Measurement of Bell-type inequalities and quantum entanglement from $\Lambda$-hyperon spin correlations at high energy colliders

  author={Wenjie Gong and Ganesh Parida and Zhoudunming Tu and Raju Venugopalan},
Spin correlations of Λ-hyperons embedded in the QCD strings formed in high-energy collider experiments provide unique insight into their locality and entanglement features. We show from general considerations that while the Clauser-Horne-Shimony-Holt inequality is less stringent for such states, they provide a benchmark for quantum-to-classical transitions induced by varying i) the associated hadron multiplicity, ii) the spin of nucleons, iii) the separation in rapidity between pairs, and iv…

Testing Bell Inequalities at the LHC with Top-Quark Pairs.
It is shown how the measurement of a single observable can provide a test of the violation of a Bell inequality at the 98% C.L. with the statistical uncertainty of the data already collected at the Large Hadron Collider, and at the 99.99% L with the higher luminosity of the next run.
Role of boundary conditions in quantum computations of scattering observables
Quantum computing may offer the opportunity to simulate strongly-interacting field theories, such as quantum chromodynamics, with physical time evolution. This would give access to
Measurement of charged particle multiplicity distributions in DIS at HERA and its implication to entanglement entropy of partons
Charged particle multiplicity distributions in positron-proton deep inelastic scattering at a centre-of-mass energy √ s = 319 GeV are measured. The data are collected with the H1 detector at HERA
Loophole-free Bell inequality violation using electron spins separated by 1.3 kilometres
The data imply statistically significant rejection of the local-realist null hypothesis and could be used for testing less-conventional theories, and for implementing device-independent quantum-secure communication and randomness certification.
Einstein-Podolsky-Rosen Paradox and Quantum Entanglement at Subnucleonic Scales.
An experimental test of entanglement is devised and carried out using data on proton-proton collisions from the Large Hadron Collider to provide a strong direct indication of quantumEntanglement at subnucleonic scales.
Observing the emergence of a quantum phase transition shell by shell.
The atomic simulator provides a way to study the emergence of collective phenomena and the thermodynamic limit, particle by particle, by observing the few-body precursor of a quantum phase transition from a normal to a superfluid phase.

A quantum strategy to compute the jet quenching parameter $$\hat{q}$$
Jet quenching, the modification of the properties of a QCD jet when the parton cascade takes place inside a medium, is an intrinsically quantum process, where color coherence effects play an
