• Abstract: Wave guides for classical electromagnetic fields can realize the quantum evolution of the wave function for a system of qubits. Phase shifts, switches and beam splits allow for the construction of arbitrary quantum gates. They can act at once on a large number of qubits. For this correlation based photonic quantum computer the channels of the wave guides represent basis states of a multi-qubit system rather than individual qubits. The classical probabilistic implementation of a quantum evolution sheds new light on the foundations of quantum mechanics.
