Decoherence of a Quantum Bit Circuit
... a voltage source. Right: schematic circuit. The Josephson coupling allows the exchange of Cooper pairs. The phase of the superconducting island and the number of extra Cooper pairs inside are conjugated variables. The phase qubit[16] developed at NIST (Boulder) consists of a Josephson junction in a ...

Dynamic quantum vacuum and relativity
... On the other hand, 20th century theoretical physics brought the idea of a quantum vacuum as a fundamental medium subtending the observable forms of matter, energy and space-time. As a consequence of quantum field theories and cosmology, the physical vacuum can be regarded as a unified system governi ...

Quantum fluctuation relations: Foundations and applications
... Eq. (2). Bochkov and Kuzovlev (1977, 1979, 1981a, 1981b) proved Eq. (14) for classical systems. Their derivation will be reviewed in the next section. The quantum version, Eq. (55), was not reported until recently (Andrieux and Gaspard, 2008). In Sec. III.C we discuss the fundamental obstacles that ...

Basic Notions of Entropy and Entanglement
... On the other hand, if the indicator is “irreversible” and does not automatically return to its initial setting, we will not get back to the initial state, and we cannot literally repeat the cycle. In this situation, if we have a store of indicators, their values, after use, will constitute a memory. ...
