Multi-purpose quantum laboratories from superconducting circuits
Arpit Arora, Emily M. Been, William Munizzi +4
Superconducting circuits (SCs) are the cornerstone of modern quantum technology, enabling scalable computing through coherent control of macroscopic quantum states. Through a legac…
Unidirectional Dark-to-Bright Rescue in Cavity-Coupled Quantum Transport
Jack Diab, Arpit Arora, Taylor L. Patti +1
Strong light-matter coupling in optical microcavities can transport energy ballistically across an emitter array, but the same coupling buries most of the excitation in a manifold…
Inverse Design of Quantum Control Sequences with Fourier Neural Operators
Anastasia Pipi, Valentin Duruisseaux, Emily Been +4
Quantum optimal control is a key tool for steering quantum dynamics, but its computational cost grows rapidly with the Hilbert space dimension. Here, we introduce a Fourier Neural…
Quantum Simulation via Stochastic Combination of Unitaries
Joseph Peetz, Scott E. Smart, Prineha Narang
Quantum simulation algorithms often require numerous ancilla qubits and deep circuits, prohibitive for near-term hardware. We introduce a framework for simulating quantum channels…
Magneto-optic phonon resonances in magnetic topological EuCd2As2 via helical Raman spectroscopy
Jin Ho Kang, Liangbo Liang, Ioannis Petrides +6
EuCd2As2 materials have two magnetic ordering states: antiferromagnetic (AFM) and ferromagnetic (FM) when their chemical tunability is utilized. While AFM-EuCd2As2 has a nonzero ma…
An extensive theory of nonlinearly intercoupled pseudomodes for noise model reduction in circuit QED
M. Gabriela Boada G., Nicolas Dirnegger, Andrea Delgado +1
Superconducting circuit quantum electrodynamical (cQED) platforms present a persistent modeling challenge: the intrinsic nonlinearity of the Josephson potential couples to a dissip…
