Mixed-State Phase Transitions in Measurement-Dressed Imaginary-Time Evolution
Yi-Ming Ding, Zenan Liu, Xu Tian +3
The paper introduces measurement-dressed imaginary-time evolution (MDITE), which interleaves imaginary-time filtering with local projective measurements, and studies how this compe…
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…
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…
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…
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 rati…
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…
