Invention:
This technology represents a step forward creating a decoherence-free optical quantum information processing and computing analog, which does not rely on the fragile quantum states but rather robust classical states. The inventors propose how to implement the universal set of quantum gates classical analogs in integrated optics by employing classical polarization states derived from the coherent states. This can potentially provide stable qubits analogs for quantum computing, thus potentially reducing the complexity and size of quantum computers. As the quantum qudit alternative authors proposed to apply classical orbital angular momentum (OAM) states.
