Practical Error Suppression and Mitigation for Reliable Quantum Computing
Han-Ze Li, Mengjie Yang, Xianquan Yan +3
Quantum computing is entering a transitional regime between noisy intermediate-scale quantum (NISQ) processing and early fault-tolerant quantum computation (FTQC), in which increas…
Exceptional activated mode theory for generalized real-complex transitions
Mengjie Yang, Alexander N. Poddubny, Ching Hua Lee
Real-to-complex spectral transitions mark the onset of amplification in non-Hermitian systems, but their thresholds are often treated as model-specific quantities. Here we develop…
Nonlocality-induced critical-length hierarchy from non-Hermitian competition
Mengjie Yang, Alexander N. Poddubny, Ching Hua Lee
Spectral transitions in non-Hermitian lattices often arise from the competition between non-reciprocal skin accumulation and inter-component hybridization. In short-range systems f…
Layer-Resolved Topological Metals in the Bilayer Lieb Lattice
Mengjie Yang, S Rahul, Giandomenico Palumbo
We identify a two-dimensional time-reversal-invariant topological metallic phase on a bilayer Lieb lattice, characterized by a quantized layer--resolved pseudo-spin Chern number. W…
