Abstract: In this article we describe the characteristics of a large integrated linear optical device containing Mach-Zehnder interferometers and describe its potential use as a physically unclonable function. We propose that any tunable interferometric device of practical scale will be intrinsically unclonable and will possess an inherent randomness that can be useful for many practical applications. The device under test has the additional use-case as a general-purpose photonic manipulation tool, with various applications based on the experimental results of our prototype. Once our tunable interferometric device is set to work as a physically unclonable function, we find that there are approximately 6.85x10E35 challenge-response pairs, where each challenge can be quickly reconfigured by tuning the interferometer array for subsequent challenges.

Measurement-induced entanglement and teleportation on a noisy quantum processor [105.44548669906976]
We investigate measurement-induced quantum information phases on up to 70 superconducting qubits. We use a duality mapping, to avoid mid-circuit measurement and access different manifestations of the underlying phases. Our work demonstrates an approach to realize measurement-induced physics at scales that are at the limits of current NISQ processors.

Two-colour spectrally multimode integrated SU(1,1) interferometer [77.34726150561087]
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.

Interferobot: aligning an optical interferometer by a reinforcement learning agent [118.43526477102573]
We train an RL agent to align a Mach-Zehnder interferometer, based on images of fringes acquired by a monocular camera. The agent is trained in a simulated environment, without any hand-coded features or a priori information about the physics. Thanks to a set of domain randomizations simulating uncertainties in physical measurements, the agent successfully aligns this interferometer without any fine tuning.
