- Abstract: We present an integrated design to precisely measure optical frequency using
weak value amplification with a multi-mode interferometer. The technique
involves introducing a weak perturbation to the system and then post-selecting
the data in such a way that the signal is amplified without amplifying the
technical noise, as has previously been demonstrated in a free-space setup. We
demonstrate the advantages of a Bragg grating with two band gaps for obtaining
simultaneous, stable high transmission and high dispersion. We numerically
model the interferometer in order to demonstrate the amplification effect. The
device is shown to have advantages over both the free-space implementation and
other methods of measuring optical frequency on a chip, such as an integrated
Mach-Zehnder interferometer.

We introduce an ultra-sensitive interferometric protocol that combines weak value amplification with traditional interferometry.
This WVA+interferometry protocol uses weak value amplification of the relative delay between two paths to enhance the interferometric sensitivity.
We experimentally demonstrate that the signal-to-noise ratio can be improved by one to three orders of magnitude.

We demonstrate that this scheme is far more powerful and can also protect a single (or even an ensemble) qubit's energy levels from noise which depends on both time and space.

Low-noise microwave amplification is crucial for detecting weak signals in quantum technologies and radio astronomy.
Current amplifiers do not satisfy all these requirements, severely limiting the scalability of superconducting quantum devices.
Here, we demonstrate the feasibility of building a near-ideal quantum amplifier using a homogeneous Josephson junction array and the non-trivial topology of its dynamics.

We develop and investigate an integrated multimode two-colour SU (1,1) interferometer that operates in a supersensitive mode.
By ensuring a proper design of the integrated platform, we suppress dispersion and thereby significantly increase the visibility of the interference pattern.
We demonstrate that such an interferometer overcomes the classical phase sensitivity limit for wide parametric gain ranges, when up to $3*104$ photons are generated.

tuning the interferometer to be as unprojective as possible was associated with an increase in the quantum efficiency of our readout relative to the optimum setting for projective measurement.
