Quantum entanglement is a mysterious phenomenon of quantum mechanics that appears not only in low-energy atomic physics, but also in high-energy collision physics. In recent years, the effects of quantum entanglement have been predicted or observed in some of the representative high-energy collisions, such as heavy ion collisions, the production of top quark pairs, and the decay of the Higgs...
Signatures involving the Higgs boson from quantum corrections and interference effects, can be precisely calculated using Quantum Field Theory (QFT) at the LHC.
These phenomena position the Higgs as a crucial tool for probing the fundamental nature of quantum physics in high-energy physics. In this talk, we will explore how one can understand the quantum formalism by rejecting the LHVM...
A new sub-field has exploded onto the particle physics scene: testing fundamental features of quantum mechanics in collider experiments. A prominent initial result is the ATLAS Collaboration’s observation of quantum entanglement between top-quark pairs, the first measurement of entanglement between free quarks, and the highest energy lab-based quantum information experiment to date....
In quantum mechanics, a system is said to be entangled if its quantum state cannot be described as a simple superposition of the states of its constituents. If two particles are entangled, we cannot describe one of them independently of the other, even if the particles are separated by a very large distance. When we measure the quantum state of one of the two particles, we instantly know the...
