Critical timescales for chiral state conversion and irreversibility
Giorgos Pappas, Diego Bautista Avilés, Luis E. F. Foa Torres +1
Non-Hermitian systems driven along slow parametric loops undergo non-adiabatic transitions whose outcome depends sensitively on the driving speed, yet no explicit formula has been…
Precision-Induced Irreversibility in non-Hermitian systems
Luis E. F. Foa Torres, G. Pappas, V. Achilleos +1
Non-Hermitian evolution is mathematically invertible, yet finite dynamic range imposes a sharp operational limit on reversibility. We identify Precision-Induced Irreversibility (PI…
A non-Hermitian loop for a quantum measurement
Luis E. F. Foa Torres, Stephan Roche
Here we present a non-Hermitian framework for modeling state-vector collapse under unified dynamics described by Schrödinger's equation. Under the premise of non-Hermitian Hamilton…
Transport of non-classical light mediated by topological domain walls in a SSH photonic lattice
Gabriel O'Ryan, Joaquín Medina Dueñas, Diego Guzmán-Silva +2
Advancements in photonics technologies have significantly enhanced their capability to facilitate experiments involving quantum light, even at room temperature. Nevertheless, fully…
Quadrature protection of squeezed states in a one-dimensional photonic topological insulator
J. Medina Dueñas, G. O'Ryan Pérez, Carla Hermann-Avigliano +1
What is the role of topology in the propagation of quantum light in photonic lattices? We address this question by studying the propagation of squeezed states in a topological one-…
Towards a time-reversal mirror for quantum systems
Horacio M. Pastawski, Ernesto P. Danieli, Hernan L. Calvo +1
The reversion of the time evolution of a quantum state can be achieved by changing the sign of the Hamiltonian as in the polarization echo experiment in NMR. In this work we descri…
