A Deterministic Dimension Property of Twisted Goppa Codes
Kai Wang
This paper presents a large-scale computational study on the dimensional properties of twisted Goppa codes. Through the systematic analysis of over 50,000 parameter sets, we uncove…
Quantum Purification for Amplitude Damping Noise
Kai Wang, Zhen-Yang Peng
Noise poses a fundamental challenge to quantum information processing, with amplitude-damping (AD) noise being particularly detrimental. Preserving high-fidelity quantum systems th…
Unifying Anderson transitions and topological amplification in non-Hermitian chains
Clément Fortin, Kai Wang, T. Pereg-Barnea
Non-Hermitian systems with non-reciprocal hopping may display the non-Hermitian skin effect, where states under open boundary conditions localize exponentially at one edge of the s…
Topological Amplification of the Bosonic Kitaev Chain with Non-Uniform Loss
Clément Fortin, Kai Wang, T. Pereg-Barnea
The bosonic Kitaev chain is known to have extraordinary properties distinct from its fermionic counterpart. For example, it exhibits the non-Hermitian skin effect -- its eigenmodes…
