Complete disentanglement by partial pure dephasing
Katarzyna Roszak, Pawel Machnikowski
We study the effect of pure dephasing on the entanglement of a pair of two-level subsystems (qubits). We show that partial dephasing induced by a super-Ohmic reservoir, correspondi…
Universality of Measurements on Quantum Markets
Ireneusz Pakula, Edward W. Piotrowski, Jan Sladkowski
We reason about possible future development of quantum game theory and its impact on information processing and the emerging information society. Two of the authors have recently p…
Change of decoherence scenario and appearance of localization due to reservoir anharmonicity
Paweł Machnikowski
Although coupling to a super-Ohmic bosonic reservoir leads only to partial dephasing on short time scales, exponential decay of coherence appears in the Markovian limit (for long t…
On a Stroboscopic Approach to Quantum Tomography of Qudits Governed by Gaussian Semigroups
Andrzej Jamiołkowski
In this paper, we discuss the minimal number of observables, where expectation values at some time instant determine the trajectory of a d-level quantum system ("qudit") governed b…
The Bloch-vector space for N-level systems -- the spherical-coordinate point of view
Gen Kimura, Andrzej Kossakowski
Bloch-vector spaces for -level systems are investigated from the spherical-coordinate point of view in order to understand their geometrical aspects. We show that the maximum ra…
Quantum cryptography with correlated twin laser beams
Constantin V. Usenko, Vladyslav C. Usenko
The data transmission protocol, based on the use of a strongly correlated pair of laser beams, is proposed. The properties of the corresponding states are described in detail. The…
