Time-delayed collective dynamics in waveguide QED and bosonic quantum networks
Carlos Barahona-Pascual, Hong Jiang, Alan C. Santos +1
This work introduces a theoretical framework to model the collective dynamics of quantum emitters in highly non-Markovian environments, interacting through the exchange of photons…
Enhanced Quantum Mpemba Effect with Squeezed Thermal Reservoirs
J. Furtado, Alan C. Santos
The phenomenon where a quantum system can be exponentially accelerated to its stationary state has been referred to as the Quantum Mpemba Effect (QMpE). Due to its analogy with the…
Scalable quantum eraser for superconducting integrated circuits
Ciro Micheletti Diniz, Celso J. Villas Bôas, Alan C. Santos
A fast and scalable scheme for multi-qubit resetting in superconducting quantum processors is proposed by exploiting the feasibility of frequency-tunable transmon qubits and transm…
Validity condition for high-fidelity Digitized Quantum Annealing
Alan C. Santos
Digitizing an adiabatic evolution is a strategy able to combine the good performance of gate-based quantum processors with the advantages of adiabatic algorithms, providing then a…
Quantum battery supercharging via counter-diabatic dynamics
L. F. C. de Moraes, Alan C. Duriez, A. Saguia +2
We introduce a counter-diabatic approach for deriving Hamiltonians modeling superchargable quantum batteries (QBs). A necessary requirement for the supercharging process is the exi…
Stable collective charging of ultracold atoms quantum batteries
Abel Rojo-Francà s, Felipe Isaule, Alan C. Santos +2
We propose a novel quantum battery realized with a few interacting particles in a three-well system with different on-site energies, which could be realized with ultracold atom pla…
