Single photon quantum cryptography

• The fastest (general-purpose) factoring algorithm to date is the number field sieve algorithm of Buhler, Lenstra, and Pomerance. – For d-bit numbers, the running time is

The time evolution of the mean photon number and of the atomic inversion is calculated using, on the one hand, a numerical technique for the quantum dynamics of a small number

For the exciton based source, we add laser photons to the single photon emission from the QDSPS by turning the quarter waveplate (QWP) of the excitation pulse (see Figure 1(a))..

Detection of a single photon generated by the sum- frequency interaction heralds photon subtraction from the multimode squeezed vacua, where the time-frequency mode of the

This Review aims to introduce the technology advances of InGaAs/InP single-photon detector systems in the telecom wavelengths and the relevant quantum communication applications,

It is well-known that informationally-secure bit commitment cannot be obtained in the standard (classical) model and the early success of quantum key distribution raised the hope

If the number of photons n emitted by the atom in a short interval T is counted, then the photon statistic must be sub-poissonian. 1.13 a) is represented the antibunching setup

To conclude, the good properties of GQDs: single-photon emission, brightness, and photostability show that they are very promising materials for applications requiring single
