Summary: The proposed Heisenberg-limited quantum interferometer uses twin optical beams with indistinguishably subtracted photons to achieve Heisenberg-limited performance and direct fringe reading. A feasible experimental realization using photon-number correlated sources, such as nondegenerate parametric down-conversion, was proposed for performance analysis in the presence of loss and detector inefficiency.

Summary: This paper proposes a frequency-diverse multi-mode (FDMM) OAM modulator with approximately equal divergence angle. The modulator consists of an OAM modulation metasurface and a spatial filter (SF) with narrow passband. The OAM modulation metasurface is designed based on multiple ring-like regions with different radii, generating different modes of OAM beams at different frequencies simultaneously. The SF is proposed to reduce interferences between different modes of OAM beams. The FDMM OAM modulator can generate six modes of OAM beams at different frequencies and can be used for target reconstruction with improved imaging performance.

Summary: In the past few decades, optical magnetometry has made remarkable progress in sensitivity, but is limited by spin projection noise, photon shot noise, and magnetic noise. In this study, a quantum magnetic gradiometer with sub-shot-noise sensitivity is demonstrated using entangled twin beams, showing great potential for developing sensitive magnetometry in noisy environments.

Summary: In this study, a monolithically integrated triaxial high-performance accelerometer with pure axial stress piezoresistive beams was designed and tested. By controlling synchronous displacements at both piezoresistive beam ends, the pure axial stress states of the piezoresistive beams could be easily achieved without tedious calculations. The approach simplifies the design process and provides high-performance piezoresistive accelerometers.

Summary: The combustion behavior of five full boiling range RON98 gasoline blends was evaluated for multi-mode operation in a GDI and the CFR octane rating engine. Despite having the same RON and octane sensitivity, different knock limited SI and HCCI combustion behavior was observed for the test fuels. It was found that knock-limited combustion phasing in the GDI engine did not align well with the RON.

Summary: Light-field microscopy is a promising solution for microscopic volumetric imaging, but suffers from spatial resolution loss. In this article, a new scheme called Correlation Light-field Microscopy (CLM) is introduced, which exploits the correlation between two light beams to achieve diffraction-limited volumetric imaging. Experimental results show that CLM is capable of recovering information from out-of-focus planes and improving depth of field compared to conventional microscopy.

Summary: This paper introduces a novel adaptive multibeam receiver that can separate and simultaneously detect multiple beams sharing the same wavelength and polarization in the optical domain. By using a programmable integrated photonic processor and a two-dimensional array of optical antennas, the separation of beam pairs with different directions and overlapping spatial modes is achieved.

Summary: The THz electro-optical sampling technique using single-photon detectors and squeezed vacuum field as the optical probe has been successfully demonstrated in experiments. The sensitivity of the field measurement is limited by the statistical properties of the probe state, which can be improved by using phase-locked single-photon detectors.
