How energy conservation limits our measurements
Miguel Navascues, Sandu Popescu
Observations in Quantum Mechanics are subject to complex restrictions arising from the principle of energy conservation. Determining such restrictions, however, has been so far an…
Robust Self Testing of Unknown Quantum Systems into Any Entangled Two-Qubit States
Tzyh Haur Yang, Miguel Navascues
Self testing is a device independent approach to estimate the state and measurement operators, without the need to assume the dimension of our quantum system. In this paper, we sho…
Dimension witnesses and quantum state discrimination
Nicolas Brunner, Miguel Navascués, Tamás Vértesi
Dimension witnesses allow one to test the dimension of an unknown physical system in a device-independent manner, that is, without placing assumptions about the functioning of the…
Joint system quantum descriptions arising from local quantumness
Tom Cooney, Marius Junge, Miguel Navascues +2
Bipartite correlations generated by non-signalling physical systems that admit a finite-dimensional local quantum description cannot exceed the quantum limits, i.e., they can alway…
Quantum Steering and Space-Like Separation
Miguel Navascues, David Perez-Garcia
In non-relativistic quantum mechanics, measurements performed by separate observers are modeled via tensor products. In Algebraic Quantum Field Theory, though, local observables co…
A paradox in bosonic energy computations via semidefinite programming relaxations
M. Navascues, A. Garcia-Saez, A. Acin +2
We show that the recent hierarchy of semidefinite programming relaxations based on non-commutative polynomial optimization and reduced density matrix variational methods exhibits a…
