Quantum theory is often portrayed as a disruptive force, complicating everything that classical physics seemed to have figured out. Now, however, physicists at Lawrence Berkeley National Laboratory LBNL in the US have demonstrated that the two can work side-by-side, in a proof-of-principle study that shows how a quantum computer can complement a classical method of modelling high-energy particle collisions. Physicists use computer models to predict what happens to those particles by the time they reach a detector. In one such modelling technique, known as a parton shower, the assumption is that the particles that make it to the detector are the last step in a long cascade of particles and radiation that converted into one another after the initial collision. For this parton shower to include quantum features of particle interactions, however, the model needs to simultaneously consider all possible intermediate particles that could form between the initial and final particles — something that cannot be done by a classical computer algorithm, says Christian Bauer , a theoretical physicist at LBNL and co-author of the paper. In their study, which appears in Physical Review Letters , Bauer and colleagues created a quantum algorithm for the parton shower.The Physics Of Computer Science Video

Wolfram was educated at Eton CollegeThe Physics Of Computer Science left prematurely in John's College, Oxfordat age 17 but found lectures "awful", [18] and left in [32] without graduating [33] [34] to attend the California Institute of Technology the following year, where he received a PhD [35] in particle physics on 19 November at age Sciulli and Steven Frautschiand chaired by Richard D. As a young child, Wolfram had difficulties learning arithmetic. Wolfram, at the age of 15, began research in applied quantum field theory and particle physics and published scientific papers.
