Entanglement, anti-flatness, and nonlocal nonstabilizerness: a unified perspective from entanglement spectrum
Lei-Yi-Nan Liu, Jian Cui
Entanglement and nonstabilizerness capture distinct aspects of quantum complexity, yet their relation through the entanglement spectrum remains only partially understood. Here we d…
Nonlocal nonstabilizerness for slightly entangled quantum many-body states
Lei-Yi-Nan Liu, Jian Cui
Nonlocal nonstabilizerness quantifies the irreducible magic resource encoded in bipartite entanglement, but its evaluation is generally hindered by a highly nonconvex optimization…
Preparation of Fractional Quantum Hall States on Quantum Computers
Hao Wu, Lei-Yi-Nan Liu, Zhao-Xin Pei +4
The realization of fractional quantum Hall (FQH) states, characterized by fractional charge and intrinsic topological order, on quantum computers represents a central challenge at…
Phase diagram of a dual-species Rydberg atom ladder
Lei-Yi-Nan Liu, Shi-Rong Peng, Ze-Yuan Huang +4
Dual-species Rydberg atom arrays extend single-species platforms by introducing competing interaction scales and enhanced quantum fluctuations, enabling phenomena beyond homogeneou…
Stabilizer Rényi Entropy for Translation-Invariant Matrix Product States
Lei-Yi-Nan Liu, Su Yi, Jian Cui
Magic, capturing the deviation of a quantum state from the stabilizer formalism, is a key resource underpinning the quantum advantage. The recently introduced stabilizer Rényi entr…
Distinct many-body scars and emergent quantum phases driven by competing interactions in two-species Rydberg arrays
Lei-Yi-Nan Liu, Shun-Yao Yu, Shi-Rong Peng +6
Rydberg atom arrays composed of multiple atomic species stand as a highly promising platform for quantum computation. However, the underlying physics of these systems as quantum ma…
