Abstract
A key generator system that includes a quantum random number generator (QRNG) to generate a string of ternary digits. The QRNG includes a preparation stage, a universal interferometer to output a measurement outcome, and a detector to detect the measurement outcome and produce a quantum random (QR) ternary digit based on the outcome. The system includes a key generator to receive the string of QR ternary digits and generate a key including binary string of bits produced by mapping pairs of QR ternary digits into bits. The preparation stage includes an arrangement of beamsplitters defined by a selected probability distribution including a probability set of {p1, p2, p3} that adds to 1 and p1, p2 and p3 are rational numbers and less than 1 and greater than zero, and a selected one preparation stage candidate of candidates derived based on a value definite quantum states equation.
