Catching a flying photon

Quantum Optics Single photons are ideal carriers of quantum information because they are fast, robust, and capable of traveling long distances. An interconnected quantum network, however, will require these information carriers to be stored and processed at node points, or memories. Much effort is

Routing one photon with a few others

Quantum Optics Single particles of light, photons, are ideal carriers of quantum information because they can travel far and fast and don't interact much with each other. However, this behavior has hampered attempts to control the propagation of single photons using all-optical setups. Shomroni et

Noise affecting photon pair generation in silicon wire waveguide

Stéphane Clemmen, Arthur Perret, Wim Bogaerts +1 more

Abstract: We study quantitatively the weak source of noise that is presentwhen correlated photons are produced via four wave mixing in siliconnanophotonic waveguides. First, we deduce the amont of noise from thedependance of the photon flux on the pump power. Second we cara cterisethe spectrum of the noise and of the pairs of photons which shows that thenoise is due to a scattering of photons by a thermal bath. Third we show thatthe photon flux (noise plus pairs) is essentially instantane ous, and cannottherefore be attributed to carrier induced effects. We discuss our results andcompare them to photon pair generation in silica fibers. © 2011 Optical Society of America OCIS codes: (270.0270) Quantum optics; (270.2500) Quantum optics, Fluctuations, relax-ations, and noise; (190.3270) Nonlinear optics, Ker effect; (190.5650) Nonlinear optics, Ramanscattering References and links 1.

To catch a photon nondestructively

I. S. Osborne

Quantum Optics With several techniques now available for generating single photons, coupled with their relative robustness and ability to be transmitted long distances, photons are ideal carriers of quantum information. However, determining the best methodol-ogy for detecting a single propagating photon without absorbing it (and destroying it) remains a work in progress. Xia et al. propose a cavity-free approach based on an induced nonlinear interaction. By co-propagating a weak probe beam with the signal beam containing the single photon in a nonlinear medium, they show theoretically that the phase of the probe beam should be shifted, conditional on the presence of the single photon. The proposed technique could offer a simpler route for implementing such quantum non-demolition detection strategies necessary for successful quantum information processing. Phys. Rev. Lett. 116 , 023601 (2016).
