Nonclassical light from a large number of independent single-photon emitters

Nonclassical light from a large number of independent single-photon emitters

Nonclassical quantum effects gradually reach domains of physics of large systems previously considered as purely classical. We derive a hierarchy of operational criteria suitable for a reliable detection of nonclassicality of light from an arbitrarily large ensemble of independent single-photon emitters. We show, that such large ensemble can always emit nonclassical light without any phase refe...

Solid-state single-photon emitters

631 Photonic technologies are becoming increasingly prevalent in our daily lives. After decades of rapid advances, light sources — especially lasers and light-emitting diodes — have become high-performance, yet low-cost and reliable components, driving the Internet and lighting cities. A new frontier of research is the development of non-classical light sources: sources that produce streams of ...

Two-photon absorption of nonclassical light.

Photon-assisted tunnelling with nonclassical light

Among the most exciting recent advances in the field of superconducting quantum circuits is the ability to coherently couple microwave photons in low-loss cavities to quantum electronic conductors. These hybrid quantum systems hold great promise for quantum information-processing applications; even more strikingly, they enable exploration of new physical regimes. Here we study theoretically the...

Non-blinking single-photon emitters in silica

Samples for single-emitter spectroscopy are usually prepared by spin-coating a dilute solution of emitters on a microscope cover slip of silicate based glass (such as quartz). Here, we show that both borosilicate glass and quartz contain intrinsic defect colour centres that fluoresce when excited at 532 nm. In a microscope image the defect emission is indistinguishable from spin-coated emitters...
