Self-testing in prepare-and-measure scenarios and a robust version of Wigner's theorem
Miguel Navascues, Károly F. Pál, Tamás Vértesi +1
We consider communication scenarios where one party sends quantum states of known dimensionality , prepared with an untrusted apparatus, to another, distant party, who probes th…
Optimisation of time-ordered processes in the finite and asymptotic regime
Mirjam Weilenmann, Costantino Budroni, Miguel Navascues
Many problems in quantum information theory can be formulated as optimizations over the sequential outcomes of dynamical systems subject to unpredictable external influences. Such…
Quantum advantages for transportation tasks: projectiles, rockets and quantum backflow
David Trillo, Thinh P. Le, Miguel Navascues
Consider a scenario where a quantum particle is initially prepared in some bounded region of space and left to propagate freely. After some time, we verify if the particle has reac…
Quantum theory based on real numbers can be experimentally falsified
Marc-Olivier Renou, David Trillo, Mirjam Weilenmann +5
While complex numbers are essential in mathematics, they are not needed to describe physical experiments, expressed in terms of probabilities, hence real numbers. Physics however a…
Quantum Preparation Games
Mirjam Weilenmann, Edgar A. Aguilar, Miguel Navascues
A preparation game is a task whereby a player sequentially sends a number of quantum states to a referee, who probes each of them and announces the measurement result. The measurem…
Entanglement marginal problems
Miguel Navascues, Flavio Baccari, Antonio Acin
We consider the entanglement marginal problem, which consists of deciding whether a number of reduced density matrices are compatible with an overall separable quantum state. To ta…
