Resonance fluorescence of an artificial atom with a time-delayed coherent feedback
Ching-Yeh Chen, Gavin Crowder, Zheng-Qi Niu +7
The model of light-matter interaction in quantum electrodynamics typically relies on the Markovian approximation, which assumes that the system's future evolution depends solely on…
Coherent transfer via parametric control of normal-mode splitting in a superconducting multimode resonator
Kai-I Chu, Xiao-Cheng Lu, Hsin Chang +5
Microwave storage and retrieval are essential capabilities for superconducting quantum circuits. Here, we demonstrate an on-chip multimode resonator in which strong parametric modu…
Tunable frequency conversion and comb generation with a superconducting artificial atom
Fahad Aziz, Zhengqi Niu, Tzu-Yen Hsieh +12
We investigate the power spectral density emitted by a superconducting artificial atom coupled to the end of a semi-infinite transmission line and driven by two continuous radio-fr…
Microwave amplification via interfering multi-photon processes in a half-waveguide quantum electrodynamics system
Fahad Aziz, Kuan Ting Lin, Ping Yi Wen +15
We investigate the amplification of a microwave probe signal by a superconducting artificial atom, a transmon, strongly coupled to the end of a one-dimensional semi-infinite transm…
Deterministic loading and phase shaping of microwaves onto a single artificial atom
W. -J. Lin, Y. Lu, P. Y. Wen +12
Loading quantum information deterministically onto a quantum node is an important step towards a quantum network. Here, we demonstrate that coherent-state microwave photons, with a…
Reflective amplification without population inversion from a strongly driven superconducting qubit
P. Y. Wen, A. F. Kockum, H. Ian +3
Amplification of optical or microwave fields is often achieved by strongly driving a medium to induce population inversion such that a weak probe can be amplified through stimulate…
Observation of Collective Coulomb Blockade in a Gate-controlled Linear Quantum-dot Array
Wen-Yao Wei, Tung-Sheng Lo, Chiu-Chun Tang +8
The quantum transport of electrons in an artificial atom, such as a quantum dot (QD), is governed by the Coulomb blockade (CB) effects, revealing the ground-state charge configurat…
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…
Pulsed THz radiation due to phonon-polariton effect in [110] ZnTe crystal
Chien-Ming Tu, Shin-An Ku, Wei-Chen Chu +3
Pulsed terahertz (THz) radiation, generated through optical rectification (OR) by exciting [110] ZnTe crystal with ultrafast optical pulses, typically consists of only a few cycles…
Probing onset of strong localization and electron-electron interactions with the presence of direct insulator-quantum Hall transition
Shun-Tsung Lo, Kuang Yao Chen, T. L. Lin +11
We have performed low-temperature transport measurements on a disordered two-dimensional electron system (2DES). Features of the strong localization leading to the quantum Hall eff…
Transition between Quantum States in a Parallel-Coupled Double-Quantum-Dot
J. C. Chen, A. M. Chang, M. R. Melloch
Strong electron and spin correlations in a double-quantum-dot (DQD) can give rise to different quantum states. We observe a continuous transition from a Kondo state exhibiting a si…
