Non-stabilizerness and entanglement in -dimensional SU(2) lattice gauge theory using tensor networks
Raghav G. Jha, Jaber I. Taher, Muhammad Asaduzzaman +3
We study non-stabilizerness (magic) in the ground state of -dimensional Hamiltonian lattice gauge theory with matter, formulated in the dressed-site basis i…
Efficient computation of real-time correlators using Pauli Propagation
Alexander F. Kemper, Raghav G. Jha, Arnab Bachhar +3
Pauli propagation has shown promise for classically simulating quantum dynamics by evolving observables directly in the Heisenberg picture. In this work, we investigate its use for…
Ground state preparation of random all-to-all Hamiltonians using ADAPT-VQE
Sabhyata Gupta, Bharath Sambasivam, Sophia E. Economou +3
The ground state of random Hamiltonians with all-to-all interactions such as the quantum Sherrington-Kirkpatrick (SK) model and the Sachdev-Ye-Kitaev (SYK) model follow volume-law…
Magic and entanglement in 1+1-dimensional SU(2) lattice gauge theory
Raghav G. Jha, Goksu C. Toga, Jaber I. Taher +2
Entanglement and non-stabilizerness (magic) quantify two distinct departures of quantum systems from classical description: the former measures non-local correlations, while the la…
Quantum simulation of massive Thirring and Gross--Neveu models for arbitrary number of flavors
Bojko N. Bakalov, Joao C. Getelina, Raghav G. Jha +2
The study of fermionic quantum field theories is an important problem for realizing the standard model of particle physics on a quantum computer. As a step towards this goal, we co…
Hybrid continuous-discrete-variable quantum computing: a guide to utility
A. F. Kemper, Antonios Alvertis, Muhammad Asaduzzaman +24
Quantum computing has traditionally centered around the discrete variable paradigm. A new direction is the inclusion of continuous variable modes and the consideration of a hybrid…
Thermal state preparation of the SYK model using a variational quantum algorithm
Jack Y. Araz, Raghav G. Jha, Felix Ringer +1
We study the preparation of thermal states of the dense and sparse Sachdev-Ye-Kitaev (SYK) model using a variational quantum algorithm for Majorana fermions over a…
Hamiltonian simulation of minimal holographic sparsified SYK model
Raghav G. Jha
The circuit complexity for Hamiltonian simulation of the sparsified SYK model with Majorana fermions and (quartic interactions) which retains holographic features (referr…
Sachdev-Ye-Kitaev model on a noisy quantum computer
Muhammad Asaduzzaman, Raghav G. Jha, Bharath Sambasivam
We study the SYK model -- an important toy model for quantum gravity on IBM's superconducting qubit quantum computers. By using a graph-coloring algorithm to minimize the number of…
Continuous variable quantum computation of the model in 1+1 dimensions
Raghav G. Jha, Felix Ringer, George Siopsis +1
We formulate the non-linear sigma model in 1+1 dimensions as a limit of a three-component scalar field theory restricted to the unit sphere in the large squeezing limit. Thi…
Notes on Quantum Computation and Information
Raghav G. Jha
We discuss fundamentals of quantum computing and information - quantum gates, circuits, algorithms, theorems, error correction, and provide collection of QISKIT programs and exerci…
