Ergotropic and passive contributions on the phase-space information geometry of Gaussian states
Ivan Medina, Camila Raupp, Pedro B. Melo +1
We establish a direct connection between quantum thermodynamics and information geometry by introducing an ergotropic decomposition of the Wigner-Fisher information for Gaussian qu…
Quantum state texture of dynamical criticality
Lucas C. Céleri, Krissia Zawadzki, Ivan Medina +1
We investigate the role of quantum state texture in dynamical quantum phase transitions by establishing a direct connection between critical nonequilibrium dynamics and the recentl…
Thermodynamics of the optical pumping process in Nitrogen-Vacancy centers
Ivan Medina, Sérgio R. Muniz, Elisa I. Goettems +1
The optical pumping process is a fundamental tool for quantum protocols using the electronic and nuclear spins in the Nitrogen-Vacancy (NV) centers platform. In this work, we explo…
Anomalous discharging of quantum batteries: the ergotropic Mpemba effect
Ivan Medina, Oisín Culhane, Felix C. Binder +2
Anomalous thermal relaxation is ubiquitous in nonequilibrium statistical mechanics. An emblematic example of this is the Mpemba effect, where an initially ``hot'' system cools fast…
Expressibility, entangling power and quantum average causal effect for causally indefinite circuits
Pedro C. Azado, Guilherme I. Correr, Alexandre Drinko +3
Parameterized quantum circuits are the core of new technologies such as variational quantum algorithms and quantum machine learning, which makes studying its properties a valuable…
Benchmarking Variational Quantum Eigensolvers for Entanglement Detection in Many-Body Hamiltonian Ground States
Alexandre Drinko, Guilherme I. Correr, Ivan Medina +3
Variational quantum algorithms (VQAs) have emerged in recent years as a promise to obtain quantum advantage. These task-oriented algorithms work in a hybrid loop combining a quantu…
Characterizing randomness in parameterized quantum circuits through expressibility and average entanglement
Guilherme Ilário Correr, Ivan Medina, Pedro C. Azado +2
While scalable error correction schemes and fault tolerant quantum computing seem not to be universally accessible in the near sight, the efforts of many researchers have been dire…
Variational-quantum-eigensolver-inspired optimization for spin-chain work extraction
Ivan Medina, Alexandre Drinko, Guilherme I. Correr +2
The energy extraction from quantum sources is a key task to develop new quantum devices such as quantum batteries (QB). In this context, one of the main figures of merit is the erg…
Transmission losses in optical qubits for controlled teleportation
I. Medina, F. L. Semião
In this work, we investigate the controlled teleportation protocol using optical qubits within the single-rail logic. The protocol makes use of an entangled tripartite state shared…
