Light Manipulation via Tunable Collective Quantum States in Waveguide-Coupled Bragg and Anti-Bragg Superatoms
Zhengqi Niu, Wei Nie, Daqiang Bao +8
A many-body quantum system which consists of collective quantum states, such as superradiant and subradiant states, behaves as a multi-level superatom in light-matter interaction.…
Thin film aluminum nitride surface acoustic wave resonators for quantum acoustodynamics
Wenbing Jiang, Junfeng Chen, Xiaoyu Liu +5
The quantum excitations of macroscopic surface acoustic waves (SAWs) have been tailored to control, communicate and transduce stationary and flying quantum states. However, the lim…
Quantum Bus of Metal Nanowire with Surface Plasmon Polaritons
Guo-Ping Guo, Zhi-Rong Lin, Tao Tu +4
We develop an architecture for distributed quantum computation using quantum bus of plasmonic circuits and spin qubits in self-assembled quantum dots. Deterministic quantum gates b…
Generation of quantum-dot cluster states with superconducting transmission line resonator
Zhi-Rong Lin, Guo-Ping Guo, Tao Tu +2
We propose an efficient method to generate cluster states in spatially separated double quantum dots with a superconducting transmission line resonator (TLR). When the detuning bet…
Quantum computation with graphene nanoribbon
Guo-Ping Guo, Zhi-Rong Lin, Xiao-Peng Li +2
We propose a scalable scheme to implement quantum computation in graphene nanoribbon. It is shown that electron or hole can be naturally localized in each zigzag region for a graph…
Coulomb blockade in graphene quantum dots
Qiong Ma, Tao Tu, Zhi-Rong Lin +2
We study the conductance spectrum of graphene quantum dots, both single and multiple cases. The single electron tunneling phenomenon is investigated and the periodicity, amplitude…
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…
Substrate Modulated Graphene Quantum Dot
Qiong Ma, Zhi-Rong Lin, Tao Tu +2
We propose a new method to use gapped graphene as barrier to confine electrons in gapless graphene and form a good quantum dot, which can be realized on an oxygen-terminated $SiO_{…
From weak to strong-coupling superconductivity tuned by substrate in TiN films
Yixin Liu, Yuchuan Liu, Zulei Xu +6
The interplay between substrates and superconducting thin films has attracted increasing attention. Here, we report an in-depth investigation on superconducting properties of the e…
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…
