Benchmarking exchange-only control of a 48-spin singlet manifold
HRL Quantum Team, Microsoft Collaborators, : +125
Exchange-only quantum computing benefits from high fidelity and straightforward control afforded by the exchange interaction. However, independently controllable qubits must be enc…
A digitally controlled silicon quantum processing unit
Members of the HRL Quantum Team, Collaborators, : +255
Commercially-relevant quantum computers will require large numbers of high-performing qubits that can be manufactured, integrated, and controlled at scale. Silicon exchange-only (E…
Emergence of Ferromagnetism Through the Metal-Insulator Transition in Undoped Indium Tin Oxide Films
Samuel Mumford, Tiffany Paul, Aharon Kapitulnik
We present a detailed study of the emergence of bulk ferromagnetism in low carrier density samples of undoped indium tin oxide (ITO). We used annealing to increase the density of o…
Source mass characterization in the ARIADNE axion experiment
Chloe Lohmeyer, Nancy Aggarwal, Asimina Arvanitaki +22
The Axion Resonant InterAction Detection Experiment (ARIADNE) is a collaborative effort to search for the QCD axion using nuclear magnetic resonance (NMR), where the axion acts as…
Sample Shape and Boundary Dependence of Measured Transverse Thermal Properties
Samuel Mumford, Tiffany Paul, Erik Kountz +1
Despite increased interest in thermal Hall measurements for the analysis of insulating quantum materials, there remains large uncertainty in such measurements due to contact misali…
A Cantilever Torque Magnetometry Method for the Measurement of Hall Conductivity of Highly Resistive Samples
Samuel Mumford, Tiffany Paul, Seung Hwan Lee +2
We present the first measurements of Hall conductivity utilizing a new torque magnetometry method designed for insulators. A Corbino disk exhibits a magnetic dipole moment proporti…
Progress on the ARIADNE axion experiment
A. A. Geraci, H. Fosbinder-Elkins, C. Lohmeyer +17
The Axion Resonant InterAction Detection Experiment (ARIADNE) is a collaborative effort to search for the QCD axion using techniques based on nuclear magnetic resonance. In the exp…
Entanglement structure of non-equilibrium steady states
Raghu Mahajan, C. Daniel Freeman, Sam Mumford +2
We study the problem of calculating transport properties of interacting quantum systems, specifically electrical and thermal conductivities, by computing the non-equilibrium steady…
