New Principle May Help Explain Why Nature Is Quantum (image) Centre for Quantum Technologies at the National University of Singapore Share Print E-Mail Caption A principle of 'accepting the facts' implies that a quantum bit (typically pictured as a 'Bloch ball') can look like a sphere but not like a polyhedron. Polyhedral bits have been linked to theories of discrete spacetime. By ruling out various alternative theories of nature, the principle may help to explain why the world is quantum.
