Circuit Modeling of Q-Bits and Superconducting Microwave Resonators

Equivalent circuits of a two-state quantum system

Superconducting quantum devices are emerging as possible realization for quantum computers.

We are designing microwave circuits to manipulate and read-out quantum bits.

We combine well-established engineering software packages for a finite-element solution of the electromagnetic field problem and develop "circuit models" to understand more about the coupling of electromagnetic fields and quantum systems.
