Exponential-in- cost reduction of product-formula-based quantum simulations of quantum chromodynamics
Zohreh Davoudi, Jesse R. Stryker
Quantum algorithms for simulating quantum chromodynamics (QCD) have matured steadily since the pioneering work of Byrnes and Yamamoto [PRA 73, 022328 (2006)]. The most popular stra…
String-breaking statics and dynamics in a (1+1)D SU(2) lattice gauge theory
Navya Gupta, Emil Mathew, Saurabh V. Kadam +5
String breaking is at the core of hadronization models of relevance to particle colliders. Yet, studies of string-breaking dynamics rooted in quantum chromodynamics remain fundamen…
Loop-string-hadron approach to SU(3) lattice Yang-Mills theory, II: Operator representation for the trivalent vertex
Saurabh V. Kadam, Aahiri Naskar, Indrakshi Raychowdhury +1
This work is the second installment of a series on the loop-string-hadron (LSH) approach to SU(3) lattice Yang-Mills theory. Here, we present the infinite-dimensional matrix repres…
Shearing approach to gauge-invariant Trotterization
Jesse R. Stryker
Universal quantum simulations of gauge field theories are exposed to the risk of gauge symmetry violations when it is not known how to compile the desired operations exactly using…
Loop-string-hadron approach to SU(3) lattice Yang-Mills theory: I. Hilbert space of a trivalent vertex
Saurabh V. Kadam, Aahiri Naskar, Indrakshi Raychowdhury +1
The construction of gauge invariant states of SU(3) lattice gauge theories has garnered new interest in recent years, but implementing them is complicated by the need for SU(3) Cle…
Tensor-network toolbox for probing dynamics of non-Abelian gauge theories
Emil Mathew, Navya Gupta, Saurabh V. Kadam +4
Tensor-network methods enable probing dynamics of strongly interacting quantum many-body systems, including gauge theories, via Hamiltonian simulation, hence bypassing sign problem…
