Error-Tolerant Geometric Quantum Control for Logical Qubits with Minimal Resource
Tao Chen, Zheng-Yuan Xue, Z. D. Wang
Geometric quantum computation offers a practical strategy toward robust quantum computation due to its inherently error tolerance. However, the rigorous geometric conditions lead t…
Quantum Gaussian filter for exploring ground-state properties
Min-Quan He, Dan-Bo Zhang, Z. D. Wang
Filter methods realize a projection from a superposed quantum state onto a target state, which can be efficient if two states have sufficient overlap. Here we propose a quantum Gau…
Quantum kernels with squeezed-state encoding for machine learning
Long Hin Li, Dan-Bo Zhang, Z. D. Wang
Kernel methods are powerful for machine learning, as they can represent data in feature spaces that similarities between samples may be faithfully captured. Recently, it is realize…
Quantum emulation of topological magneto-optical effects using ultracold atoms
Zhen Zheng, Z. D. Wang
Magneto-optical effect is a fundamental but broad concept in magnetic mediums. Here we propose a scheme for its quantum emulation using ultracold atoms. By representing the light-m…
Non-Hermitian spatial symmetries and their stabilized normal and exceptional topological semimetals
W. B. Rui, Zhen Zheng, Chenjie Wang +1
We study non-Hermitian spatial symmetries -- a class of symmetries that have no counterparts in Hermitian systems -- and study how normal and exceptional semimetals can be stabiliz…
Intertwined Weyl phases emergent from higher-order topology and unconventional Weyl fermions via crystalline symmetry
W. B. Rui, Zhen Zheng, Moritz M. Hirschmann +3
We discover three-dimensional intertwined Weyl phases, by developing a theory to create topological phases. The theory is based on intertwining existing topological gapped and gapl…
