Quantum Entanglement

Quantum physics is fascinating.

Quantum Entanglement is the phenomenon where the quantum state of each particle in a group cannot be described independently of the state of the others, even when the particles are separated by an astronomical large distance. The topic of quantum entanglement is at the heart of the disparity between classical physics and quantum physics: entanglement is a primary feature of quantum mechanics not present in classical mechanics.

Measurements of physical properties such as position, momentum, spin, and polarization performed on entangled particles can, in some cases, be found to be perfectly correlated. For example, if a pair of entangled particles is generated such that their total spin is known to be zero, and one particle is found to have clockwise spin on a first axis, then the spin of the other particle, measured on the same axis, is found to be anticlockwise. However, this behavior gives rise to seemingly paradoxical effects: any measurement of a particle's properties results in an apparent and irreversible wave function collapse of that particle and changes the original quantum state. With entangled particles, such measurements affect the entangled system as a whole.

#Pioneering female #Chinese #American physicist Chien-Shiung Wu, who worked with Robert #Oppenheimer on the #ManhattanProject, was also the first to confirm #QuantumEntanglement – just 14 years after Albert #Einstein questioned the phenomenon. The largely forgotten achievement was included in a profile of Wu, one of the most influential experimental physicists of the 20th century, published in the December 2024 issue of Physics Today.

Wu is also believed to have been the only Chinese scientist involved in the Manhattan Project, the World War II initiative to develop an #AtomicBomb led by Oppenheimer, who affectionately referred to her as Jiejie, which means elder sister, the article said.

Wu’s experiment – detailed in a paper published in 1950 – was conducted before the #scientific community had fully grasped the significance of quantum entanglement, the article noted.
