Abstract The performance analysis of a quantum random number generator (QRNG), operating based on the interarrival time differences between consecutive photon detections from a coherent light source, is presented. The proposed analysis approach accur

Vehicle-to-Vehicle (V2V) Communication is one of the most promising application opportunities of Visible Light Communication (VLC). This paper suggests a novel transmission technique for VLC-V2V applications, called 2x2 Differential Transmission (2x2

Polarization effects of channels such as turbulent free space and optical fibers can deteriorate the quality of polarization-sensitive communication schemes, for example, quantum key distribution. The exact nature of the channel is problematic to det

We report the sampling rate dependency of a single-bit quantum random number generation scheme using a filtered and amplified source of amplified spontaneous emission (ASE). The quality of randomness is measured by the number of passed NIST statistic

Vertical-cavity surface-emitting lasers (VCSELs) have multiple beneficial properties in quantum key distribution (QKD). However, polarization switching (PS), which happens between two orthogonally polarized eigenmodes, is characteristic of these lase

In the BB84 quantum key distribution (QKD) protocol, the communicating parties do a quantum bit error rate (QBER) test to determine whether there is an eavesdropper trying to gain information about the secret key. However, the QBER is not only influe

A quantum random number generation method based on measuring the time differences between photon detections is analyzed mathematically in terms of bit generation efficiency and bit generation rate. It was found that these two values cannot be maximiz
