Quantum Processing Group

The Quantum Processing Group develops new technologies for processing information using superconducting circuits. In addition, advanced fabrication techniques are being developed to enable true scaling of both superconducting quantum computers and ion-trap based systems.

Projects and Programs


The Qubits Project develops new geometries for superconducting quantum binary devices as fundamental building blocks for quantum computing.


To process quantum information it is important to have amplifiers with wide bandwidth, high dynamic range, and low noise.

Ion Traps

The Ion Traps Project collaborates with PML's Ion Storage Group to lower the intrinsic heating of ions from ion trap components.


Enhanced superconducting transition temperature in electroplated rhenium

David P. Pappas, Don David, Mustafa Bal, Ilke Arslan, Paul T. Blanchard, Ronald B. Goldfarb, Dustin A. Hite, Hsiang S. Ku, Russell E. Lake, Junling Long, Alexana Roshko, Lee D. Pappas, Britton L. Plourde, Jianguo Wen, Xian Wu, Corey Rae H. McRae
We show that electroplated Re films in multilayers with noble metals such as Cu, Au, and Pd have an enhanced superconducting critical temperature relative to

High coherence plane breaking packaging for superconducting qubits

David P. Pappas, Xian Wu, Nicholas T. Bronn, Salvatore B. Olivadese, Vivekananda P. Adiga, Jerry M. Chow
Wedemonstrate a pogo pin package for a superconducting quantum processor specifically designed with a nontrivial layout topology (e.g., a center qubit that
