Recent experiments with detailed control over individual quantum systems have changed the face of quantum physics. These systems include atoms at the low temperatures attained by the 1997 Nobel Laureates, they include entangled photons in cavities, and they include the quantum systems used in new and future technologies like quantum cryptography and quantum computation. The experiments have led to a revival of interest in the foundations of Quantum theoryQuantum theoryIndustrial applicationsQuantum theory.Quantum theoryIndustrial applications.530.12Percival Ian1931-40684MiAaPQMiAaPQMiAaPQBOOK9910780074803321Quantum state diffusion375076UNINA
