Transmission Estimation at the Fundamental Quantum Cramér-Rao Bound with Macroscopic Quantum Light
Timothy S. Woodworth, Carla Hermann-Avigliano, Kam Wai Clifford Chan +1
The field of quantum metrology seeks to apply quantum techniques and/or resources to classical sensing approaches with the goal of enhancing the precision in the estimation of a pa…
Emergence of Non-Gaussian Coherent States Through Nonlinear Interactions
M. Uria, A. Maldonado-Trapp, C. Hermann-Avigliano +1
Light-matter interactions that are nonlinear with respect to the photon number reveal the true quantum nature of coherent states. We characterize how coherent states depart from Ga…
Collective enhancement in dissipative quantum batteries
Javier Carrasco, Jerónimo R. Maze, Carla Hermann-Avigliano +1
We study a quantum battery made out of non-mutually interacting qubits coupled to a dissipative single electromagnetic field mode in a resonator. We quantify the charging energ…
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-…
Transmission Estimation at the Cramér-Rao Bound for Squeezed States of Light in the Presence of Loss and Imperfect Detection
Timothy S. Woodworth, Kam Wai Clifford Chan, Carla Hermann-Avigliano +1
Enhancing the precision of a measurement requires maximizing the information that can be gained about the quantity of interest from probing a system. For optical based measurements…
Deterministic Generation of Large Fock States
M. Uria, P. Solano, C. Hermann-Avigliano
We present a protocol to deterministically prepare the electromagnetic field in a large photon number state. The field starts in a coherent state and, through resonant interaction…
Manipulation of Multimode Squeezing in a Coupled Waveguide Array
S. Rojas-Rojas, E. Barriga, C. Muñoz +2
We present a scheme for generating and manipulating three-mode squeezed states with genuine tripartite entanglement by injecting single-mode squeezed light into an array of coupled…
Phase sensing beyond the standard quantum limit with a truncated SU(1,1) interferometer
Brian E. Anderson, Prasoon Gupta, Bonnie L. Schmittberger +4
An SU(1,1) interferometer replaces the beamsplitters in a Mach-Zehnder interferometer with nonlinear interactions and offers the potential of achieving high phase sensitivity in ap…
Petal-shape probability areas: complete quantum state discrimination
Luis Roa, Carla Hermann-Avigliano, Roberto Salazar +3
We find the allowed complex numbers associated with the inner product of N equally separated pure quantum states. The allowed areas on the unitary complex plane have the form of pe…
