Protection of quantum evolutions under parity-time symmetric non-Hermitian Hamiltonians by dynamical decoupling
Ji Bian, Kunxu Wang, Pengfei Lu +7
Parity-time (PT) symmetric non-Hermitian Hamiltonians bring about many novel features and interesting applications such as quantum gates faster than those in Hermitian systems, and…
A single-atom level mechano-optical transducer for ultrasensitive force sensing
Yang Liu, Pengfei Lu, Xinxin Rao +6
Using light as a probe to detect a mechanical motion is one of the most successful experimental approaches in physics. The history of mechanical sensing based on the reflection, re…
Frequency stabilization of a 739 nm laser to an spectrum for trapped Ytterbium ions
Hao Wu, PengFei Lu, Yang Liu +6
We report on the frequency stabilization of a 739 nm Ti:sapphire laser to a hyperfine component of the B(1)-X(11) P(70) transition using acousto-optic modulation tran…
Shannon Entropy and Diffusion Coeffcient in Parity-Time Symmetric Quantum Walks
Zhiyu Tian, Yang Liu, Le Luo
Non-Hermitian topological edge states have many intriguing properties, but have so far mainly been discussed in terms of bulk-boundary correspondence. Here we propose to use a bulk…
