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 …

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 …

Deterministic two-photon controlled- <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>Z</mml:mi> </mml:math> gate with the two-photon quantum Rabi model

2025 · Physical Review A

We propose a scheme for realizing a deterministic two-photon controlled-$Z$ (cz) gate based on variants of the two-photon quantum Rabi model, which is feasible within the framework of circuit QED. We begin by utilizing the …
