... As device sizes decrease, the standard mean-field theory for the treatment of electron-electron forces becomes less applicable. Motivated by this fact, effective quantum potentials have been established as a proven way to include quantum-mechanical effects into Monte-Carlo (MC) device simulations. T ...

Eavesdropping of two-way coherent-state quantum cryptography via gaussian quantum cloning machines
... In the case of a noiseless channel between Alice and Bob, the only noise in the whole process is introduced by the heterodyne detection. This measurement can be seen as a further Gaussian additive channel at Bob’s site, which(9) gives a Gaussian noise equal to 1 for each quadrature. Thus, according ...

Fast random number generator based on quantum uncertainty
... Shot noise is caused by the fact that light consists of photons. From the description of coherent states, we know that if we perform multiple measurements, the number of photons in a coherent state will follow a Poissonian distribution. Each measurement will detect a certain number of photons that r ...
