Background: Quantum information science and technology (QIST) has progressed significantly in the last decade, such that it is no longer solely domain of research labs, but now beginning to be developed for, applied in, industrial applications products. With emergence this new quantum industry, a workforce trained QIST skills knowledge needed. Research Questions: To help support education training workforce, universities colleges require type jobs available for their students what degrees...

Motivated by multiple phenomenological considerations, we perform the first search for existence of a $\overline{b}\overline{b}bb$ tetraquark bound state with mass below lowest noninteracting bottomonium-pair threshold using first-principles lattice nonrelativistic QCD methodology. We use full $S$-wave color/spin basis operators in three ${0}^{++}$, ${1}^{+\ensuremath{-}}$ and ${2}^{++}$ channels. employ four gluon field ensembles at spacing values ranging from $a=0.06--0.12\text{ }\text{...

In the near-future noisy intermediate-scale quantum era of computing technology, applications will be limited to calculations very modest scales in terms number qubits used. The need represent numeric quantities using resources leads digitization errors which must taken into account. As a first step towards simulations realistic high-energy physics problems, we use ensembles SU(2) lattice gauge fields generated with standard classical explore effects digitizing elements group finite set.

We describe a numerical study of the potential energy landscape for two-dimensional XY model (with no disorder), considering up to 100 spins and central processing unit graphics implementations local optimization, focusing on minima saddles index one (transition states). examine both periodic anti-periodic boundary conditions, show that number stationary points located increases exponentially with increasing lattice size. The corresponding disconnectivity graphs exhibit funneled landscapes;...

The application of numerical techniques to the study energy landscapes large systems relies on sufficient sampling stationary points. Since number points is believed grow exponentially with system size, we can only sample a small fraction. We investigate interplay between this restricted size and physical features potential landscape for two-dimensional XY model in absence disorder up N = 100 spins. Using an eigenvector-following technique, numerically compute given Hessian index I all...

Sampling the stationary points of a complicated potential energy landscape is challenging problem. Here, we introduce sampling method based on relaxation from highest index Hessian matrix. We illustrate how this approach can find all for potentials or Hamiltonians bounded above, which includes large class important spin models, and show that it far more efficient than previous methods. For unbounded part still in finding minima transition states, are usually primary focus attention atomistic systems.

QCD exhibits complex dynamics near S-wave two-body thresholds. For light mesons, we see this in the failure of quark models to explain $f_0(500)$ and $K_0^*(700)$ masses. charmonium, an unexpected $X(3872)$ state appears at open charm threshold. In heavy-light systems, analogous threshold effects appear for lowest $J^P = 0^+$ $1^+$ states $D_s$ $B_s$ systems. Here describe how lattice can be used understand these by smoothly varying strange-quark mass when studying Small perturbations around...
