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…
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…
Hybrid Oscillator-Qubit Quantum Processors: Instruction Set Architectures, Abstract Machine Models, and Applications
Yuan Liu, Shraddha Singh, Kevin C. Smith +11
Quantum computing with discrete variable (DV, qubit) hardware is approaching the large scales necessary for computations beyond the reach of classical computers. However, important…
Strategies and trade-offs for controllability and memory time of ultra-high-quality microwave cavities in circuit QED
Iivari Pietikäinen, Ondřej Černotík, Alec Eickbusch +4
Three-dimensional microwave cavity resonators have been shown to reach lifetimes of the order of a second by maximizing the cavity volume relative to its surface, using better mate…
