Quantum search without entanglement [PDF]
Entanglement of quantum variables is usually thought to be a prerequisite for obtaining quantum speed-ups of information processing tasks such as searching databases.

Heralded entanglement distribution between two absorptive quantum memories [PDF]
Owing to the inevitable loss in communication channels, the distance of entanglement distribution is limited to approximately 100 kilometres on the ground1. Quantum repeaters can circumvent this problem by using quantum memory and entanglement swapping2.

QUANTUM ENTANGLEMENT AND SECRECY
This was a talk given at the International Conference on Fundamental Sciences, Mathematics and Theoretical Physics, 13-17 March 2000. This talk provides a general introduction to the field of cryptography and touches upon the surface of many activities presently being pursued under the heading of quantum cryptography.

Monogamy of Quantum Entanglement
Unlike classical correlation, quantum entanglement cannot be freely shared among many parties. This restricted shareability of entanglement among multi-party systems is known as monogamy of entanglement, which is one of the most fundamental properties of entanglement.

Quantum entanglement on boundaries [PDF]
Quantum entanglement in 3 spatial dimensions is studied in systems with physical boundaries when an entangling surface intersects the boundary. We show that there are universal logarithmic boundary terms in the entanglement R nyi entropy and derive them for different conformal field theories and geometrical configurations. The paper covers such topics

Correcting Quantum Errors with Entanglement [PDF]
We show how entanglement shared between encoder and decoder can simplify the theory of quantum error correction. The entanglement-assisted quantum codes we describe do not require the dual-containing constraint necessary for standard quantum error ...

Entanglement and quantum groups [PDF]
We describe quantum mechanical entanglement in terms of compact quantum groups. We prove an analog of positivity of partial transpose criterion and formulate a Horodecki-type theorem.

Doubling the Size of Quantum Simulators by Entanglement Forging [PDF]
Quantum computers are promising for simulations of chemical and physical systems, but the limited capabilities of today's quantum processors permit only small, and often approximate, simulations.
