Quantum Direct-Sequence Spread-Spectrum CDMA Communication Systems: Mathematical Foundations

Quantum Internet, , , , , , , , ,

Abstract: This article describes the fundamental principles and mathematical foundations of quantum direct-sequence spread-spectrum code division multiple-access communication systems. The evolution of quantum signals through the quantum direct-sequence spread-spectrum multiple-access communication system is carefully characterized by a novel approach called the decomposition of creation operators. In this methodology, the creation operator of the transmitted quantum […]

High-Stability Cryogenic System for Quantum Computing With Compact Packaged Ion Traps

Open Access, Physical Implementations, , , , , ,

Cryogenic environments benefit ion trapping experiments by offering lower motional heating rates, collision energies, and an ultrahigh vacuum (UHV) environment for maintaining long ion chains for extended periods of time. Mechanical vibrations caused by compressors in closed-cycle cryostats can introduce relative motion between the ion and the wavefronts of lasers used to manipulate the ions. […]
