Giant intrinsic nonlinear phonon-magnon coupling in the antiferromagnet CoF
M. A. Prosnikov, M. Bal, R. V. Pisarev +2
The observation of strongly coupled lattice and spin dynamics in altermagnet CoF is reported. On the background of the expected spin-phonon interaction leading to renormalizati…
Systematic Improvements in Transmon Qubit Coherence Enabled by Niobium Surface Encapsulation
Mustafa Bal, Akshay A. Murthy, Shaojiang Zhu +37
We present a novel transmon qubit fabrication technique that yields systematic improvements in T relaxation times. We fabricate devices using an encapsulation strategy that inv…
Implementing two-qubit gates at the quantum speed limit
Joel Howard, Alexander Lidiak, Casey Jameson +8
The speed of elementary quantum gates, particularly two-qubit gates, ultimately sets the limit on the speed at which quantum circuits can operate. In this work, we experimentally d…
A universal quantum gate set for transmon qubits with strong ZZ interactions
Junling Long, Tongyu Zhao, Mustafa Bal +13
High-fidelity single- and two-qubit gates are essential building blocks for a fault-tolerant quantum computer. While there has been much progress in suppressing single-qubit gate e…
Cryogenic microwave loss in epitaxial Al/GaAs/Al trilayers for superconducting circuits
C. R. H. McRae, A. McFadden, R. Zhao +7
Epitaxially-grown superconductor/dielectric/superconductor trilayers have the potential to form high-performance superconducting quantum devices and may even allow scalable superco…
Merged-element transmon
R. Zhao, S. Park, T. Zhao +4
Transmon qubits are ubiquitous in the pursuit of quantum computing using superconducting circuits. However, they have some drawbacks that still need to be addressed. Most important…
