Elementary gates for quantum computation
... Here we derive a series of results that provide tools for the building up of unitary transformations from simple gates. We build on other recent results that simplify and extend Deutsch's original discovery [24] of a three-bit universal quantum logic gate. As a consequence of the greater power of qu ...

Quantum dynamics in strong fluctuating fields - Physik Uni
... quantum dynamics has been investigated in [68, 82, 83, 85–87]. Other related work has been done at the same time and in parallel by several other research groups elaborating similar [88–90], or different [84, 91–97] approaches which reconcile within some approximations [3, 4, 87, 98, 99].

REDUCED AND EXTENDED WEAK COUPLING LIMIT
... In Sections 3 we recall some facts about completely positive maps and semigroups, sketching proofs of the Stinespring dilation theorem [St] and of the so-called Lindblad form of the generator of a c.p. semigroup [Li, GKS]. In particular, we discuss the freedom of choosing various terms in the Lindbl ...

Quantum Correlations in Information Theory
... quantum entanglement, i.e. peculiar correlations described by quantum laws which are shared, for example, between the sender and the receiver of a message. However, it has been recently shown that entanglement is not the most general form of quantum correlations. Even unentangled states of compound ...

However, we must warn the reader that the intrisinsic losses in the superconducting material do not exhaust, by far, sources of dissipation, even if very high quality factors have been demonstrated in ...
