Collective Floquet engineering between two distant superconducting artificial atoms
Y. -H. Huang, Jiale Yuan, Z. Q. Niu +11
A one-dimensional waveguide is a crucial medium for transferring propagating quantum information between remote qubits, yet the photon-mediated interaction is typically fixed by th…
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…
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…
Tunable coherent microwave beam splitter and combiner at the single-photon level
Y. -H. Huang, K. -M. Hsieh, F. Aziz +10
A beam splitter is a key component used to direct and combine light paths in various optical and microwave systems. It plays a crucial role in devices like interferometers, such as…
Group delay controlled by the decoherence of a single artificial atom
Y. -T. Cheng, K. -M. Hsieh, B. -Y. Wu +12
The ability to slow down light at the single-photon level has applications in quantum information processing and other quantum technologies. We demonstrate two methods, both using…
Single-Atom Amplification Assisted by Multiple Sideband Interference in 1D Waveguide QED Systems
Kuan-Ting Lin, Ting Hsu, Fahad Aziz +4
This study conducts a theoretical investigation into the signal amplification arising from multiple Rabi sideband coherence within a one-dimensional waveguide quantum electrodynami…
Tuning atom-field interaction via phase shaping
Y. -T. Cheng, C. -H. Chien, K. -M. Hsieh +14
A coherent electromagnetic field can be described by its amplitude, frequency, and phase. All these properties can influence the interaction between the field and an atom. Here we…
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…
Coherent dynamics of a photon-dressed qubit
M. P. Liul, C. -H. Chien, C. -Y. Chen +6
We consider the dynamics and stationary regime of a capacitively-shunted transmon-type qubit in front of a mirror, affected by two signals: probe and dressing signals. By varying t…
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…
Ultimate quantum limit for amplification: a single atom in front of a mirror
Emely Wiegand, Ping-Yi Wen, Per Delsing +2
We investigate three types of amplification processes for light fields coupling to an atom near the end of a one-dimensional semi-infinite waveguide. We consider two setups where a…
Mirror, mirror: Landau-Zener-Stuckelberg-Majorana interferometry of a superconducting qubit in front of a mirror
P. Y. Wen, O. V. Ivakhnenko, M. A. Nakonechnyi +7
We investigate the Landau-Zener-Stuckelberg-Majorana interferometry of a superconducting qubit in a semi-infinite transmission line terminated by a mirror. The transmon-type qubit…
Large collective Lamb shift of two distant superconducting artificial atoms
P. Y. Wen, K. -T. Lin, A. F. Kockum +9
Virtual photons can mediate interaction between atoms, resulting in an energy shift known as a collective Lamb shift. Observing the collective Lamb shift is challenging, since it c…
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…
