Decimation technique for open quantum systems: A case study with driven-dissipative bosonic chains

Marcelo Castellanos2023-02-21T13:36:50+01:00Tags: Atomic, Molecular & Chemical. , Optics; Physics|

Authors: Gomez-Leon, Alvaro; Ramos, Tomas; Porras, Diego; Gonzalez-Tudela, Alejandro Journal: PHYSICAL REVIEW A Publication date: 2022/05/26 DOI: 10.1103/PhysRevA.105.052223 Abstract: The unavoidable coupling of quantum systems to external degrees of freedom leads to dissipative (nonunitary) dynamics, which can be radically different from closed-system scenarios. Such open quantum system dynamics is generally described by Lindblad master equations, [...]

Authors: Gomez-Leon, Alvaro; Luis, Fernando; Zueco, David Journal: PHYSICAL REVIEW APPLIED Publication date: 2022/06/14 DOI: 10.1103/PhysRevApplied.17.064030 Abstract: We study the physics of a magnetic molecule described by a ???giant??? spin with multiple (d > 2) spin states interacting with the quantized cavity field produced by a superconducting resonator. By means of the input-output formalism, we [...]

Critical quantum metrology with fully-connected models: from Heisenberg to Kibble-Zurek scaling

Marcelo Castellanos2023-02-21T13:36:47+01:00Tags: Multidisciplinary. , Quantum Science & Technology; Physics|

Authors: Garbe, Louis; Abah, Obinna; Felicetti, Simone; Puebla, Ricardo Journal: QUANTUM SCIENCE AND TECHNOLOGY Publication date: 2022/06/15 DOI: 10.1088/2058-9565/ac6ca5 Abstract: Phase transitions represent a compelling tool for classical and quantum sensing applications. It has been demonstrated that quantum sensors can in principle saturate the Heisenberg scaling, the ultimate precision bound allowed by quantum mechanics, in [...]

Complete Physical Characterization of Quantum Nondemolition Measurements via Tomography
