Could some entangled states be useless for quantum cryptography?
How losing information can benefit quantum computing
Suggesting that quantum computers might benefit from losing some data, physicists at the National Institute of Standards and Technology (NIST) have entangled—linked the quantum properties of—two ions ...
Researchers show that relatively simple physical systems could yield powerful quantum computers
Quantum computers are devices—still largely theoretical—that could perform certain types of computations much faster than classical computers; one way they might do that is by exploiting "spin," a property ...
14 quantum bits: Physicists go beyond the limits of what is currently possible in quantum computation
(PhysOrg.com) -- Quantum physicists from the University of Innsbruck (Austria) have set another world record: They have achieved controlled entanglement of 14 quantum bits (qubits) and, thus, realized the ...

Longer distance quantum teleportation achieved
Physicists at the University of Geneva have succeeded in teleporting the quantum state of a photon to a crystal over 25 kilometers of optical fiber.
Hydrogel remembers its shape
(Phys.org)—A bit reminiscent of the Terminator T-1000, a new material created by Cornell researchers is so soft that it can flow like a liquid and then, strangely, return to its original shape.
Chinese team entangles eight photons, breaking record
Physicists aim to make transition to quantum world visible
Theoretical physicist Frank Wilhelm-Mauch and his research team at Saarland University have developed a mathematical model for a type of microscopic test lab that could provide new and deeper insight into ...
New study suggests researchers can now test the 'theory of everything'
(PhysOrg.com) -- Researchers describe how to carry out the first experimental test of string theory in a paper published tomorrow in Physical Review Letters.
10 billion bits of entanglement achieved in silicon
(PhysOrg.com) -- Scientists from Oxford University have made a significant step towards an ultrafast quantum computer by successfully generating 10 billion bits of quantum entanglement in silicon for the first ...
Mathematical breakthrough sets out rules for more effective teleportation
For the last ten years, theoretical physicists have shown that the intense connections generated between particles as established in the quantum law of 'entanglement' may hold the key to eventual teleportation of quantum ...
Entanglement made tangible
EPFL scientists have designed a first-ever experiment for demonstrating quantum entanglement in the macroscopic realm. Unlike other such proposals, the experiment is relatively easy to set up and run with existing semiconductor ...
