Summary: Beam-splitting photon number resolved (PNR) detection can generate antibunching light by subtracting odd photons from superbunching squeezed vacuum light. This technique can be used for engineering various nonclassical light by performing PNR measurements on squeezed vacuum light. The key is to use beam-splitting PNR detection to subtract odd photons and achieve the desired photon distribution.

Summary: In this paper, the higher and lower-order nonclassicalities of photon-added then-subtracted and photon-subtracted-then-added thermal and even coherent states are studied. Different criteria are used to witness the nonclassical feature, and it is found that the considered states are highly nonclassical. The non-Gaussian photon-addition-then-subtraction operation is also preferred over the photon-subtraction-then-addition for developing nonclassicality.

Summary: Superconducting nanowire single-photon detectors (SNSPDs) with high system detection efficiency (SDE), low dark counts, and fast recovery time have enabled the realization of various quantum optics technologies. This article presents an SNSPD array composed of 14 independent pixels, achieving an SDE of 90% in the telecommunications band. By reading each pixel of the array independently, the detection of telecommunication photons at 1.5 GHz with 45% absolute SDE is demonstrated. The dynamic photon-number resolution of the array is exploited for accurate state reconstruction of a wide range of light inputs, including long-duration light pulses obtained with cavity-based sources. Two-photon and three-photon fidelities of 74% and 57% are shown, respectively, representing state-of-the-art results for fiber-coupled SNSPDs.

Summary: Heliorhodopsins (HeRs) are a new category of rhodopsins, which exist as dimers and have an inverted topology. This study investigated the conformational changes of HeRs using the transient grating (TG) and circular dichroism (CD) methods. The results showed that there were no significant conformation changes on the protein's surface during the early steps of the reaction, but a decrease in diffusion coefficient (D) was observed after the formation of the O intermediate. The contribution of the ICL1 helix in the conformational changes was examined. The study suggests that the hydrophilic residues in the ICL1 helix undergo structural changes during the process.

Summary: We demonstrate quantum random number generation using a photon-number detection scheme and silicon photomultiplier technology. Our method accurately resolves photon numbers using detector response signals, which are then digitized into a stream of 4-bit sequences. The generated random bits pass statistical randomness validation and this scheme can be implemented using inexpensive components, with the potential for miniaturization into a plug-and-play portable cryptographic device.

Summary: In this study, a new type of self-pulsation phenomenon in a microcavity Brillouin laser is demonstrated, which is generated by the interplay between Brillouin lasing and thermo-optic effect. The self-pulsation behaviors are observed in both forward input pump and backward Brillouin lasing emission, with excellent agreement between numerical simulations and experimental results achieved through the development of a coupled-mode theory.

Summary: This study investigates the recycling of nonlocal resources in a quantum network and demonstrates it experimentally. It shows that in a three-branch star network, outer parties can achieve sufficient entanglement with a central node through unsharp measurements, allowing the same operation to be performed by three secondary parties. This experiment combines the research programs of recycling quantum resources with that of Bell nonlocality in networks.
