(PhysOrg.com) -- Many scientists believe that quantum entanglement is required in order for effective quantum computing. Entanglement takes place when there is a connection that exists between two objects - even when they ...
(PhysOrg.com) -- When physicists experiment with quantum entanglement, they usually work with photons, the intangible particles of light. In the past few years, however, scientists have begun to broaden their experiments ...
Physicists have shown that simulating models of hypothetical time travel can solve experimental problems that appear impossible to solve using standard physics.

(Phys.org)—An international team of researchers has conducted an experiment that shows that the arrow of time is a relative concept, not an absolute one. In a paper uploaded to the arXiv server, the team describe their ...
(Phys.org)—Two Chinese teams working with quantum encryption and entanglement have achieved two more goals toward building a quantum space-based communication network. In the first experiment, one team succeeded in sending ...
Researchers from Stanford have advanced a long-standing problem in quantum physics – how to send "entangled" particles over long distances.

(Phys.org)—It was another good week for physics as an international team of researchers found a way to extend the lifetime of entangled particles by orders of magnitude by using coupled cavities—they adjusted the coupling ...
Physicists from MIT and the University of Belgrade have developed a new technique that can successfully entangle 3,000 atoms using only a single photon. The results, published today in the journal Nature, represent the largest ...
