Fermionic models with superconducting circuits

2015 · EPJ Quantum Technology

We propose a method for the efficient quantum simulation of fermionic systems with superconducting circuits. It consists in the suitable use of Jordan-Wigner mapping, Trotter decomposition, and multiqubit gates, be with the use of a …

Finite-time quantum correlations of propagating squeezed microwaves

2017 · arXiv (Cornell University)

Two-mode squeezing is a fascinating example of quantum entanglement manifested in cross-correlations of incompatible observables between two subsystems. At the same time, these subsystems themselves may contain no quantum signatures in their self-correlations. These properties …

Probabilistic eigensolver with a trapped-ion quantum processor

2020 · Physical Review A

Preparing the eigenstate, especially the ground state, of a complex Hamiltonian is of great importance in quantum simulations. Many proposals have been introduced and experimentally realized, among which are quantum variational eigensolver and heat-bath algorithmic …

Selective interactions in the quantum Rabi model

2020 · Physical Review A

We demonstrate the emergence of selective $k$-photon interactions in the strong and ultrastrong coupling regimes of the quantum Rabi model with a Stark coupling term. In particular, we show that the interplay between the rotating …

Physics-Informed Neural Networks for an optimal counterdiabatic quantum computation

2023 · arXiv (Cornell University)

We introduce a novel methodology that leverages the strength of Physics-Informed Neural Networks (PINNs) to address the counterdiabatic (CD) protocol in the optimization of quantum circuits comprised of systems with $N_{Q}$ qubits. The primary objective …
