Single- & Entangled Photon Sources:
We are working on nonclassical light sources:
- sources of single photons exhibiting antibunching (separation of all photons in time), and
- entangled photon sources.
Their applications are secure quantum communication, quantum metrology, fundamental physics experiments, and student education. Entanglement is also a key concept in quantum computing.
For first reading about single and entangled photon sources, their preparation and practical use see review paper S.G. Lukishova, "Single photon sources for secure quantum communication", Proceedings SPIE 9065, Fundamentals of Laser-Assisted Micro- and Nanotechnologies 2013, 90650C (November 28, 2013).
