the University of Hull.
