Scientists find quantum mechanics at work in photosynthesis
(PhysOrg.com) -- A team of University of Toronto chemists have made a major contribution to the emerging field of quantum biology, observing quantum mechanics at work in photosynthesis in marine algae.
Getting around the 'uncertainty principle': Physicists make first direct measurements of polarization states of light
Researchers at the University of Rochester and the University of Ottawa have applied a recently developed technique to directly measure for the first time the polarization states of light. Their work both ...

The quantum computer is growing up: Repetitive error correction in a quantum processor
(PhysOrg.com) -- A team of physicists at the University of Innsbruck, led by Philipp Schindler and Rainer Blatt, has been the first to demonstrate a crucial element for a future functioning quantum computer: ...
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 ...
New way to calculate the effects of Casimir forces
(PhysOrg.com) -- MIT researchers have developed a powerful new tool for calculating the effects of Casimir forces, complicated quantum forces that affect only objects that are very, very close together, with ...
Scientists manage to study the physics that connect the classical the quantum world
How does a classical temperature form in the quantum world? An experiment at the Vienna University of Technology has directly observed the emergence and the spreading of a temperature in a quantum system. ...
