Dissipative Channels Determine Open Electromagnetic Quantization
Hyunwoo Choi, Junwoo Gim, Thomas E. Roth +2
We formulate a quantization scheme for open electromagnetic systems with arbitrary passive boundary conditions. Rather than specifying reservoirs phenomenologically, the method ide…
Analytical Quantum Full-Wave Analysis of Few-Photon Transport Through a Superconducting Cavity Qubit
Soomin Moon, Thomas E. Roth
A promising way to scale up superconducting quantum computers is to link different devices together using propagating photons. Correspondingly, accurately modeling the quantum info…
Incorporating multi-qubit exchange coupling effects between transmon qubits in Maxwell-Schrödinger numerical methods
Ghazi Khan, Thomas E. Roth
Superconducting qubits have emerged as a leading platform for realizing quantum computers. Accurate modeling of these devices is essential for predicting performance, improving des…
Opportunities and Challenges of Computational Electromagnetics Methods for Superconducting Circuit Quantum Device Modeling: A Practical Review
Samuel T. Elkin, Ghazi Khan, Ebrahim Forati +5
High-fidelity numerical methods that model the physical layout of a device are essential for the design of many technologies. For methods that characterize electromagnetic effects,…
