Rewriting Quantum Mechanics

Authors: George Rajna

Working as a hobby alongside their jobs in the Finnish government, and Lindgren's Ph.D. work in systems analysis at Aalto, the researchers devised a new method for expressing the laws of quantum mechanics using stochastic methods, a type of mathematics that deals with random chance and probability. [49] Quantum mechanics and the general theory of relativity form the bedrock of the current understanding of physics-yet the two theories don't seem to work together. [48] A groundbreaking study conducted by researchers from the National University of Singapore (NUS) has revealed a method of using quantum mechanical wave theories to "lock" heat into a fixed position. [47] Researchers at the University of Konstanz have recently carried out a study exploring the quantum states of light and vacuum fluctuations, as well as their interplay with time. [46] Physicists at the University of Innsbruck are proposing a new model that could demonstrate the supremacy of quantum computers over classical supercomputers in solving optimization problems. [45] Using data from the CMS experiment there, the researchers studied the entropy resulting from entanglement within the proton. [44] A German-Austrian research team is now presenting the largest entangled quantum register of individually controllable systems to date, consisting of a total of 20 quantum bits. [43] Neill is lead author of the group's new paper, "A blueprint for demonstrating quantum supremacy with superconducting qubits," now published in the journal Science. [42] Physicists at ETH Zurich have now demonstrated an elegant way to relax this intrinsic incompatibility using a mechanical oscillator formed by a single trapped ion, opening up a route for fundamental studies and practical uses alike.
