Phys.org  August 3, 2022 Predicting the properties of a molecule or material requires calculating the collective behavior of its electrons because the electrons can become “quantum mechanically” entangled with one another. The entangled web of connections becomes tricky for even the most powerful computers to unravel directly for any system with more than a handful of particles. An international team of researchers (USA – Res. org., Switzerland) created a way to simulate entanglement by adding to their computations extra “ghost” electrons that interact with the system’s actual electrons. The behavior of the added electrons is controlled by neural network. The […]
