“…For example, with respect to quantum information processing, temporal distinguishability in HOM interference can be harnessed to prepare and characterize high-dimensional frequency entanglement [17,35,36]. With respect to quantum metrology, entanglement-assisted absorption spectroscopy based on quantum interference has been used to detect the absorptive properties of materials and molecules, which has the potential to provide quantum advantages in robustness against noise and loss [11,22,37]. In addition, entanglement-based optical coherence tomography have inspired many unique applications such as quantum sensing with undetected photons, which enables the manipulation and detection of photons by harnessing its parter photons with a completely different wavelength, in particular for commercial near-IR-OCT systems [38].…”

“…Since this QWKT establishes the connection between the time-energy domains of biphoton wavefunction, it is allowed to extract temporal information from spectral pattern (i.e., quantum optical coherence tomography [14,21]), or extract spectral information from temporal pattern (i.e., quantum interferometric spectroscopy [22]). Furthermore, threedimensional quantum tomography is also achievable with the assistance of spatiotemporal quantum interference [20].…”

Wiener-Khinchin theorem, the fact that the autocorrelation function of a time process has a spectral decomposition given by its power spectrum intensity, can be used in many disciplines. However, the applications based on a quantum counterpart of Wiener-Khinchin theorem that provides a translation between time-energy degrees of freedom of biphoton wavefunction still remains relatively unexplored. Here, we use a quantum Wiener-Khinchin theorem (QWKT) to state that two-photon joint spectral intensity and the cross-correlation of two-photon temporal signal can be connected by making a Fourier transform. The mathematically-defined QWKT is experimentally demonstrated in frequency-entangled two-photon Hong-Ou-Mandel (HOM) interference with the assistance of spectrally-resolved detection. We apply this method to spectral-domain quantum optical coherence tomography that detects thickness-induced optical delays in a transparent sample, and show that our method suffices to achieve great advantages in measurement precision within a wide dynamic range and capturing time over the conventional HOM interferometric schemes. These results may significantly facilitate the use of QWKT for quantum information processing and quantum interferometric spectroscopy.

“…Then, we present a robust and efficient entanglement-based absorption spectroscopy by using one of the entangled photons to interact with the target absorptive sample and exploiting the HOM interference at the detection side as shown in Figure 6 [125]. In our experiment, we use a pair of type-0 PPKTP crystals that are pumped with a ultra-narrow pump, broadband frequency entanglement arises quite naturally following the energy conservation.…”

Quantum interferences of entangled photons have engendered tremendous intriguing phenomena that lack any counterpart in classical physics. Hitherto, owing to the salient properties of quantum optics, quantum interference has been widely studied and provides useful tools that ultimately broaden the path towards ultra-sensitive quantum metrology, ranging from sub-shot-noise quantum sensing to high-resolution optical spectroscopy. In particular, quantum interferometric metrology is an essential requisite for extracting information about the structure and dynamics of photon-sensitive biological and chemical molecules. This article reviews the theoretical and experimental progress of this quantum interferometric metrology technology along with their advanced applications. The scope of this review includes Hong–Ou–Mandel interferometry with ultrahigh timing resolution, entanglement-assisted absorption spectroscopy based on a Fourier transform, and virtual-state spectroscopy using tunable energy-time entangled photons.

Fast Quantifier of High‐Dimensional Frequency Entanglement through Hong–Ou–Mandel Interference

High-dimensional frequency entanglement is an enabling resource in quantum technology due to its high information capacity and error resilience.A concise yet efficient method for precisely quantifying its dimensionality remains an open challenge, owing to the difficulties for performing required superposition measurements in energy-time domains, and the complexity associated with full quantum state tomography that scales unfavorably with dimensions. With the assistance of Hong-Ou-Mandel experiment that performs a Fourier transform between the entangled photons in terms of joint spectral intensities and the quantum interference in terms of biphoton temporal coincidences, the concept of Shannon dimensionality as a fast quantifier of bipartite continuous frequency entanglement is unlocked. This quantitative technique reveals the complete distribution of frequency entanglement but without suffering from any limitation of modal capacity of the detection geometry. These results may significantly facilitate the use of quantum interference for characterizing the high-dimensional entanglement nature by avoiding some stringent conditions.
