Resolution of Quantum Imaging with Undetected Photons
Quantum 6, 646 (2022).
https://doi.org/10.22331/q-2022-02-09-646Quantum imaging with undetected photons is a recently introduced technique that goes significantly beyond what was previously possible. In this technique, images are formed without detecting the light that interacted with the object that is imaged. Given this unique advantage over the existing imaging schemes, it is now of utmost importance to understand its resolution limits, in particular what governs the maximal achievable spatial resolution. We show both theoretically and experimentally that the momentum correlation between the detected and undetected photons governs the spatial resolution — a stronger correlation results in a higher resolution. In our experiment, the momentum correlation plays the dominating role in determining the resolution compared to the effect of diffraction. We find that the resolution is determined by the wavelength of the undetected light rather than the wavelength of the detected light. Our results thus show that it is in principle possible to obtain resolution characterized by a wavelength much shorter than the detected wavelength.

Chainalysis report reveals signs of significant wash trading activity involving NFTs.
A new report issued by Chainalysis, one of the leading auditing and tracking firms in crypto and blockchain, has detected “significant” wash activity in the NFT market. These activities aim to make an NFT more valuable by giving the appearance of previous sales. Using blockchain analysis, the company was able to detect 262 users that have sold […]
