Digital-analog quantum computation aims to reduce the currently infeasible resource requirements needed for near-term quantum information processing by replacing a series of two-qubit gates with a unitary transformation generated by the systems underlying Hamiltonian. Inspired by this paradigm, we consider superconducting architectures and extend the cross-resonance effect, up to first order in perturbation theory, from a pair of qubits to 1D chains and 2D square lattices. In an appropriate…

Floquet Engineering Heisenberg from Ising Using Constant Drive Fields for Quantum Simulation
The time-evolution of an Ising model with large driving fields over discrete time intervals is shown to be reproduced by an effective XXZ-Heisenberg model at leading order in the inverse field
Fourier-based quantum signal processing
TLDR
An algorithm for Hermitian-operator function design from an oracle given by the unitary evolution with respect to that operator at a fixed time is presented, which implements a Fourier approximation of the target function based on the iteration of a basic sequence of single-qubit gates, for which it is proved the expressibility.

We propose a quantum protocol that allows preparing a ground state (GS) of the honeycomb Kitaev model. Our approach efficiently uses underlying symmetries and techniques from topological error
Noise in Digital and Digital-Analog Quantum Computation
TLDR
A careful comparison between digital and digital-analog paradigms under the presence of noise sources shows that, when the different noise channels usually present in superconducting quantum processors are considered, the fidelity of the QFT algorithm for thedigital-an analog paradigm outperforms the one obtained for the digital approach.
