Symmetry charges on reduced phase space and BMS algebra
Muxin Han, Zichang Huang, Hongwei Tan
This paper studies the reduced phase space formulation (relational formalism) of gravity coupling to the Brown-Kucha\v r dust for asymptotic flat spacetimes. A set of boundary cond…
Spinfoam on Lefschetz Thimble: Markov Chain Monte-Carlo Computation of Lorentzian Spinfoam Propagator
Muxin Han, Zichang Huang, Hongguang Liu +2
We compute numerically the Lorentzian Engle-Pereira-Rovelli-Livine (EPRL) spinfoam propagator on a 4-simplex, by adapting the methods of Lefschetz thimble and Markov Chain Monte-Ca…
Observation of Two-Vertex Four-Dimensional Spin Foam Amplitudes with a 10-qubit Superconducting Quantum Processor
Pengfei Zhang, Zichang Huang, Chao Song +8
Quantum computers are an increasingly hopeful means for understanding large quantum many-body systems bearing high computational complexity. Such systems exhibit complex evolutions…
Numerical computations of next-to-leading order corrections in spinfoam large- asymptotics
Muxin Han, Zichang Huang, Hongguang Liu +1
We numerically study the next-to-leading order corrections of the Lorentzian Engle-Pereira-Rovelli-Livine (EPRL) 4-simplex amplitude in the large- expansions. We perform large-$…
Efficient Simulation of Loop Quantum Gravity -- A Scalable Linear-Optical Approach
Lior Cohen, Anthony J. Brady, Zichang Huang +4
The problem of simulating complex quantum processes on classical computers gave rise to the field of quantum simulations. Quantum simulators solve problems, such as Boson sampling,…
Emergent 4-dimensional linearized gravity from spin foam model
Muxin Han, Zichang Huang, Antonia Zipfel
Spin Foam Models (SFMs) are covariant formulations of Loop Quantum Gravity (LQG) in 4 dimensions. This work studies the perturbations of SFMs on a flat background. It demonstrates…
