The many-worlds interpretation is an interpretation of quantum mechanics that asserts the objective reality of the universal wavefunction and denies the actuality of wavefunction collapse. Many-worlds implies that all possibl... |

Monstrosity of Quantum Mechanics 4: Quantum Computers
The belief of the modern physicist that the linear multi-dimensional Schrödinger equation
describes the quantum world of atoms and molecules, has led to the idea of the quantum computer:

Complex numbers are fundamental and natural and QM can't work without them - o... |
