Collective quantum phase slips in multiple nanowire junctions
Zeng-Zhao Li, Tie-Fu Li, Chi-Hang Lam +1
Realization of robust coherent quantum phase slips represents a significant experimental challenge. Here we propose a new design consisting of multiple nanowire junctions to realiz…
Cooling a nanomechanical resonator by a triple quantum dot
Zeng-Zhao Li, Shi-Hua Ouyang, Chi-Hang Lam +1
We propose an approach for achieving ground-state cooling of a nanomechanical resonator (NAMR) capacitively coupled to a triple quantum dot (TQD). This TQD is an electronic analog…
Probing the quantum behaviors of a nanomechanical resonator coupled to a double quantum dot
Zeng-Zhao Li, Shi-Hua Ouyang, Chi-Hang Lam +1
We propose a current correlation spectrum approach to probe the quantum behaviors of a nanome-chanical resonator (NAMR). The NAMR is coupled to a double quantum dot (DQD), which ac…
Protection of center-spin coherence by a dynamically polarized nuclear spin core
Wenxian Zhang, Jian-Liang Hu, Jun Zhuang +2
Understanding fully the dynamics of coupled electron-nuclear spin systems, which are important for the development of long-lived qubits based on solid-state systems, remains a chal…
Cooling a mechanical resonator by quantum interference in a triple quantum dot
Shi-Hua Ouyang, Chi-Hang Lam, J. Q. You
We propose an approach to cool a mechanical resonator (MR) via quantum interference in a triple quantum dot (TQD) capacitively coupled to the MR. The TQD connected to three electro…
Topological states and braiding statistics using quantum circuits
J. Q. You, Xiao-Feng Shi, Franco Nori
Using superconducting quantum circuits, we propose an approach to construct a Kitaev lattice, i.e., an anisotropic spin model on a honeycomb lattice with three types of nearest-nei…
Resonant peak splitting for ballistic conductance in magnetic superlattices
Z. Y. Zeng, L. D. Zhang, X. H. Yan +1
We investigate theoretically the resonant splitting of ballistic conductance peaks in magnetic superlattices. It is found that, for magnetic superlattices with periodically arrange…
