Quantum noise stream ciphers utilise the inherent randomness of quantum noise in optical systems to secure data transmission at the physical layer. By embedding cryptographic keys into fluctuations ...
For quantum computers to function, they must be kept at extremely low temperatures. However, today's cooling systems also generate noise that interferes with the fragile quantum information they are ...
A mixer stage has a noise figure of 20 dB. This mixer stage is preceded by an amplifier which has a noise figure of 9 dB and an available power gain of 15 dB. Solve for the the overall noise figure ...
