Team finds 'tipping point' between quantum and classical worlds
If we are ever to fully harness the power of light for use in optical devices, it is necessary to understand photons - the fundamental unit of light. Achieving such understanding, however, is easier said than done. That's ...
3,000 atoms entangled with a single photon
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, repres ...
First glimpse inside a macroscopic quantum state
In a recent study published in Physical Review Letters, the research group led by ICREA Prof at ICFO Morgan Mitchell has detected, for the first time, entanglement among individual photon pairs in a beam ...
Popper's experiment realized again—but what does it mean?
Physicists find that entanglement concentration is irreversible, in contrast with previous research
Of Einstein and entanglement: Quantum erasure deconstructs wave-particle duality
Spatial order increases cooperation in quantum prisoner's dilemma game
Entanglement between particle and wave-like states of light resembles Schrodinger's cat experiment (Update)
Quantum teleportation performed with light from a quantum dot embedded in an LED
Space-based experiment could test gravity's effects on quantum entanglement
Quantum sensor's advantages survive entanglement breakdown
The extraordinary promise of quantum information processing—solving problems that classical computers can't, perfectly secure communication—depends on a phenomenon called "entanglement," in which the ...
