Quantum steering with positive operator valued measures
H. Chau Nguyen, Antony Milne, Thanh Vu +1
We address the problem of quantum nonlocality with positive operator valued measures (POVM) in the context of Einstein-Podolsky-Rosen quantum steering. We show that, given a candid…
Markovian evolution of quantum coherence under symmetric dynamics
Matteo Lostaglio, Kamil Korzekwa, Antony Milne
Both conservation laws and practical restrictions impose symmetry constraints on the dynamics of open quantum systems. In the case of time-translation symmetry, which arises natura…
Efficient detection of useful long-range entanglement in imperfect cluster states
Thomas Nutz, Antony Milne, Pete Shadbolt +1
Photonic cluster states are a crucial resource for optical quantum computing. Recently a quantum dot single photon source has been demonstrated to produce strings of photons in a l…
Volume monogamy of quantum steering ellipsoids for multi-qubit systems
Shuming Cheng, Antony Milne, Michael J. W. Hall +1
The quantum steering ellipsoid can be used to visualise two-qubit states, and thus provides a generalisation of the Bloch picture for the single qubit. Recently, a monogamy relatio…
