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…
Quantum coherence of steered states
Xueyuan Hu, Antony Milne, Boyang Zhang +1
Lying at the heart of quantum mechanics, coherence has recently been studied as a key resource in quantum information theory. Quantum steering, a fundamental notion originally cons…
Geometric representation of two-qubit entanglement witnesses
Antony Milne, David Jennings, Terry Rudolph
Any two-qubit state can be represented geometrically by a steering ellipsoid inside the Bloch sphere. We extend this approach to represent any block positive two-qubit operator …
Quantum correlations of two-qubit states with one maximally mixed marginal
Antony Milne, David Jennings, Sania Jevtic +1
We investigate the entanglement, CHSH nonlocality, fully entangled fraction and symmetric extendibility of two-qubit states that have a single maximally mixed marginal. Within this…
Quantum steering ellipsoids, extremal physical states and monogamy
Antony Milne, Sania Jevtic, David Jennings +2
Any two-qubit state can be faithfully represented by a steering ellipsoid inside the Bloch sphere, but not every ellipsoid inside the Bloch sphere corresponds to a two-qubit state.…
