Complex Field Formulation of the Quantum Estimation Theory
M. Muñoz, L. Pereira, C. Vargas +2
We present a complex field formulation of the quantum estimation theory that works natively with complex statistics on the dependence of complex parameters. This formulation states…

Machine Learning approach to reconstruct Density Matrices from Quantum Marginals
Daniel Uzcategui-Contreras, Antonio Guerra, Sebastian Niklitschek +1
In this work, we propose a machine learning-based approach to address a specific aspect of the Quantum Marginal Problem: reconstructing a global density matrix compatible with a gi…

Minimum optical depth multiport interferometers for approximating arbitrary unitary operations and pure states
Luciano Pereira, Alejandro Rojas, Gustavo Lima +3
Reconfigurable devices which can implement arbitrary unitary operations are crucial for photonic quantum computation, optical neural networks, and boson sampling. Here, we address…
