Localized Thermometry via Dayem Bridges Integrated on Superconducting Qubit Chips
Ella O. Lachman, Dave P. Pappas, Jayss Marshall +1
Accurate knowledge of the on-chip temperature is essential for understanding and optimizing the performance of superconducting qubits, yet direct thermometry at millikelvin tempera…
Identifying Materials-Level Sources of Performance Variation in Superconducting Transmon Qubits
Akshay A. Murthy, Mustafa Bal, Michael J. Bedzyk +46
The Superconducting Materials and Systems (SQMS) Center, a DOE National Quantum Information Science Research Center, has conducted a comprehensive and coordinated study using super…
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…
Demonstration of Universal Parametric Entangling Gates on a Multi-Qubit Lattice
M. Reagor, C. B. Osborn, N. Tezak +56
We show that parametric coupling techniques can be used to generate selective entangling interactions for multi-qubit processors. By inducing coherent population exchange between a…
Parametrically Activated Entangling Gates Using Transmon Qubits
S. Caldwell, N. Didier, C. A. Ryan +59
We describe and implement a family of entangling gates activated by radio-frequency flux modulation applied to a tunable transmon that is statically coupled to a neighboring transm…
