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…
Fast and length-independent transport time supported by topological edge states in finite-size Su-Schrieffer-Heeger chains
Yu-Han Chang, Nadia Daniela Rivera Torres, Santiago Figueroa Manrique +9
In order to transport information with topological protection, we explore experimentally the fast transport time using edge states in one-dimensional Su-Schrieffer-Heeger (SSH) cha…
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…
Probing topological protected transport in finite-sized Su-Schrieffer-Heeger chains
Yu-Han Chang, Nadia Daniela Rivera Torres, Santiago Figueroa Manrique +9
In order to transport information with topological protection, we reveal and demonstrate experimentally the existence of a characteristic length , coined as the transport leng…
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…
Experimental determination of the elastic cotunneling rate in a hybrid single-electron box
Chia-Heng Sun, Po-Chen Tai, Jheng-An Jiang +3
We report measurements of charge configurations and charge transfer dynamics in a hybrid single-electron box composed of aluminum and copper. We used two single-electron transistor…
Evidence for Suppression of Superconductivity by Spin Imbalance in Co-Al-Co single electron transistors
C. D. Chen, Watson Kuo, D. S. Chung +2
Spin imbalance is predicted to lead to suppression of superconductivity. We report phenomena manifesting this effect under spin-polarized quasiparticle currents in ferromagnet-supe…
