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…
RedCarD: A Quantum Assisted Algorithm for Fixed-Depth Unitary Synthesis via Cartan Decomposition
Omar Alsheikh, Efekan Kökcü, Bojko N. Bakalov +1
A critical step in developing circuits for quantum simulation is to synthesize a desired unitary operator using the circuit building blocks. Studying unitaries and their generators…
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…
Classification of dynamical Lie algebras generated by spin interactions on undirected graphs
Efekan Kökcü, Roeland Wiersema, Alexander F. Kemper +1
We provide a classification of all dynamical Lie algebras generated by 2-local spin interactions on undirected graphs. Building on our previous work where we provided such a classi…
Geometric Quantum Machine Learning with Horizontal Quantum Gates
Roeland Wiersema, Alexander F. Kemper, Bojko N. Bakalov +1
In the current framework of Geometric Quantum Machine Learning, the canonical method for constructing a variational ansatz that respects the symmetry of some group action is by for…
Classification of dynamical Lie algebras for translation-invariant 2-local spin systems in one dimension
Roeland Wiersema, Efekan Kökcü, Alexander F. Kemper +1
Much is understood about 1-dimensional spin chains in terms of entanglement properties, physical phases, and integrability. However, the Lie algebraic properties of the Hamiltonian…
A Lie Algebraic Theory of Barren Plateaus for Deep Parameterized Quantum Circuits
Michael Ragone, Bojko N. Bakalov, Frédéric Sauvage +4
Variational quantum computing schemes train a loss function by sending an initial state through a parametrized quantum circuit, and measuring the expectation value of some operator…
