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

Qubits

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

Amplifiers

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.
