A High Performance Compiler for Very Large Scale Surface Code Computations

George Watkins, Hoang Minh Nguyen, Keelan Watkins +3

We present the first high performance compiler for very large scale quantum error correction: it translates an arbitrary quantum circuit to surface code operations based on lattice…

Characterization and optimized engineering of bosonic quantum interfaces under single-mode operational constraints

Pak-Tik Fong, Sheung Chi Poon, Hoi-Kwan Lau

Controlling the quantum interface between two bosonic modes is essential in countless implementations of quantum information processing. However, full controllability is rarely ach…

Efficient in-situ generation of photon-memory entanglement in a nonlinear cavity

Hoi-Kwan Lau, Hong Qiao, Aashish A. Clerk +1

Parametrically driving an optical cavity that simultaneously couples to an atomic ensemble quantum memory enables in-situ generation of multimode photon-memory entanglement. A high…

Asymmetry-Based Quantum Backaction Suppression in Quadratic Optomechanics

Vincent Dumont, Hoi-Kwan Lau, Aashish A. Clerk +1

As the field of optomechanics advances, quadratic dispersive coupling (QDC) promise an increasingly feasible class of qualitatively new functionality. However, the leading QDC geom…

Dissipative superradiant spin amplifier for enhanced quantum sensing

Martin Koppenhöfer, Peter Groszkowski, Hoi-Kwan Lau +1

Quantum metrology protocols exploiting ensembles of two-level systems and Ramsey-style measurements are ubiquitous. However, in many cases excess readout noise severely degrade…

Reservoir-engineered spin squeezing: macroscopic even-odd effects and hybrid-systems implementations

Peter Groszkowski, Martin Koppenhöfer, Hoi-Kwan Lau +1

We revisit the dissipative approach to producing and stabilizing spin-squeezed states of an ensemble of two-level systems, providing a detailed analysis of two surprising yet g…
