  Shot Noise for 1550 nm Laser using Balanced Homodyne Detection

  By Shikhar Singh

  Abstract: AbstractSingle photon detectors are indispensable for secure communication in quantum cryptography. Shot noise, a fundamental limit to photodetection occurs due to discreteness of photons. Shot noise plays an important role in telecommunications and optical science because of its property of setting a practical limit to the signal-to-noise ratios. In order to implement BB84 protocol, there is a need to assess appropriate lower bound on experimental errors caused during secure key …
