Quantum learning with a single-atom sensor

Yin Mo, Emilio Bagan, Giulio Chiribella

The ability to gather information and to act upon it is at the core of every learning agent. But what is the impact of quantum mechanics on an agent's ability to sense external inp…

Quantum-Enhanced Zero-Error Communication and Storage under Positional Uncertainty

Arnau Diebra, David González-Lociga, Mark Hillery +2

Permutation channels model communication and storage scenarios in which the positional identity of the physical carriers is partially or completely lost, so that the transmitted in…

Quantum Advantage in Identifying the Parity of Permutations with Certainty

Arnau Diebra, Santiago Llorens, David González-Lociga +4

We establish a sharp quantum advantage in determining the parity (even/odd) of an unknown permutation applied to any number of particles. Classically, this is impossible…

Quantum state exclusion for group-generated ensembles of pure states

Arnau Diebra, Santiago Llorens, Emili Bagan +2

Quantum state exclusion is the task of determining which states from a given set a system was not prepared in. We provide a complete solution to optimal quantum state exclusion for…

Optimal Cloning of Quantum States with a Fixed Failure Rate

E. Bagan, V. Yerokhin, A. Shehu +2

Perfect cloning of a known set of states with arbitrary prior probabilities is possible if we allow the cloner to sometimes fail completely. In the optimal case the probability of…
