Quantum Monte Carlo in the Age of Many-Body Quantum Information
Yi-Ming Ding, Bin-Bin Mao, Zheng Yan
Quantum Monte Carlo (QMC) methods are among the central numerical tools for studying strongly correlated quantum many-body systems, particularly in higher dimensions. As quantum in…
Strong-to-Weak Spontaneous Symmetry Breaking in a D Transverse-Field Ising Model under Decoherence
Yi-Ming Ding, Yuxuan Guo, Zhen Bi +1
Decoherence in many-body quantum systems can give rise to intrinsically mixed-state phases and phase transitions beyond the pure-state paradigm. Here we study the D transver…
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…
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…
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,…
Tracking the variation of entanglement Rényi negativity: a quantum Monte Carlo study
Yi-Ming Ding, Yin Tang, Zhe Wang +3
Entanglement entropy has been a powerful tool for analyzing phases and criticality in pure ground states via quantum Monte Carlo (QMC). However, mixed-state entanglement, relevant…
Universal Behavior in Entanglement Entropy Reveals Quantum Criticality and Underlying Symmetry Breaking
Zhe Wang, Zehui Deng, Zenan Liu +5
Entanglement plays a key role in quantum physics, but how much information it can extract from many-body systems is still an open question, particularly regarding quantum criticali…
Surface phase transitions in a (1+1)-dimensional conformal field theory boundary coupled to a (2+1)-dimensional bulk
Zhe Wang, Shang-Qiang Ning, Zenan Liu +4
We design a (2+1))-dimensional [(2+1)D] quantum spin model in which spin-1/2 ladders are coupled through antiferromagnetic Ising interactions. The model hosts a quantum phase trans…
Reweight-annealing method for evaluating the partition function via quantum Monte Carlo calculations
Yi-Ming Ding, Jun-Song Sun, Nvsen Ma +3
Efficient and accurate algorithm for partition function, free energy and thermal entropy calculations is of great significance in statistical physics and quantum many-body physics.…
Sampling reduced density matrix to extract fine levels of entanglement spectrum and restore entanglement Hamiltonian
Bin-Bin Mao, Yi-Ming Ding, Zhe Wang +2
The reduced density matrix (RDM) plays a key role in quantum entanglement and measurement, as it allows the extraction of almost all physical quantities related to the reduced degr…
Exploring the topological sector optimization on quantum computers
Yi-Ming Ding, Yan-Cheng Wang, Shi-Xin Zhang +1
Optimization problems are the core challenge in many fields of science and engineering, yet general and effective methods are scarce for searching optimal solutions. Quantum comput…
Relevant long-range interaction of the entanglement Hamiltonian emerges from a short-range gapped system
Chuhao Li, Rui-Zhen Huang, Yi-Ming Ding +3
Beyond the Li-Haldane-Poilblanc conjecture, we find the entanglement Hamiltonian (EH) is actually not closely similar to the original Hamiltonian on the virtual edge. Unexpectedly,…
