Dark state as a measurable state by a dispersive readout without a Purcell limit
Wei-Chen Chien, Jyh-Yang Wang, Yen-Yu Chiang +6
It is believed that the enhancement in qubit-resonator coupling allows a better dispersive readout but introduces greater Purcell loss. In this work, we propose that a dark mode in…
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…
Cavity quantum electrodynamics with dressed states of a superconducting artificial atom
Yu-Han Chang, Dmytro Dubyna, Wei-Chen Chien +3
We experimentally studied the microwave response of a transmon artificial atom coupled to two closely spaced resonant modes. When the atom is under driven with one of the modes, th…
