An Elementary Characterization of Bargmann Invariants
Sagar Silva Pratapsi, João Gouveia, Leonardo Novo +1
Bargmann invariants, also known as multivariate traces of quantum states , are unitary invariant quantities used to characterize weak values,…
Quantum speed limit for Kirkwood-Dirac quasiprobabilities
Sagar Silva Pratapsi, Sebastian Deffner, Stefano Gherardini
What is the minimal time until a quantum system can exhibit genuine quantum features? To answer this question we derive quantum speed limits for two-time correlation functions aris…
Improving fidelity of multi-qubit gates using hardware-level pulse parallelization
Sagar Silva Pratapsi, Diogo Cruz
Quantum computation holds the promise of solving computational problems which are believed to be classically intractable. However, in practice, quantum devices are still limited by…
Competition of decoherence and quantum speed limits for quantum-gate fidelity in the Jaynes-Cummings model
Sagar Silva Pratapsi, Lorenzo Buffoni, Stefano Gherardini
Quantum computers are operated by external driving fields, such as lasers, microwaves or transmission lines, that execute logical operations on multi-qubit registers, leaving the s…
