One For All Five Entangled Photons Collectively Choose A Path To Follow
Quantum entanglement, a phenomenon by which two or more particles share correlated properties through some instantaneous link, is tricky business. The quantum-mechanical bond entangling two particles is so delicate, it can be broken by any number of outside perturbations. Try entangling three particles, and the system becomes just that much more vulnerable to interference. Nevertheless, physicists strive to entangle ever larger systems, with the ultimate goal of harnessing quantum effects in large numbers of particles for computation, communication, or ultraprecise measurements....
