Measurement, whilst being physically fundamental, is also fundamentally physical. Classical interferometric measurements suffer from physical limitations where the shot noise limit forms an upper bound of n on a phase shift Δφ that can be resolved, with √n being the average number of photons detected, making their applicability in modern nanoscale experiments quite restricted. Exotic quantum states such as maximally entangled NOON states (|N0≫A;B +|0N≫A;B)/√2, where N is the number of entangled photons are of particular importance as they have repeatedly been shown to exhibit phase super-resolution [1,2]. Interesting post selection schemes  and time-reversed detection schemes  have been investigated for phase estimation using NOON states. These methods are inherently non-deterministic at the preparation  or measurement  stage and thus do not optimise resources, for instance the number of photons passing through the sample greatly exceeds those used in the measurement.
