Mitigation of Measurement-Induced State Transitions via a Fast-Load and Fast-Clear Readout
Wei-En Lin, Li-Chieh Hsiao, Chen-Hsun Ma +8
High-fidelity and rapid qubit readout is essential for superconducting quantum processors, typically realized through the quantum non-demolition (QND) dispersive interaction within…
Suppression of Quasiparticle Poisoning to Levels in Superconducting Qubits via Infrared Shielding
Wei-En Lin, Chen-Hsun Ma, Erh-Hsiang Yeh +7
Quasiparticle poisoning bottlenecks superconducting qubits, limiting coherence and the scalability of quantum processors. In this work, we systematically investigate quasiparticle…
Characterizing and Mitigating Flux Crosstalk in Superconducting Qubits-Couplers System
Myrron Albert Callera Aguila, Nien-Yu Li, Chen-Hsun Ma +12
Superconducting qubits have achieved exceptional gate fidelities, exceeding the error-correction threshold in recent years. One key ingredient of such improvement is the introducti…
Scaffold-Assisted Window Junctions for Superconducting Qubit Fabrication
Chung-Ting Ke, Jun-Yi Tsai, Yen-Chun Chen +13
The superconducting qubit is one of the promising directions in realizing fault-tolerant quantum computing (FTQC), which requires many high-quality qubits. To achieve this, it is d…
