Summary: The dual-comb technique is a powerful tool in industrial inspection and scientific research, capable of achieving high-resolution and broadband spectral measurements. We propose an absolute angular-position measurement method based on dual-comb spectroscopy, which achieves a precision of 0.12 arcsec in a dynamic range of approximately 6660 arcsec. Compared with a commercial auto-collimator, the comparison residuals are kept within +/- 0.3 arcsec for angles over 1000 arcsec.

Summary: Photoacoustic spectroscopy (PAS) using two optical combs offers broad bandwidths, high resolutions, fast acquisition speeds, and wavelength-independent detection. However, sensitivity and specificity are limited. In this study, we demonstrate comb-enabled PAS with enhanced sensitivity and nonlinear spectral hole-burning defined resolution, enabling trace detection and Doppler-free gas sensing.

Summary: This paper proposes a microwave photonics instantaneous frequency measurement scheme with 14 channels based on an optical frequency comb (OFC). The scheme generates a 14-line flat OFC by cascading a dual-parallel Mach-Zehnder modulator (DPMZM) with a Mach-Zehnder modulator (MZM). By utilizing various optical devices and an optical power detector array, the scheme can measure microwave signals with multiple-frequency components. It offers high measurement accuracy and reconfigurability.

Summary: A disambiguation method for dual-comb sampling frequency measurement is proposed and experimentally demonstrated. By exploiting the phase relationship between the intermediate frequencies and the first harmonics of the two sampling rates, most of the ambiguous frequencies can be distinguished. The nonideal phase response of the devices is found to reduce the performance, especially in high frequencies. An improved method that observes and uses the variations of the phases to solve the ambiguity is given to overcome this issue.

Summary: In this paper, a traveling quantum anonymous voting (TQAV) protocol is proposed, which utilizes a monolithic microresonator with cascaded four-wave mixing (FWM) to prepare continuous-variable frequency entanglement sources. Multi-pair EPR entangled states and five-partite entangled states generated from the degenerate and nondegenerate FWM process are used as signal sources to characterize different candidates. Voters can vote for their preferred candidates by performing displacement operations on the received modes, and the ballot agency can judge the result according to the measurements. The entanglement property of the quantum state is utilized to ensure voter privacy, and the security of the protocol is guaranteed by the security mechanism of continuous-variable quantum key distribution. The results provide a reference for the application of optical frequency comb in multiparty quantum communication.

Summary: We present an architecture for wavelength-division-multiplexed coherent data center links using resonator-enhanced electro-optic frequency comb generators. The phase noise in each frequency comb is determined by the optical phase noise of the seed laser and the phase noise of the microwave oscillator. We propose an analog coherent receiver that performs carrier recovery on all wavelength channels using only two phase-locked loops.

Summary: A narrow-linewidth optical frequency comb is developed for frequency stabilization in order to couple telecommunication wavelength photons with quantum memories. Phase-locking to an iodine-stabilized Nd:YAG laser is used to achieve frequency stabilization in the developed optical frequency comb. The control laser of a Pr3+:Y2SiO5 (Pr:YSO) quantum memory is then phase-locked to the optical frequency comb, allowing for sufficient linewidth and frequency stability for multimode storage in the Pr:YSO quantum memory.

Summary: A multi-channel silicon photonic transmitter based on WDM and MDM was demonstrated, utilizing a silicon nitride Kerr frequency comb as the light source and silicon electro-optic modulators for optical modulation. By employing three wavelengths and two modes, the optical transmission capacity was increased to 150 Gb/s. The integration of WDM and MDM components with a compact optical comb source opens new avenues for high-capacity multi-dimensional optical transmission in the future.

Summary: We report the generation of quantum correlated triple beams via cascaded four-wave mixing in single hot atomic vapor. The experiment demonstrates strong quantum correlation among the three beams, with a maximum intensity-difference squeezing of -7.8 +/- 0.3 dB. The study also reveals quantum correlation between two idler beams and the ability of the injecting probe field to manipulate the gain and intensity-difference squeezing of the output three-mode light. Furthermore, the Autler-Townes splitting of gain peaks leads to the evolution of measured two- and three-mode intensity-difference squeezing from single-mode to multi-mode in the frequency domain, providing a potential resource for multi-mode entanglement and quantum networks.

Summary: This paper investigates the characteristics of asymmetric microcavities supporting Whispering-gallery modes (WGMs) and their applications in on-chip optical information processing. By establishing asymmetric microcavities on topologically curved surfaces, the cavity mode features are completely reconstructed by geodesic light trajectories. The photon-lifetime engineering mediated by curvature enhances the quality factors of periodic island modes. At large space curvatures, high-Q periodic modes protected by stable island-like light trajectories replace the role of the WGMs.

Summary: This study reports the formation mechanism and non-Hermitian properties of optical skyrmions formed by photonic spin-orbit coupling. By introducing circularly polarized gain and loss, as well as spatially inhomogeneous pumping, the spin textures of skyrmions can be controlled, and skyrmion lasers can be achieved. These findings provide a new approach for the non-Hermitian control of photonic spin in confined systems.

Summary: We use complex network theory to study a class of photonic continuous variable quantum states that have both multipartite entanglement and non-Gaussian statistics. These states are created from an initial imprinted cluster state via Gaussian entangling operations according to a complex network structure, and then non-Gaussian statistics are generated through multiple photon subtraction operations on a single node. We investigate the emergent network of photon-number correlations through complex network measures, and show that the structure of the imprinted network greatly influences the emergent structure.

Summary: We analytically determine the quantum Cramer-Rao bound for estimating the separation between two point sources in arbitrary Gaussian states. Our analysis is applicable for arbitrary source brightness and examines how different resources affect the ultimate resolution limit with the number of emitted photons. In practical scenarios, coherent states of the sources achieve quantum optimal resolution.

Summary: This paper analyzes the problem of resolving two mutually coherent point sources with arbitrary quantum statistics, mutual phase, and relative and absolute intensity. A sensitivity measure based on the method of moments is used, and direct imaging is compared with spatial-mode demultiplexing (SPADE), demonstrating the advantage of the latter. The paper shows that the moment-based sensitivity of SPADE saturates the quantum Fisher information for all known cases, even for non-Gaussian states of the sources.
