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…
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…
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…
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…
