Quantum engines must break down

Our present understanding of thermodynamics is fundamentally incorrect if applied to small systems and needs to be modified, according to new research from University College London (UCL) and the University of Gdańsk. The ...

Playing quantum tricks with measurements

A team of physicists at the University of Innsbruck, Austria, performed an experiment that seems to contradict the foundations of quantum theory—at first glance. The team led by Rainer Blatt reversed a quantum measurement ...

Quantum copies do new tricks

One of the strange features of quantum information is that, unlike almost every other type of information, it cannot be perfectly copied. For example, it is impossible to take a single photon and make a number of photons ...

The economics of database searching

(PhysOrg.com) -- Searching the internet might seem simple, but applying a little bit of economic theory to information retrieval can shed some light on the best search strategies to adopt, according to researchers.

Quantum knowledge cools computers: New understanding of entropy

From a laptop warming a knee to a supercomputer heating a room, the idea that computers generate heat is familiar to everyone. But theoretical physicists have discovered something astonishing: not only do computational processes ...

Common orchid gives scientists hope in face of climate change

A study led by scientists from the Royal Botanic Gardens, Kew's Jodrell Laboratory, which focuses on epigenetics in European common marsh orchids, has revealed that some plants may be able to adapt more quickly to environmental ...
