Observation of Interface Piezoelectricity in Superconducting Devices on Silicon
Haoxin Zhou, Eric Li, Kadircan Godeneli +7
The evolution of superconducting quantum processors is driven by the need to reduce errors and scale for fault-tolerant computation. Reducing physical qubit error rates requires fu…

Acceptor-induced bulk dielectric loss in superconducting circuits on silicon
Zi-Huai Zhang, Kadircan Godeneli, Justin He +4
The performance of superconducting quantum circuits is primarily limited by dielectric loss due to interactions with two-level systems (TLS). State-of-the-art circuits with enginee…

Non-Markovian dynamics of a superconducting qubit in a phononic bandgap
Mutasem Odeh, Kadircan Godeneli, Eric Li +5
The overhead to construct a logical qubit from physical qubits rapidly increases with the decoherence rate. Current superconducting qubits reduce dissipation due to two-level syste…
