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…
Depth analysis of the Quantum Approximate Optimization Algorithm with a Grover mixer
Bojko N. Bakalov, Dimitar Grantcharov
We study the Quantum Approximate Optimization Algorithm with a Grover mixer and independently sampled cost and mixing angles. Under a lattice condition on the cost values carried b…
Spin models with critical ground space degeneracy from Lie algebra relations
Andras Molnar, Efekan Kökcü, Norbert Schuch +1
We introduce an -symmetric spin model derived from the algebraic structure of : It is obtained as the nearest-neighbor parent Hamiltonian of a Mat…
Hybrid Qubit-Rotor Quantum Systems: Clifford Structure, Universal Control, and Applications
Dengyao Luo, Arvin Kushwaha, Mastawal Tirfe +1
A quantum rotor pairs a periodic angle with an integer-valued conjugate momentum, and occurs in molecular rotation, superconducting phase-charge circuits, and compact gauge…
Symmetry Constraints Regularize Neural Quantum State Learning
Turbasu Chatterjee, Manas Sajjan, Songbo Xie +4
Neural quantum states (NQS) offer highly expressive variational wavefunctions, but their optimization is frequently bottlenecked by redundant parameters and poorly conditioned land…
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…
