Subtle Nuances between Quantum and Classical regimes
Karin Wittmann Wilsmann, Erick R. Castro, Itzhak Roditi +2
This study explores the semiclassical limit of an integrable-chaotic bosonic many-body quantum system, providing nuanced insights into its behavior. We examine classical-quantum co…
From integrability to chaos: the quantum-classical correspondence in a triple well bosonic model
Erick R. Castro, Karin Wittmann W., Jorge Chávez-Carlos +3
In this work, we investigate the semiclassical limit of a simple bosonic quantum many-body system exhibiting both integrable and chaotic behavior. A classical Hamiltonian is derive…
Probing Mermin's inequalities violations through pseudospin operators
Philipe De Fabritiis, Itzhak Roditi, Silvio P. Sorella
The violation of Mermin's inequalities is analyzed by making use of two different Bell setups built with pseudospin operators. Employing entangled states defined by means of squeez…
Implementation of a two-stroke quantum heat engine with a collisional model
Filipe V. Melo, Nahum Sá, Ithzak Roditi +4
We put forth a quantum simulation of a stroboscopic two-stroke thermal engine in the IBMQ processor. The system consists of a quantum spin chain connected to two baths at their bou…
Towards solving the BCS Hamiltonian gap in Near-Term Quantum Computers
Nahum Sá, Ivan S. Oliveira, Itzhak Roditi
In this work, using a NISQ framework, we obtain the gap of a BCS Hamiltonian. This could lead to interesting implications for superconductivity research. For such task, we choose t…
An Application of Quantum Annealing Computing to Seismic Inversion
Alexandre M. Souza, Eldues O. Martins, Itzhak Roditi +3
Quantum computing, along with quantum metrology and quantum communication, are disruptive technologies that promise, in the near future, to impact different sectors of academic res…
