Multi-particle entanglement manipulation under positive partial transpose preserving operations
Satoshi Ishizaka, Martin B. Plenio
We consider the transformation of multi-partite states in the single copy setting under positive-partial-transpose-preserving operations (PPT-operations) and obtain both qualitativ…
Classical simulatability, entanglement breaking, and quantum computation thresholds
S. Virmani, Susana F. Huelga, Martin B. Plenio
We investigate the amount of noise required to turn a universal quantum gate set into one that can be efficiently modelled classically. This question is useful for providing upper…
Broken Promises and Quantum Algorithms
Adam Brazier, Martin B. Plenio
In the black-box model, problems constrained by a `promise' are the only ones that admit a quantum exponential speedup over the best classical algorithm in terms of query complexit…
Robust creation of entanglement between ions in spatially separate cavities
D. E. Browne, M. B. Plenio, S. F. Huelga
We present a protocol that allows the generation of a maximally entangled state between individual atoms held in spatially separate cavities. Assuming perfect detectors and neglect…
Entanglement transformations of pure Gaussian states
G. Giedke, J. Eisert, J. I. Cirac +1
We present a theory of entanglement transformations of Gaussian pure states with local Gaussian operations and classical communication. This is the experimentally accessible set of…
Construction of extremal local positive operator-valued measures under symmetry
S. Virmani, M. B. Plenio
We study the local implementation of POVMs when we require only the faithful reproduction of the statistics of the measurement outcomes for all initial states. We first demonstrate…
