Summary: TEHRAN (FNA)- Physicists have created a new form of light that could enable quantum computing with photons.
Physicists Create New Form of Light
Vuletic and Lukin have previously conducted experiments in which they observed photons binding in pairs, and the new experiments were designed to see if they could get more than two photons to interact at the same time.
New Form Of Light Proves Photons Can Interact
Just as Cotler and Wilczek expected, the experimenters couldn't formulate a chronology that was consistent with both the starting and ending measurements of each photon and the mirror-based evidence in between.
Quantum histories get all tangled up: tracing a particle's past can require multiple chronologies
Before we discuss the details of photonic quantum information experiments, here we briefly explain the concept of spontaneous parametric down-conversion (SPDC), the generation of heralded single photons and entangled states, and the various types of photon detectors.
Photonic quantum information: science and technology
You are most familiar with photons with energies of about half a million energy units.
Evidence of cell tower, cancer link is lacking
Data from the planned Cherenkov Telescope Array, a ground-based gamma-ray observatory, and scheduled upgrades to the DESY ALPS particle-physics experiment in Germany, could reveal if photons do change their stripes.
Distant galaxies hint at exotic particle
In the case of ordinary optical communications, the problem of photon loss is easily solved by adding "repeaters" along the line--gadgets that receive weakened laser pulses and replace them with stronger ones.
Welcome to the quantum Internet
He bases this on his equations 7 and 8 in which he ascribes a state to the photon both passing along arm 1 or 2 and arm 5 or 6.

The photon associated with the first term has no circular polarization; this contribution vanishes if |[l.
Radiative neutron [beta]-decay in effective field theory
This switch allows a photon -- the smallest unit of light -- to influence the flow of other photons in the same way that transistors inside a PC control the flow of electrons," says Aephraim Steinberg, physics professor and co-author of a paper published in Physical Review Letters last fall.

Observing a photon directly can destroy such information, making it impossible to simply measure it and communicate the information by ordinary channels.
