Entangled Two-Photon Absorption in Cesium Atoms and the Limitations of the Far-Off-Resonance Approximation
Michael Caracas Núñez, Dario Egloff, Mayerlin Nuñez Portela
The discrepancies between theoretical and experimental results in the process of entangled two-photon absorption (ETPA) are not fully understood. Atomic systems are a promising alt…
Cavity Control of Topological Qubits: Fusion Rule, Anyon Braiding, and Majorana-Schrödinger Cat States
Luis Quiroga, Fernando J. Gómez-Ruiz, Ivan A. Bocanegra-Garay +2
We investigate the effects of coupling a local electromagnetic cavity to a segment of a topological Kitaev chain (KC), with particular emphasis on the interplay between photons and…
Quantum Edge Detection
Santiago Llorens, Walther González, Gael Sentís +3
This paper introduces quantum edge detection, aimed at locating boundaries of quantum domains where all particles share the same pure state. Focusing on the 1D scenario of a string…
Classical Invasive Description of Informationally-Complete Quantum Processes
Moritz F. Richter, Andrea Smirne, Walter T. Strunz +1
In classical stochastic theory, the joint probability distributions of a stochastic process obey by definition the Kolmogorov consistency conditions. Interpreting such a process as…
Experimental validation of the Kibble-Zurek Mechanism on a Digital Quantum Computer
Santiago Higuera-Quintero, Ferney J. Rodríguez, Luis Quiroga +1
The Kibble-Zurek mechanism (KZM) captures the essential physics of nonequilibrium quantum phase transitions with symmetry breaking. KZM predicts a universal scaling power law for t…
Uncertainties in Quantum Measurements: A Quantum Tomography
A. P. Balachandran, F. Calderón, V. P. Nair +3
The observables associated with a quantum system form a non-commutative algebra . It is assumed that a density matrix can be determined from the expectation…
