Shape optimization of superconducting transmon qubits for low surface dielectric loss
Abstract Surface dielectric loss from superconducting transmon qubits is believed to be one of the dominant sources of decoherence. Reducing surface dielectric loss is crucial for achieving a high quality factor and a long relaxation time ( T 1 ), which can be engineered by carefully changing the geometry of …
