Massive astrophysical objects governed by subatomic equation

Quantum mechanics is the branch of physics governing the sometimes-strange behavior of the tiny particles that make up our universe. Equations describing the quantum world are generally confined to the subatomic realm—the ...

Supercomputing more light than heat

Solar cells can't stand the heat. Photovoltaics lose some energy as heat in converting sunlight to electricity. The reverse holds true for lights made with light-emitting diodes (LED), which convert electricity into light. ...

Trust is good, quantum trickery is better

An international team of scientists has proven, for the first time, the security of so-called device-independent quantum cryptography in a regime that is attainable with state-of-the-art quantum technology, thus paving the ...

Building blocks to create metamaterials

Engineers at Caltech and ETH Zürich in Switzerland have created a method to systematically design metamaterials using principles of quantum mechanics.

Researchers chart the 'secret' movement of quantum particles

Researchers from the University of Cambridge have taken a peek into the secretive domain of quantum mechanics. In a theoretical paper published in the journal Physical Review A, they have shown that the way that particles ...

Research team saves information on a single molecule

Over the past few years, the building blocks of storage media have become ever smaller. But further miniaturization of the current technology is hindered by fundamental limits of quantum mechanics. A new approach consists ...
