Catastrophes, Optical Multistabilities, and Chiral Photocurrent Hysteresis in Driven Weyl Semimetals
Christopher Yang, Gil Refael, Frederik Nathan
The unique band topology of Weyl semimetals provides them with a diverse array of strong photovoltaic response phenomena. Here we explore how plasma screening affects these phenome…
Bang-bang protocol for nondispersive qubit readout
Nina del Ser, Yinan Chen, Jacob Steiner +1
Fast, precise, and quantum-non-demolition (QND) readout of superconducting qubits is a fundamental component of high-fidelity quantum sensing and computation. Conventional approach…
Self-organized Floquet band geometry in cavity-driven quantum materials
Christopher Yang, Gil Refael, Mark S. Rudner +1
Floquet engineering has emerged as a powerful route to dynamically control band structure and topology in quantum materials, but most implementations rely on externally imposed las…
Parametric Instabilities of Correlated Quantum Matter
Gal Shavit, Gil Refael
Collective bosonic excitations are a fascinating aspect of broken-symmetry correlated phases. A wealth of such phases emerged in tailored moiré heterostructures, where, in addition…
Exponentially robust non-Clifford gate in a driven-dissipative circuit
Liam O'Brien, Gil Refael, Frederik Nathan
Recent work (Nathan et al, arXiv:2405.05671) proposed an architecture for a dissipatively stabilized GKP qubit, and protocols for protected Clifford gates. Here we propose a protoc…
Impact of Josephson junction array modes on fluxonium readout
Shraddha Singh, Gil Refael, Aashish Clerk +1
Dispersive readout of superconducting qubits is often limited by readout-drive-induced transitions between qubit levels. While there is a growing understanding of such effects in t…

Ruairidh Sutcliffe, Kathleen Hart, Gil Refael +1
The dynamics of magnetic moments coupled to phonons is of great interest for understanding spin transport in solids as well as for our ability to control magnetism via tailored pho…
Evidence of Floquet electronic steady states in graphene under continuous-wave mid-infrared irradiation
Yijing Liu, Christopher Yang, Gabriel Gaertner +9
Light-induced phenomena in materials can exhibit exotic behavior that extends beyond equilibrium properties, offering new avenues for understanding and controlling electronic phase…
Bosonic Entanglement and Quantum Sensing from Energy Transfer in two-tone Floquet Systems
Yinan Chen, Andreas Elben, Angel Rubio +1
Quantum-enhanced sensors, which surpass the standard quantum limit (SQL) and approach the fundamental precision limits dictated by quantum mechanics, are finding applications acros…
Hardware-efficient quantum error correction via concatenated bosonic qubits
Harald Putterman, Kyungjoo Noh, Connor T. Hann +118
In order to solve problems of practical importance, quantum computers will likely need to incorporate quantum error correction, where a logical qubit is redundantly encoded in many…
Ephemeral Superconductivity Atop the False Vacuum
Gal Shavit, Stevan Nadj-Perge, Gil Refael
A many body system in the vicinity of a first-order phase transition may get trapped in a local minimum of the free energy landscape. These so-called false-vacuum states may surviv…
Self-correcting GKP qubit and gates in a driven-dissipative circuit
Frederik Nathan, Liam O'Brien, Kyungjoo Noh +4
We show that a self-correcting GKP qubit can be realized with a high-impedance LC circuit coupled to a resistor and a Josephson junction via a controllable switch. When activating…
Quantized Acoustoelectric Floquet Effect in Quantum Nanowires
Christopher Yang, Will Hunt, Gil Refael +1
External coherent fields can drive quantum materials into non-equilibrium states, revealing exotic properties that are unattainable under equilibrium conditions -- an approach know…
Phonon-driven multipolar dynamics in a spin-orbit coupled Mott insulator
Kathleen Hart, Ruairidh Sutcliffe, Gil Refael +1
Motivated by advances in pump-probe experiments and light-driven phenomena, we theoretically study the impact of pumped and driven phonons in Mott insulators which host multipole m…
