The invention regards a measurement based photonic quantum computing system comprising an optical input generator configured for receiving first optical paired inputs, and second optical paired inputs, inducing a first predefined relative time delay into each optical paired inputs for making one mode of the first and one mode of the second optical paired inputs into coexisting optical inputs, representing a logic level of the quantum computing system, a delocalized measurement architecture configured for optically interfering coexisting optical inputs for generating intermediate outputs, optically interfering by first and second variable path-couplers for each intermediate output a first mode of the intermediate outputs to a second mode of first or second neighboring intermediate outputs, respectively, for generating interfered outputs, and detecting by two optical detectors, preferably homodyne optical detectors, each mode of the intermediate outputs and the interfered outputs, such that the delocalized measurement architecture is configured for gate implementation of the quantum computing system.
