Simulating one-dimensional quantum chromodynamics on a quantum computer: Real-time evolutions of tetra- and pentaquarks
Bibliographic record
Abstract
Quantum chromodynamics (QCD)---the theory of quarks and gluons---has been studied for decades, but it is yet to be fully understood. A recent example is the prediction and experimental discovery of tetraquarks, which opened a new research field. Crucially, numerous unsolved questions regarding the standard model can exclusively be addressed by nonperturbative calculations. Quantum computers can solve problems for which well-established QCD methods are inapplicable, such as real-time evolution. We take a key step in exploring this possibility by designing a real-time evolution of tetraquark and pentaquark physics in one-dimensional SU(3) gauge theory. We also perform an experiment on a superconducting quantum computer demonstrating an elementary cell consisting of two staggered sites containing quarks and antiquarks with all three colors. This experiment represents an exciting step in quantum computation involving quarks with the gauge group of QCD.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
