Training quantum measurement devices to discriminate unknown non-orthogonal quantum states
D. Concha, L. Pereira, L. Zambrano +1
Here, we study the problem of decoding information transmitted through unknown quantum states. We assume that Alice encodes an alphabet into a set of orthogonal quantum states, whi…
Variational determination of multi-qubit geometrical entanglement in NISQ computers
A. D. Muñoz-Moller, L. Pereira, L. Zambrano +2
Current noise levels in physical realizations of qubits and quantum operations limit the applicability of conventional methods to characterize entanglement. In this adverse scenari…
Complete physical characterization of QND measurements via tomography
L. Pereira, J. J. García-Ripoll, T. Ramos
We introduce a self-consistent tomography for arbitrary quantum non-demolition (QND) detectors. Based on this, we build a complete physical characterization of the detector, includ…
Scalable estimation of pure multi-qubit states
L. Pereira, L. Zambrano, A. Delgado
We introduce an inductive -qubit pure-state estimation method. This is based on projective measurements on states of separable bases or entangled bases plus the compu…
