Single and Entangled Photon Sources
This paper explores the fundamentals and applications of single and entangled photon sources. These sources are the ground works for advances in quantum communications, ranging from quantum cryptography to topics as peculiar as quantum teleportation. Single Photon Sources I. What is a Single Photon Source? A single photon source is an emitter of light that has all of its photons separated in ti...
متن کاملSingle and Entangled Photon Sources
The possibility of totally secure communication through the application of quantum mechanical properties was introduced in 1984 by Bennett and Brassard in their paper, “Quantum Cryptography: Public Key Distribution and Coin Tossing”. As Bennett and Brassard outlined, quantum communication makes it impossible for an eavesdropper to intercept a message without detection by the desired parties. Th...
متن کاملResonant-Cavity-Enhanced Single Photon Avalanche Diodes
We present a resonant-cavity-enhanced Single Photon Avalanche Diode (SPAD) fabricated on a reflecting siliconon-insulator (SOI) substrate. The substrate incorporates a two period distributed Bragg reflector fabricated using a commercially available double-SOI process. The resonant-cavity-enhanced (RCE) SPAD detectors have peak photon detection efficiencies ranging from 41% at 780nm to 32% at 85...
متن کاملDynamically reconfigurable directionality of plasmon-based single photon sources
We propose a plasmon-based reconfigurable antenna to controllably distribute emission from single quantum emitters in spatially separated channels. Our calculations show that crossed particle arrays can split the stream of photons from a single emitter into multiple narrow beams. We predict that beams can be switched on and off by switching host refractive index. The design method is based on e...
