Quantum observation scheme universally identifying causalities from correlations
, 2020 It has long been recognized as a difficult problem to determine whether the observed statistical correlation between two classical variables arise from causality or from common causes.

Noise-robust ground state energy estimates from deep quantum circuits [PDF]
Quantum, 2023 In the lead up to fault tolerance, the utility of quantum computing will be determined by how adequately the effects of noise can be circumvented in quantum algorithms. Hybrid quantum-classical algorithms such as the variational quantum eigensolver (VQE)

Observation of quantum entanglement in top quark pair production in proton–proton collisions at s=13 TeV [PDF]
Reports on progress in physics. Physical SocietyEntanglement is an intrinsic property of quantum mechanics and is predicted to be exhibited in the particles produced at the Large Hadron Collider. A measurement of the extent of entanglement in top quark-antiquark ( tt¯) events produced in proton–proton

Observation of spin-space quantum transport induced by an atomic quantum point contact
Nature Communications, 2021 Cold atoms have recently become a versatile platform for the study of quantum transport phenomena. Here the authors realize an alternative experimental scheme for quantum transport with cold atoms, by using spin-dependent impurity scattering in a spinful

Observation of string breaking on a (2 + 1)D Rydberg quantum simulator [PDF]
NatureLattice gauge theories (LGTs) describe a broad range of phenomena in condensed matter and particle physics. A prominent example is confinement, responsible for bounding quarks inside hadrons such as protons or neutrons1.
