Free Mode Removal and Mode Decoupling for Simulating General Superconducting Quantum Circuits

Understand

Superconducting quantum circuits is one of the leading candidates for a universal quantum computer.

• Designing novel qubit and multiqubit superconducting circuits requires the ability to simulate and analyze the properties of a general circuit.
• In particular, going outside the transmon approach, we cannot make assumptions on anharmonicity, thus precluding blackbox quantization approaches and necessitating the formal circuit quantization approach.
• We consider and solve two issues involved in simulating general superconducting circuits.
