Noise-Symmetry Optimization of Quantum Error-Corrected Metrology
Shuyun Su, Shengshi Pang
Quantum error correction (QEC) codes have emerged as a powerful tool to protect quantum-enhanced metrology against noise. However, the ability to correct errors alone does not guar…

Hamiltonian Conditions for Dark Modes in Multimode Bosonic Systems
Zuxin Wu, Shengshi Pang
Dark modes arise when destructive interference prevents selected bosonic degrees of freedom from coupling to environmental channels. We formulate a Hamiltonian criterion for identi…

Optimization for the propagation of a multiparticle quantum walk in a one-dimensional lattice
Daer Feng, Shengshi Pang
The quantum walk is a quantum counterpart of the classical random walk that exhibits nonclassical behaviors and outperforms the classical random walk in various aspects. It has bee…
