Family of analytic entanglement monotones
A. Delgado, T. Tessier
We derive a family of entanglement monotones, one member of which turns out to be the negativity. Two others are shown to be lower bounds on the I-concurrence, and on the I-tangle,…
Universal Sets of Quantum Gates for Detected Jump-Error Correcting Quantum Codes
G. Alber, M. Mussinger, A. Delgado
A universal set of quantum gates is constructed for the recently developed jump-error correcting quantum codes. These quantum codes are capable of correcting errors arising from th…
Estimation of quantum channels with finite resources
Markus A. Cirone, Aldo Delgado, Dietmar G. Fischer +3
We investigate the problem of determining the parameters that describe a quantum channel. It is assumed that the users of the channel have at best only partial knowledge of it and…
Generalized quantum XOR-gate for quantum teleportation and state purification in arbitrary dimensional Hilbert spaces
Gernot Alber, Aldo Delgado, Nicolas Gisin +1
A generalization of the quantum XOR-gate is presented which operates in arbitrary dimensional Hilbert spaces. Together with one-particle Fourier transforms this gate is capable of…
Optimal universal two-particle entanglement processes in arbitrary dimensional Hilbert spaces
G. Alber, A. Delgado, I. Jex
Universal two-particle entanglement processes are analyzed in arbitrary dimensional Hilbert spaces. On the basis of this analysis the class of possible optimal universal entangleme…
