Physicists find quantum coherence and quantum entanglement are two sides of the same coin
The importance of three-way atom interactions in maintaining coherence
Quantum computers will someday perform calculations impossible for conventional digital computers. But for that to happen, the core quantum information must be preserved against contamination from the environment. ...
Quantum world without queues could lead to better solar cells
In a recent study from Lund University in Sweden, researchers have used new technology to study extremely fast processes in solar cells. The research results form a concrete step towards more efficient solar cells.

Quantum biology: Algae evolved to switch quantum coherence on and off
A UNSW Australia-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis.
Researchers confirm 60-year-old prediction of atomic behavior
Researchers at Washington State University have used a super-cold cloud of atoms that behaves like a single atom to see a phenomenon predicted 60 years ago and witnessed only once since.
Quantum-to-classical transition may be explained by fuzziness of measurement references
Quantum effects help cells capture light, but the details are obscure
Sophisticated recent experiments with ultrashort laser pulses support the idea that intuition-defying quantum interactions between molecules help plants, algae, and some bacteria efficiently gather light to fuel their growth. ...
Diamond 'flaws' pave way for nanoscale MRI
Breakthrough offers high-sensitivity nanoscale sensors, and could lead to magnetic imaging of neuron activity and thermometry on a single living cell.
Searching for quantum physics in all the right places
An improved method for measuring quantum properties offers new insight into the unique characteristics of quantum systems.
A physicist's best friend: Quantum coherence in diamond augments fluorescence thermometry
Entanglement in a flash (w/ video)
(Phys.org) —JQI researchers under the direction of Chris Monroe have produced quantum entanglement between a single atom's motion and its spin state thousands of times faster than previously reported, demonstrating unprecedented ...
On a clear day: Noise-induced quantum coherence increases photosynthetic yield
Noise is not necessarily detrimental to quantum devices
The researches of the Aalto University and the University of Oulu have succeeded to simulate a phenomenon called motional averaging, which demonstrates that in certain conditions externally-induced fast fluctuations ...
