Researchers at QuTech in Delft have succeeded in generating quantum entanglement between two quantum chips faster than the entanglement is lost. Via a novel smart entanglement protocol and careful protection of the entanglement, ...

(Phys.org)—Quantum entanglement—which occurs when two or more particles are correlated in such a way that they can influence each other even across large distances—is not an all-or-nothing phenomenon, but occurs in ...
Energy is a quantity that must always be positive—at least that's what our intuition tells us. If every single particle is removed from a certain volume until there is nothing left that could possibly carry energy, then ...

JILA and NIST Fellow James K. Thompson's team of researchers have for the first time successfully combined two of the "spookiest" features of quantum mechanics to make a better quantum sensor: entanglement between atoms ...

(Phys.org)—As an elementary particle, the electron cannot be broken down into smaller particles, at least as far as is currently known. However, in a phenomenon called electron fractionalization, in certain materials an ...
(Phys.org)—A lot of attention has been given to the differences between the quantum and classical worlds. For example, quantum entanglement, superposition, and teleportation are purely quantum phenomena with no classical ...
If a tree falls in a forest and no one is there to hear it, does it make a sound? Perhaps not, some say.

(Phys.org) —In theory, Maxwell's demon can decrease the entropy of a system by opening and closing a door at appropriate times to separate hot and cold gas molecules. But as physicist Leó Szilárd pointed out in 1929, ...
The fundamental resource that drives a quantum computer is entanglement—the connection between two distant particles which Einstein famously called 'spooky action at a distance'. The Bristol researchers have, for the ...
