The membership problem for constant-sized quantum correlations is undecidable

January 26, 2021
Author(s)
Carl A. Miller, Honghao Fu, William Slofstra
When two spatially separated parties make measurements on an unknown entangled quantum state, what correlations can they achieve? How difficult is it to determine whether a given correlation is a quantum correlation? These questions are central to problems

Cryogenic microwave loss in epitaxial Al/GaAs/Al trilayers for superconducting circuits

January 14, 2021
Author(s)
Corey Rae McRae, A. McFadden, Ruichen Zhao, Haozhi Wang, Junling Long, Tongyu Zhao, Sungoh Park, Mustafa Bal, Christopher J. Palmstrom, David P. Pappas
Epitaxially grown superconductor/dielectric/superconductor trilayers have the potential to form high-performance superconducting quantum devices and may even allow scalable superconducting quantum computing with low-surface-area qubits such as the merged

Developing Single Layer MOS Quantum Dots for Diagnostic Qubits

December 28, 2020
Author(s)
Yanxue Hong, Aruna Ramanayaka, Ryan Stein, Joshua M. Pomeroy
The design, fabrication and characterization of single metal gate layer, metal-oxide- semiconductor (MOS) quantum dot devices robust against dielectric breakdown are presented as prototypes for future diagnostic qubits. These devices were developed as a

Josephson Microwave Sources Applied to Quantum Information Systems

December 18, 2020
Author(s)
Adam J. Sirois, Manuel C. Castellanos Beltran, Anna E. Fox, Samuel P. Benz, Peter F. Hopkins
Quantum computers with thousands or millions of qubits will require a scalable solution for qubit control and readout electronics. Colocating these electronics at millikelvin temperatures has been proposed and demonstrated, but there exist significant
