Sentences with phrase «photon pairs»
"Photon pairs" refers to two individual particles of light, known as photons, that are generated or exist together. They are closely linked and connected, behaving in a coordinated way, even when separated by long distances. It's like having two identical twins of light that always interact with each other.

The source creates a stream of photon pairs through a common process in which a laser beam stimulates a special type of crystal.
PHOTON PAIRS Laser light in water (shown) exhibits an unexpected quirk: Light particles interact with their companions in the same way electrons pair up in superconductors.
Then he wants to demonstrate intercontinental quantum key distribution between stations in China and Austria, which will require holding one half of an entangled photon pair on board until the Austrian ground station appears within view of the satellite.
Using time - correlated photon pairs, we show a reduction in the group velocity of photons in both a Bessel beam and photons in a focused Gaussian beam.
Using the satellite, named Micius after an ancient Chinese philosopher, the researchers beamed intertwined photon pairs down to the cities of Delingha in northern China and Lijiang in southern China.
«New technique can capture images of ultrafast energy - time entangled photon pairs.»
Not only do the experiments prove that the phenomenon of entanglement is strong enough to persist even in experiments that may one day be carried out on a satellite or an accelerated spacecraft, they also suggests quantum mechanical entanglement of photon pairs can be tested while the particles undergo relativistic acceleration — conditions under which attempts to unify quantum mechanics and relativity into an overarching «theory of everything» can be made.
This week in Science, the team reports simultaneously measuring more than 1000 photon pairs.
With the new technique, photon pairs could be separated by 10 kilometers or possibly more, Gisin predicts.
Due to their entanglement, each member of a photon pair has to travel the same distance.
And which kind of measurement to perform on this photon is decided by a random - number generator at the same moment when the photon pairs are created at a distant location, about a mile away, which means that no signal could travel fast enough to influence this.
But frustratingly, with that tightening of the statistics came a drop in the rate of decays to photon pairs, which muddies the waters.
To confirm that the particles were entangled, and that the weird qualities of quantum mechanics held, the researchers used the photon pairs to perform a Bell test (SN: 9/19/15, p. 12), which analyzes correlations between the two particles.
Photon pairs are produced with a source (green point).
Photon pairs are then separated and sent by fiber - optic cable to separate detectors in the distant rooms.
