Simplifying the process of detecting genuine multiparticle entanglement
Never mind the noise: Quantum entanglement allows channel information rate to exceed Shannon zero-error capacity
Physicists Investigate Unusual Four-Qubit Entanglement
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 ...
Researchers propose using distant quasars to test Bell's theorem
In a paper published this week in the journal Physical Review Letters, MIT researchers propose an experiment that may close the last major loophole of Bell's inequality—a 50-year-old theorem that, if vio ...
Entanglement recycling makes teleportation more practical
New method to detect quantum mechanical effects in ordinary objects
At the quantum level, the atoms that make up matter and the photons that make up light behave in a number of seemingly bizarre ways. Particles can exist in "superposition," in more than one state at the same ...
'Quantum magic' without any 'spooky action at a distance'
The quantum mechanical entanglement is at the heart of the famous quantum teleportation experiment and was referred to by Albert Einstein as "spooky action at a distance". A team of researchers led by Anton ...
Using degrees of freedom to get hyperentanglement
Caught on camera: quantum mechanics in action
(Phys.org) -- Scientists at the University of Glasgow have captured images of ‘quantum entanglement’ on camera for the first time.
Quantum networks advance with entanglement of photons, solid-state qubits
A team of Harvard physicists led by Mikhail D. Lukin has achieved the first-ever quantum entanglement of photons and solid-state materials. The work marks a key advance toward practical quantum networks, as ...
The quantum world writ large: Using short optical pulses to study macroscopic quantum behavior
More accurate than Heisenberg allows? Uncertainty in the presence of a quantum memory
Quantum cryptography is the safest way to encrypt data. It utilizes the fact that transmitted information can only be measured with a strictly limited degree of precision. Scientists at Ludwig-Maximilians-University in Munich ...
