Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

Quantum entanglement links two particles, such as photons, so that measuring one instantly reveals information about the other. Reliable generation and distribution of entangled states are essential ...

Physicists at the University of Stuttgart, Germany have teleported a quantum state between photons generated by two different ...

Quantum entanglement has shifted from a philosophical puzzle to a design brief for engineers working at the scale of atoms, ...

You are watching a long-standing assumption in physics and engineering quietly fall apart. Researchers at Northwestern ...

A further benefit is that the channels can be multiplexed, allowing many quantum processors to access the system at the same ...

A new study takes the GHZ paradox, which describes how quantum theory can't be described by local realistic descriptions, to ...

A recent theoretical study by an international team, which also involves the National Institute of Optics of the National Research Council (Cnr-Ino), proposes an innovative method to generate ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

a When photon-pair generation is probabilistic, a two-photon interference measurement between A2 and B1 alone cannot distinguish successful events from unsuccessful ones. Therefore, additional ...

A team of researchers at the University of Waterloo have made a breakthrough in quantum computing that elegantly bypasses the ...
