“…In particular, efforts toward image‐preserving frequency conversion and amplification are being pursued by numerous nonlinear optics groups around the world. With recent advances in imaging based on structured illumination, the development of suitable frequency converters and mode analyzers could also extend the wavelength range for coherent imaging schemes based on structured wave fronts.…”

Quantum imaging is a multifaceted field of research that promises highly efficient imaging in extreme spectral ranges as well as ultralow‐light microscopy. Since the first proof‐of‐concept experiments over 30 years ago, the field has evolved from highly fascinating academic research to the verge of demonstrating practical technological enhancements in imaging and microscopy. Here, the aim is to give researchers from outside the quantum optical community, in particular those applying imaging technology, an overview of several promising quantum imaging approaches and evaluate both the quantum benefit and the prospects for practical usage in the near future. Several use case scenarios are discussed and a careful analysis of related technology requirements and necessary developments toward practical and commercial application is provided.

“…This drawback prevents us from building up a high fidelity interface between two photons in the different frequency domains. Some works try to balance conversion efficiency for different L, for example, using a short nonlinear crystal [24], or optimizing input spatial profile [23], however, it reduces the overall CE.…”

“…During this process, the energy (ω P + ω I = ω V ), the momentum (k P + k I + 2π/Λ = k V ), and the OAM (L P + L I = L V ) are all in conservations. For a qudit defined in a subspace of ∈ {− [d/2] , ..., [d/2]}, the entire conversion process can be described via the effective Hamiltonian [2,4,23]:…”

In high dimensional quantum communication networks, quantum frequency converter (QFC) is indispensable as an interface in the frequency domain. For example, Much QFCs have been built to link atomic memories and fiber channels. However, Almost all of QFCs work in two-dimensional space. It is still a key challenge to construct a high quality QFC for some complex quantum states, e.g., a high dimensional single-photon state that refers to a qudit. Here, we firstly propose a highdimensional QFC for orbital angular momentum-based qudit via sum frequency conversion with a flat top beam pump. As a demonstration, we realize quantum frequency conversions for a qudit from infrared to visible. Based on the qudit quantum state tomography, we get the fidelities are 98.29%, 97.42% and 86.75% for qudit in 2,3, and 5 dimensions, respectively. The demonstration is very promising for constructing a high capacity quantum communication network.

“…For optical signal processing and detection, NLO techniques can offer significant advantages over their linear-optics counterparts 5,16,17 , as demonstrated repeatedly in temporal mode-selective frequency conversion 18–24 , lossless photon shaping 25 , spiral phase contrast imaging of the edges 26 , and field-of-view enhancement 8,27 . To capitalize on the rich spatial features of light, frequency upconversion has been utilized for mode-selective detection of spatially orthogonal signals in few-mode waveguides 7,28 , and more recently in nonlinear crystals to selectively convert overlapping Laguerre-Gaussian (LG) and Hermite-Gaussian (HG) modes 29,30 .…”

We experimentally study a nonlinear optical approach to selective manipulation and detection of structured images mixed with turbulent noise. Unlike any existing adaptive-optics method by applying compensating modulation directly on the images, here we account for the turbulence indirectly, by modulating only the pump driving the nonlinear process but not the images themselves. This indirect approach eliminates any signal modulation loss or noise, while allowing more flexible and capable operations. Using specifically sum frequency generation in a lithium niobate crystal, we demonstrate selective upconversion of Laguerre-Gaussian spatial modes mixed with turbulent noise. The extinction reaches ~40 dB without turbulence, and maintains ~20 dB in the presence of strong turbulence. This technique could find utilities in classical and quantum communications, compressive imaging, pattern recognition, and so on.
