Physical systems evolve at a particular speed, which depends on various factors including the system's so-called topological structure (i.e., spatial properties that are preserved over time despite any physical changes that ...
"Suppose you knew everything there was to know about a water molecule—the chemical formula, the bond angle, etc.," says Joseph Thywissen, a professor in the Department of Physics and a member of the Centre for Quantum Information ...
