- Title: Theoretical framework for real time sub-micron depth monitoring using
quantum inline coherent imaging
- Authors: Alexander Wainwright and Khaled Madhoun
- Abstract summary: Inline Coherent Imaging (ICI) is a reliable method for real-time monitoring of various laser processes, including keyhole welding, additive manufacturing, and micromachining.
The axial resolution is limited to greater than 2 mum making ICI unsuitable for monitoring submicron processes.
Advancements in Quantum Optical Coherence Tomography (Q OCT) has the potential to address this issue by achieving better than 1 mum depth resolution.

- Abstract: Inline Coherent Imaging (ICI) is a reliable method for real-time monitoring
of various laser processes, including keyhole welding, additive manufacturing,
and micromachining. However, the axial resolution is limited to greater than 2
{\mu}m making ICI unsuitable for monitoring submicron processes. Advancements
in Quantum Optical Coherence Tomography (QOCT), which uses a Hong-Ou-Mandel
(HOM) interferometer, has the potential to address this issue by achieving
better than 1 {\mu}m depth resolution. While time-resolved QOCT is slow,
Fourier domain QOCT (FD-QOCT) overcomes this limitation, enabling submicron
scale real-time process monitoring. Here we review the fundamentals of FD-QOCT
and QOCT and propose a Quantum Inline Coherent Imaging system based on FD-QOCT.
Using frequency entangled sources available today the system has a theoretical
resolution of 0.17 microns, making it suitable for submicron real-time process
monitoring.

We introduce a single-photon detector design operating in the microwave domain based on a weakly nonlinear metamaterial.
We show that the single-photon detection fidelity increases with the length of the metamaterial to approach one at experimentally realistic lengths.
In stark contrast to conventional photon detectors operating in the optical domain, the photon is not destroyed by the detection and the photon wavepacket is minimally disturbed.
