Moiré phonons and impact of electronic symmetry breaking in twisted trilayer graphene
Rhine Samajdar, Yanting Teng, Mathias S. Scheurer
Twisted trilayer graphene is a particularly promising moiré superlattice system, due to its tunability, strong superconductivity, and complex electronic symmetry breaking. Motivat…
Observable Estimation in the Absence of Classical Verification
Samantha V. Barron, Bradley Mitchell, Vinay Tripathi +45
The paper proposes a framework to independently validate observable estimates from quantum computers when classical benchmarks are unavailable, using experiments such as the operat…
Photon--Matter Quantum Correlations in Spontaneous Raman Scattering
Kai Shinbrough, Yanting Teng, Bin Fang +2
We develop a Hamiltonian formalism to study energy and position/momentum correlations between a single Stokes photon and a single material excitation that are created as a pair in…
Pauli Propagation: A Computational Framework for Simulating Quantum Systems
Manuel S. Rudolph, Tyson Jones, Yanting Teng +2
Classical methods to simulate quantum systems are not only a key element of the physicist's toolkit for studying many-body models but are also increasingly important for verifying…
Unquantized thermal Hall effect in quantum spin liquids with spinon Fermi surfaces
Yanting Teng, Yunchao Zhang, Rhine Samajdar +2
Recent theoretical studies have found quantum spin liquid states with spinon Fermi surfaces upon the application of a magnetic field on a gapped state with topological order. We in…
Derandomized shallow shadows: Efficient Pauli learning with bounded-depth circuits
Katherine Van Kirk, Christian Kokail, Jonathan Kunjummen +7
Efficiently estimating large numbers of non-commuting observables is an important subroutine of many quantum science tasks. We present the derandomized shallow shadows (DSS) algori…
Classifying topological neural network quantum states via diffusion maps
Yanting Teng, Subir Sachdev, Mathias S. Scheurer
We discuss and demonstrate an unsupervised machine-learning procedure to detect topological order in quantum many-body systems. Using a restricted Boltzmann machine to define a var…
Leveraging Symmetry Merging in Pauli Propagation
Yanting Teng, Su Yeon Chang, Manuel S. Rudolph +1
We introduce a symmetry-adapted framework for simulating quantum dynamics based on Pauli propagation. When a quantum circuit possesses a symmetry, many Pauli strings evolve redunda…
Learning topological states from randomized measurements using variational tensor network tomography
Yanting Teng, Rhine Samajdar, Katherine Van Kirk +5
Learning faithful representations of quantum states is crucial to fully characterizing the variety of many-body states created on quantum processors. While various tomographic meth…
Emergent gauge theories and topological excitations in Rydberg atom arrays
Rhine Samajdar, Darshan G. Joshi, Yanting Teng +1
Strongly interacting arrays of Rydberg atoms provide versatile platforms for exploring exotic many-body phases and dynamics of correlated quantum systems. Motivated by recent exper…
Phonon Hall viscosity from phonon-spinon interactions
Yunchao Zhang, Yanting Teng, Rhine Samajdar +2
Motivated by experimental observations, Samajdar et al. [Nature Physics 15, 1290 (2019)] have proposed that the insulating Neel state in the parent compounds of the cuprates is pro…
