Thermally-Polarized Solid-State Spin Sensor

Reginald Wilcox, Erik Eisenach, John Barry +4

Quantum sensors based on spin defect ensembles have seen rapid development in recent years, with a wide array of target applications. Historically, these sensors have used optical…

Error mitigation via stabilizer measurement emulation

A. Greene, M. Kjaergaard, M. E. Schwartz +16

Dynamical decoupling (DD) is a widely-used quantum control technique that takes advantage of temporal symmetries in order to partially suppress quantum errors without the need reso…

Cavity quantum electrodynamic readout of a solid-state spin sensor

Erik R. Eisenach, John F. Barry, Michael F. O'Keeffe +4

Robust, high-fidelity readout is central to quantum device performance. Overcoming poor readout is an increasingly urgent challenge for devices based on solid-state spin defects, p…

Programming a quantum computer with quantum instructions

Morten Kjaergaard, Mollie E. Schwartz, Ami Greene +20

The equivalence between the instructions used to define programs and the input data on which the instructions operate is a basic principle of classical computer architectures and p…

Hamiltonian Engineering with Constrained Optimization for Quantum Sensing and Control

Michael F. O'Keeffe, Lior Horesh, John F. Barry +2

While quantum devices rely on interactions between constituent subsystems and with their environment to operate, native interactions alone often fail to deliver targeted performanc…

Renormalization of the tunnel splitting in a rotating nanomagnet

Michael F. O'Keeffe, Eugene M. Chudnovsky

We study spin tunneling in a magnetic nanoparticle with biaxial anisotropy that is free to rotate about its anisotropy axis. Exact instanton of the coupled equations of motion is f…
