Quantum entanglement in chemical reactions? Now there's a way to find out

Scientists have long suspected that a quantum phenomenon might play a role in photosynthesis and other chemical reactions of nature, but don't know for sure because such a phenomenon is so difficult to identify.

On-demand, photonic entanglement synthesizer

Quantum information protocols are based on a variety of entanglement modes such as Einstein-Podolsky-Rosen (EPR), Greenberger-Horne-Zeilinger (GHZ) and other cluster states. For on-demand preparation, these states can be ...

Quantum ghost imaging improved by using five-atom correlations

In conventional imaging methods, a beam of photons (or other particles) is reflected off the object to be imaged. After the beam travels to a detector, the information gathered there is used to create a photograph or other ...

Researchers demonstrated violation of Bell's inequality on frequency-bin entangled photon pairs

Quantum entanglement, one of the most intriguing features of multi-particle quantum systems, has become a fundamental building block in both quantum information processing and quantum computation. If two particles are entangled, ...

Researchers find a way to close both loopholes in testing entanglement with Bell's inequality

(—A team of researchers working at Delft University in The Netherlands, has perhaps succeeded in closing the two loopholes that have prevented proving that local realism does not hold at the quantum level. They ...

Physicists race to demystify Einstein's 'spooky' science

When it comes to fundamental physics, things can get spooky. At least that's what Albert Einstein said when describing the phenomenon of quantum entanglement—the linkage of particles in such a way that measurements performed ...

Probing quantum physics on a macroscopic scale

Why does quantum mechanics work so well for microscopic objects, yet macroscopic objects are described by classical physics? This question has bothered physicists since the development of quantum theory more than 100 years ...

Quantum computer coding in silicon now possible

A team of Australian engineers has proven—with the highest score ever obtained—that a quantum version of computer code can be written, and manipulated, using two quantum bits in a silicon microchip. The advance removes ...
