Large Quantum Delocalization of a Levitated Nanoparticle Using Optimal Control: Applications for Force Sensing and Entangling via Weak Forces

2022-04-05T17:41:00+02:00Tags: , |

Authors: Weiss, T.; Roda-Llordes, M.; Torrontegui, E.; Aspelmeyer, M.; Romero-Isart, O. Journal: PHYSICAL REVIEW LETTERS Publication date: 2021/07/07 DOI: 10.1103/PhysRevLett.127.023601 Abstract: We propose to optimally control the harmonic potential of a levitated nanoparticle to quantum delocalize its center-of-mass motional state to a length scale orders of magnitude larger than the quantum zero-point motion. Using a [...]

On the Relationship between Hydrogen Bond Strength and the Formation Energy in Resonance-Assisted Hydrogen Bonds

2022-04-05T17:41:01+02:00Tags: , |

Authors: Manuel Guevara-Vela, Jose; Gallegos, Miguel; Valentin-Rodriguez, Monica A.; Costales, Aurora; Rocha-Rinza, Tomas; Martin Pendas, Angel Journal: MOLECULES Publication date: 2021/07/01 DOI: 10.3390/molecules26144196 Abstract: Resonance-assisted hydrogen bonds (RAHB) are intramolecular contacts that are characterised by being particularly energetic. This fact is often attributed to the delocalisation of pi electrons in the system. In the present [...]

Authors: Koner, Debasish; Barrios, Lizandra; Gonzalez-Lezana, Tomas; Panda, Aditya N. Journal: MOLECULES Publication date: 2021/07/01 DOI: 10.3390/molecules26144206 Abstract: The study of the dynamics of atom-diatom reactions involving two rare gas (Rg) atoms and protons is of crucial importance given the astrophysical relevance of these processes. In a series of previous studies, we have been investigating [...]

Hybrid quantum-classical optimization with cardinality constraints and applications to finance

2022-04-05T17:41:01+02:00Tags: , |

Authors: Fernandez-Lorenzo, Samuel; Porras, Diego; Garcia-Ripoll, Juan Jose Journal: QUANTUM SCIENCE AND TECHNOLOGY Publication date: 2021/07/01 DOI: 10.1088/2058-9565/abf9af Abstract: In this work we develop tools to address combinatorial optimization problems with a cardinality constraint, in which only a subset of variables end up having nonzero values. Firstly, we introduce a new heuristic pruning method that [...]
