Mixed-State Phase Transitions in Measurement-Dressed Imaginary-Time Evolution
Yi-Ming Ding, Zenan Liu, Xu Tian +3
Motivated by the ubiquity of decoherence in quantum hardware and the growing role of imaginary-time evolution (ITE) in quantum algorithms, we investigate how many-body correlations…
Exploring the limit of the Lattice-Bisognano-Wichmann form describing the Entanglement Hamiltonian: A quantum Monte Carlo study
Siyi Yang, Yi-Ming Ding, Zheng Yan
As a powerful theoretical construct, the entanglement Hamiltonian (EH) encapsulates the essential entanglement properties of a quantum many-body system. From the EH, one can extrac…
Boundary Renormalization Group Flow of Entanglement Entropy at a (2+1)-Dimensional Quantum Critical Point
Zhiyan Wang, Zhe Wang, Yi-Ming Ding +3
We investigate the second-order Rényi entanglement entropy at the quantum critical point of a spin-1/2 antiferromagnetic Heisenberg model on a columnar dimerized square lattice. Th…
Robustness of Magic in the quantum Ising chain via Quantum Monte Carlo tomography
Hari Timsina, Yi-Ming Ding, Emanuele Tirrito +5
We study the behavior of magic as a bipartite correlation in the quantum Ising chain across its quantum phase transition, and at finite temperature. In order to quantify the magic…
Complete finite-size scaling theory of Renyi thermal entropy for second, first and weak first order quantum phase transitions
Zhe Wang, Yanzhang Zhu, Yi-Ming Ding +2
Establishing the nature of a quantum phase transition in finite-size simulations -- whether continuous, first-order, or weak first-order -- is a fundamental challenge in quantum ma…
Bell sampling in Quantum Monte Carlo simulations
Poetri Sonya Tarabunga, Yi-Ming Ding
Quantum Monte Carlo (QMC) methods are essential for the numerical study of large-scale quantum many-body systems, yet their utility has been significantly hampered by the difficult…
Evaluating many-body stabilizer Rényi entropy by sampling reduced Pauli strings: singularities, volume law, and nonlocal magic
Yi-Ming Ding, Zhe Wang, Zheng Yan
We present a novel quantum Monte Carlo method for evaluating the -stabilizer Rényi entropy (SRE) for any integer . By interpreting -SRE as partition function ratios,…
