Magnetic switch turns strange quantum property on and off. A research team has developed the first switch that turns on and off a quantum behavior called the Berry phase. The discovery promises to provide new insight into the fundamentals of quantum theory and may lead to new quantum electronic devices. Ref. Source 2y.
Single photon reveals quantum entanglement of 16 million atoms. Quantum theory predicts that a vast number of atoms can be entangled and intertwined by a very strong quantum relationship even in a macroscopic structure. Until now, experimental evidence has been mostly lacking, despite recent advances have shown the entanglement of 2,900 atoms. Scientists recently reengineered their data processing, demonstrating that 16 million atoms were entangled in a one-centimeter crystal. Source 4g.
Quantum physicists achieve entanglement record. Entanglement is of central importance for the new quantum technologies of the 21st century. A research team is now presenting the largest entangled quantum register of individually controllable systems to date, consisting of a total of 20 quantum bits. The physicists are pushing experimental and theoretical methods to the limits of what is currently possible. Source 8v.
