Resource Type: conference paper
Identifier: http://hdl.handle.net/1959.14/304503
Description: Satellites offer the means to extend quantum communication and quantum key distribution towards global distances. We will outline the proposed QEYSSat mission proposal, which involves a quantum receiv ... More

Identifier: http://hdl.handle.net/1959.14/1192698
Description: We propose an experiment to test the effects of gravity and acceleration on quantum entanglement in space-based setups. We show that the entanglement between excitations of two Bose–Einstein condensat ... More

Identifier: http://hdl.handle.net/1959.14/47717
Description: We address the problem of generating a robust entangling gate between electronic and nuclear spins in a system of a single nitrogen-vacancy center coupled to a nearest ¹³C atom in diamond against cert ... More

Identifier: http://hdl.handle.net/1959.14/44501
Description: Maps that are not completely positive (CP) are often useful to describe the dynamics of open systems. An apparent violation of complete positivity can occur because there are prior correlations of the ... More

Identifier: http://hdl.handle.net/1959.14/42218
Description: A general method for implementing multipartite unitary operations that are close to the identity using a small amount of entanglement and classical communication is presented. For cases where methods ... More

Subject Keyword: teleportation | quantum entanglement
Language: eng
Resource Type: journal article
Identifier: http://hdl.handle.net/1959.14/39680
Description: We analyze quantum teleportation for composite systems, specifically for concatenated teleporation (decomposing a large composite state into smaller states of dimension commensurate with the channel) ... More
