“…Quantum imaging [1-3] established itself as a major pillar of the rapidly expanding field of quantum technologies [4,5]. Among the techniques found in quantum imaging we can cite ghost imaging [6][7][8][9], imaging with undetected photons [10][11][12][13][14], sub-shot-noise quantum imaging [15][16][17] and finally, interaction-free measurement (IFM) imaging [18,19]. These quantum imaging techniques are not necessarily separated, as shown in reference [20], where interaction-free and ghost imaging techniques have been jointly used to harvest their full potential.…”

“…More than two decades after this "mind-boggling experiment" [25], the now famous imaging with undetected photons was performed [10]. Further developments included infrared spectroscopy with visible photons [11], applications to semiconductor industry [12] and biological microscopy with undetected photons [13,14,26].…”

Quantum 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.

Spectroscopy is an important tool for probing the properties of materials, chemicals, and biological samples. We design a practical transmitter-receiver system that exploits entanglement to achieve a provable quantum advantage over all spectroscopic schemes based on classical sources. To probe the absorption spectra, modeled as a pattern of transmissivities among different frequency modes, we employ broadband signal-idler pairs in two-mode squeezed vacuum states. At the receiver side, we apply photodetection after optical parametric amplification. Finally, we perform a maximum likelihood decision test on the measurement results, achieving an error probability orders of magnitude lower than the optimum classical systems in various examples, including "wine tasting" and "drug testing" where real molecules are considered. In detecting the presence of an absorption line, our quantum scheme achieves the optimum performance allowed by quantum mechanics. The quantum advantage in our system is robust against noise and loss, which makes near-term experimental demonstration possible.
