-PSD: Scalable Approximate SNR-Optimised Polynomial Stein Discrepancies
Minh-Long Nguyen, Thanh-Long Vu, Christopher Drovandi +2
Polynomial Stein discrepancies (PSD) provide a scalable alternative to kernel Stein methods for measuring sample quality and goodness-of-fit testing, but their statistical properti…
Color it, Code it, Cancel it: k-local dynamical decoupling from classical additive codes
Minh T. P. Nguyen, Maximilian Rimbach-Russ, Stefano Bosco
Dynamical decoupling is a central technique in quantum computing for actively suppressing decoherence and systematic imperfections through sequences of single-qubit operations. Con…
Fault-Tolerant Non-Clifford GKP Gates using Polynomial Phase Gates and On-Demand Noise Biasing
Minh T. P. Nguyen, Mackenzie H. Shaw
The Gottesman-Kitaev-Preskill (GKP) error correcting code uses a bosonic mode to encode a logical qubit, and has the attractive property that its logical Clifford gates can be impl…
Many-body interferometry with semiconductor spins
Daniel Jirovec, Stefano Reale, Pablo Cova-Fariña +9
Quantum simulators enable studies of many-body phenomena which are intractable with classical hardware. Spins in devices based on semiconductor quantum dots promise precise electri…
Single-step high-fidelity three-qubit gates by anisotropic chiral interactions
Minh T. P. Nguyen, Maximilian Rimbach-Russ, Lieven M. K. Vandersypen +1
Direct multi-qubit gates are becoming critical to facilitate quantum computations in near-term devices by reducing the gate counts and circuit depth. Here, we demonstrate that fast…
Chip Placement with Diffusion Models
Vint Lee, Minh Nguyen, Leena Elzeiny +3
Macro placement is a vital step in digital circuit design that defines the physical location of large collections of components, known as macros, on a 2D chip. Because key performa…
