Efficient classical simulation of cluster state quantum circuits with alternative inputs
Sahar Atallah, Michael Garn, Sania Jevtic +2
We provide new examples of pure entangled systems related to cluster state quantum computation that can be efficiently simulated classically. In cluster state quantum computation i…
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…
Frustration-free Hamiltonians supporting Majorana zero edge modes
Sania Jevtic, Ryan Barnett
A one-dimensional fermionic system, such as a superconducting wire, may host Majorana zero-energy edge modes (MZMs) at its edges when it is in the topological phase. MZMs provide a…
Smallest disentangling state spaces for general entangled bipartite quantum states
Hussain Anwar, Sania Jevtic, Oliver Rudolph +1
Entangled quantum states can be given a separable decomposition if we relax the restriction that the local operators be quantum states. Motivated by the construction of classical s…
Families of pure PEPS with efficiently simulatable local hidden variable models for most measurements
Hussain Anwar, Sania Jevtic, Oliver Rudolph +1
An important problem in quantum information theory is to understand what makes entangled quantum systems non-local or hard to simulate efficiently. In this work we consider situati…
Smallest state spaces for which bipartite entangled quantum states are separable
Hussain Anwar, Sania Jevtic, Oliver Rudolph +1
According to usual definitions, entangled states cannot be given a separable decomposition in terms of products of local density operators. If we relax the requirement that the loc…
How Einstein and/or Schrödinger should have discovered Bell's Theorem in 1936
Sania Jevtic, Terry Rudolph
We show how one can be led from considerations of quantum steering to Bell's theorem. We begin with Einstein's demonstration that, assuming local realism, quantum states must be in…
Einstein-Podolsky-Rosen steering and the steering ellipsoid
Sania Jevtic, Michael J. W. Hall, Malcolm R. Anderson +2
The question of which two-qubit states are steerable (i.e. permit a demonstration of EPR-steering) remains open. Here, a strong necessary condition is obtained for the steerability…
Single-qubit thermometry
Sania Jevtic, David Newman, Terry Rudolph +1
Distinguishing hot from cold is the most primitive form of thermometry. Here we consider how well this task can be performed using a single qubit to distinguish between two differe…
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.…
Quantum Steering Ellipsoids
Sania Jevtic, Matthew F. Pusey, David Jennings +1
The quantum steering ellipsoid of a two-qubit state is the set of Bloch vectors that Bob can collapse Alice's qubit to, considering all possible measurements on his qubit. We provi…
How Einstein and/or Schroedinger should have discovered Bell's theorem in 1936
Terry Rudolph
This note shows how one can be led from considerations of quantum steering to Bell's theorem. The point is that steering remote systems by choosing between two measurements can be…
Exchange Fluctuation Theorem for correlated quantum systems
Sania Jevtic, David Jennings, Terry Rudolph +3
We extend the Exchange Fluctuation Theorem for energy exchange between thermal quantum systems beyond the assumption of molecular chaos, and describe the non-equilibrium exchange d…
Quantum Mutual Information Along Unitary Orbits
Sania Jevtic, David Jennings, Terry Rudolph
Motivated by thermodynamic considerations, we analyse the variation of the quantum mutual information on a unitary orbit of a bipartite system's state, with and without global cons…
Maximally and minimally correlated states attainable within a closed evolving system
Sania Jevtic, David Jennings, Terry Rudolph
The amount of correlation attainable between the components of a quantum system is constrained if the system is closed. We provide some examples, largely from the field of quantum…
