Frequency shifts do not imply quantum entanglement (2022) (benbrubaker.com)
I’ve somehow become the go-to twitter critic (jointly with Douglas Natelson, a Rice University physics professor with an excellent blog) of a recent unpublished manuscript that has generated a lot of premature press coverage. The authors of this paper claim to have demonstrated quantum entanglement between a superconducting qubit — a special kind of electrical circuit that exhibits quantum behavior — and a remarkably hardy little creature called a tardigrade.
Scientists observe 'negative time' in quantum experiments (phys.org)
Scientists have long known that light can sometimes appear to exit a material before entering it—an effect dismissed as an illusion caused by how waves are distorted by matter.
Teaching quantum physics in schools: Experts encourage focus on 2 state systems (phys.org)
A team of physics educators from Italy, Hungary, Slovenia and Germany is focusing on a new approach to teaching quantum physics in schools.
Quantum scars make their mark in graphene (nature.com)
By patterning an ultrathin layered structure with tiny wells, physicists have created and imaged peculiar states known as quantum scars — revealing behaviour that could be used to boost the performance of electronic devices.
