Demonstration of a scalable all-solid-state refrigerator exploiting diffusion geometries and limiting interfacial conductances at temperatures below 1 kelvin
Robert M. Young, Zachary Stegen, John X. Przybysz +32
Solid-state refrigerators using Normal-metal/Insulator/Superconductor (NIS) junctions have previously demonstrated excellent electron cooling but limited ability to cool phonons. T…
Programmable CMOS DAC Operating in Cryogenic Environments for Controlling Superconducting Qubits
A. Pelteku, D. Reitz, M. Covington +15
This paper presents the design and test results of a CMOS current-based Digital to Analog Converter (DAC) that operates at cryogenic temperatures and that can be used to precisely…
Superconducting Flux Memory for Cryogenic Applications
Gregory R. Boyd, Jeremy Clark, Mark Covington +15
We report the development of flux memory for use with superconducting circuits. This technology stores persistent currents in superconducting loops on-chip to be used to provide fl…
Fast Microwave-free State Preparation and Measurement of Superconducting Qubits
R. Abraham, F. Amet, P. Anderson +212
Fast, high-fidelity, scalable state preparation and measurement is critical to the realization of a quantum computing system. The state-of-the-art methods for preparation and reado…
Transmon Phase Gates Controlled by Superconducting Soliton DAC
Derek Reitz, Tony X. Zhou, Aditya Sharma +10
We introduce a superconducting digital-to-analog converter (DAC) that filters control noise, provides native multiplexing, performs quantum gates in nanoseconds, and can be control…
Fullqubit alchemist: Quantum algorithm for alchemical free energy calculations
Po-Wei Huang, Gregory Boyd, Gian-Luca R. Anselmetti +11
Accurately computing the free energies of biological processes is a cornerstone of computer-aided drug design, but it is a daunting task. The need to sample vast conformational spa…
Low Depth Phase Oracle Using a Parallel Piecewise Circuit
Zhu Sun, Gregory Boyd, Zhenyu Cai +7
We explore the important task of applying a phase to a computational basis state . The closely related task of rotating a target qubit by an angle…
Low-Overhead Parallelisation of LCU via Commuting Operators
Gregory Boyd
The Linear Combination of Unitaries (LCU) method is a powerful scheme for the block encoding of operators but suffers from high overheads. In this work, we discuss the parallelisat…
Universal thermopower of bad metals
V. Zlatic, G. R. Boyd, J. K. Freericks
"Bad metals" have a large linear resistivity at high-T that is universally seen in oxides close to the Mott-Hubbard insulating phase. They also have an universal thermopower alpha(…
