Interface Piezoelectric Loss in Superconducting Qubits
Haoxin Zhou, Kangdi Yu, Yashwanth Balaji +5
Dissipation remains a central obstacle to improving superconducting quantum circuits, yet the microscopic origins of loss in widely used materials platforms are not fully understoo…
Entanglement of a nuclear spin qubit register in silicon photonics
Hanbin Song, Xueyue Zhang, Lukasz Komza +9
Color centers provide an optical interface to quantum registers based on electron and nuclear spin qubits in solids. The T center in silicon is an emerging spin-photon interface th…
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…
A Nanomechanical Atomic Force Qubit
Shahin Jahanbani, Zi-Huai Zhang, Binhan Hua +5
Silicon nanomechanical resonators display ultra-long lifetimes at cryogenic temperatures and microwave frequencies. Achieving quantum control of single-phonons in these devices has…
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…
