Advances in the quantum-state texture theory
Jose Alfredo de Leon, Miguel Gonzalez, Alejandro Fonseca +2
The recently introduced concept of quantum-state texture (QST) has found applications ranging from the identification of unknown quantum gates to the study of quantum phase transit…
Measuring unitary invariants with the quantum switch
Pedro C. Azado, Rafael Wagner, Rui S. Barbosa +1
Bargmann invariants, multivariate traces of states, completely characterize any unitary-invariant property of a set of states. Unitary invariants enable the description of quantum…
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…
Optimal complexity of parameterized quantum circuits
Guilherme Ilário Correr, Pedro C. Azado, Diogo O. Soares-Pinto +1
Parameterized quantum circuits play a key role for the development of quantum variational algorithms in the realm of the NISQ era. Knowing their actual capability of performing dif…
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…
