Characterization of Distillable and Activable States using Entanglement Witnesses
B. Kraus, M. Lewenstein, J. I. Cirac
We introduce a formalism that connections entanglement witnesses and the distillation and activation properties of a state. We apply this formalism to two cases: First, we rederive…
Optimal cloning for two pairs of orthogonal states
Dagmar Bruss, Chiara Macchiavello
We study the optimal cloning transformation for two pairs of orthogonal states of two-dimensional quantum systems, and derive the corresponding optimal fidelities.
Reflections upon separability and distillability
D. Bruss, J. I. Cirac, P. Horodecki +4
We present an abstract formulation of the so-called Innsbruck-Hannover programme that investigates quantum correlations and entanglement in terms of convex sets. We present a unifi…
Characterizing Entanglement
Dagmar Bruss
Quantum entanglement is at the heart of many tasks in quantum information. Apart from simple cases (low dimensions, few particles, pure states), however, the mathematical structure…
Teleportation implementation of non-deterministic quantum logic operations by using linear optical elements
XuBo Zou, K. Pahlke, W. Mathis
We present a feasible scheme to implement the non-deterministic quantum logic operation of Knill, Laflamme and Milburn (Nature, 409, 46-52(2001)) by using a teleportation protocol,…
The feasible generation of entangled photon states by using linear optical elements
XuBo Zou, K. Pahlke, W. Mathis
We present a feasible scheme to produce a polarization-entangled photon states in a controllable way. This scheme requires single-photon sources…
