Constrained bounds on measures of entanglement
Animesh Datta, Steven T. Flammia, Anil Shaji +1
Entanglement measures constructed from two positive, but not completely positive maps on density operators are used as constraints in placing bounds on the entanglement of formatio…
Doubly constrained bounds on the entanglement of formation
Animesh Datta, Steven T. Flammia, Anil Shaji +1
We derive bounds on the entanglement of formation of states of a 4xN bipartite system using two entanglement monotones constructed from operational separability criteria. The bound…
On Decoherence in Quantum Clock Synchronization
Sergio Boixo, Carlton M. Caves, Animesh Datta +1
We study two quantum versions of the Eddington clock-synchronization protocol in the presence of decoherence. The first protocol uses maximally entangled states to achieve the Heis…
