Non-Abelian Quantum Signal Processing: A Composite Pulse for Fast Analytic Control of Hybrid Oscillator-Qubit Processors
Shraddha Singh, Baptiste Royer, Steven M. Girvin
Quantum Signal Processing (QSP) transforms a unitary parameterized by a classical variable into one governed by a polynomial function . Though quantum mechanics is linear…
Constrained many-body phases in a -Higgs lattice gauge theory
Alexander Schuckert, Stefan Kühn, Kevin C. Smith +2
We study the ground-state phase diagram of a one-dimensional lattice gauge theory coupled to soft-core bosonic matter at unit filling, inspired by the Higgs sector o…
Exact amplitudes of parametric processes in driven Josephson circuits
Roman Baskov, Daniel K. Weiss, Steven M. Girvin
We present a general approach for analyzing arbitrary parametric processes in Josephson circuits within a single degree of freedom approximation. Introducing a systematic normal-or…
Quantum Error Correction of Qudits Beyond Break-even
Benjamin L. Brock, Shraddha Singh, Alec Eickbusch +5
Hilbert space dimension is a key resource for quantum information processing. A large Hilbert space is not only an essential requirement for quantum error correction, but it can al…
Hybrid Oscillator-Qubit Quantum Processors: Simulating Fermions, Bosons, and Gauge Fields
Eleanor Crane, Kevin C. Smith, Teague Tomesh +9
We develop a hybrid oscillator-qubit processor framework for quantum simulation of strongly correlated fermions and bosons that avoids the boson-to-qubit mapping overhead encounter…
Toward Mixed Analog-Digital Quantum Signal Processing: Quantum AD/DA Conversion and the Fourier Transform
Yuan Liu, John M. Martyn, Jasmine Sinanan-Singh +3
Signal processing stands as a pillar of classical computation and modern information technology, applicable to both analog and digital signals. Recently, advancements in quantum in…
