Summary: A new generation of neutrino experiments is testing the anomalous excess of electronlike events observed in MiniBooNE. This is of huge importance for particle physics, astrophysics, and cosmology. The recent results from MicroBooNE are promising, but they do not fully explore the parameter space of sterile neutrino models hinted at by MiniBooNE and other data, nor do they probe the MiniBooNE excess in a model-independent way.

Summary: The excess of electron-like events measured by MiniBooNE challenges our understanding of neutrinos and their interactions, with ongoing efforts to resolve the issue. Experimental backgrounds, neutrino interactions with matter, and the difficulties reconciling findings with global oscillation analysis are key areas of study. Proposed solutions to the puzzle involve unconventional neutrino-interaction mechanisms.

Summary: By optimizing the efficiency of a quantum-dot-based micropillar single-photon source, we identified periodic enhancement in background emission with the diameter, which can reduce the efficiency by around 20%. Choosing a diameter away from these peaks can avoid this reduction. Additionally, discrepancy between experimentally estimated Purcell factor and true Purcell factor was analyzed.

Summary: The optimization of superconducting materials and the improvement of nanofabrication process have enabled the demonstration of large-area superconducting nanowire single-photon detectors (SNSPDs) with unity internal detection efficiency (IDE) in the mid-infrared (mid-IR) band. The approach yields large-area meanders with minimal line-width roughness and reduced impact from constrictions, paving the way for high-efficiency SNSPDs in the mid-IR band with potential impacts on astronomy, imaging, and physical chemistry.

Summary: The electric-field distribution in a single mode of a lambda/4 superconducting coplanar waveguide (CPW) microwave resonator has been probed using beams of helium Rydberg atoms. The coherence times of the atom-resonator-field interaction and the atomic superposition states were determined, and residual uncanceled dc electric fields were measured.

Summary: Single-photon sources based on single emitters are highly interesting for various applications and have been realized using different materials. Common factors related to relaxation times of internal states indirectly affect the photon number stability. GaN emitters demonstrate higher stability due to faster relaxation times compared to hBN emitters, but hBN emitters have higher photon generation rates. Repeatable radiant flux measurements of a bright hBN single-photon emitter for a wide range of fluxes have been demonstrated.

Summary: Color centers in silicon carbide are promising emitters for single-photon emitting diodes (SPEDs), but their spectral emission properties at room temperature are not ideal. By decreasing the operating temperature, spectral properties can be improved, although the efficiency of electrical excitation decreases due to a reduction in free charge carrier densities. This research explores the temperature characteristics of SPEDs based on color centers in 4H-SiC, demonstrating the potential for high brightness and improved spectral properties at lower temperatures through hole superinjection in homojunction p-i-n diodes.

Summary: A high-speed airborne single-photon counting LiDAR operating at 1550 nm was developed, achieving a point cloud rate of 1.4 x 106 points per second with a 1-MHz repetition rate pulsed laser. The LiDAR utilized a quasi-continuous Geigermode single-photon detector, and a processing algorithm based on the difference of signal and noise in density distribution was proposed to distill the three-dimensional information of the targets, demonstrating its suitability for terrain mapping and three-dimensional city modeling.

Summary: Unsupervised landmark learning is a task to learn semantic keypoint-like representations without using expensive input keypoint annotations. This paper proposes to factorize the reconstruction task into foreground and background reconstructions in an unsupervised way, allowing the model to condition the foreground reconstruction on unsupervised landmarks, which improves the rendered background quality while ensuring the reconstruction of the foreground object of interest.

Summary: The nitrogen-vacancy (NV) center in diamond is crucial for achieving high-fidelity single-shot readout of qubits, with a new spin-to-charge conversion method introduced to suppress spin-flip errors. This technique shows potential for exceeding fault-tolerant thresholds and may have applications in integrated optoelectronic devices.

Summary: The study focuses on understanding photon backgrounds in the MiniBooNE detector, which cannot distinguish between electron-like signals and photon backgrounds. Two sources of backgrounds are explored: the 2p2h gamma process which can explain a significant portion of the excess events observed, and the mis-identification of photons from pi(0) -> gamma gamma decay as an electron-like shower. The results suggest a reduction in the significance of the MiniBooNE excess by 0.4 sigma.

Summary: In 1927, Einstein conducted a thought experiment at the Solvay conference to demonstrate the incompleteness of quantum mechanics. By using the Stern-Gerlach experiment, he showed that single-particle entanglement can produce nonlocal effects, opening up the possibility of implementing truly nonlocal tasks.

Summary: Neutrino oscillation experiments aim to establish charge-parity violation by measuring the rate of neutrino appearance and disappearance in a beam, but are influenced by theoretical constraints and corrections. Using a factorization theorem helps minimize uncertainties in predicting neutrino cross-section ratios.

Summary: The Mu2e and COMET collaborations are searching for nucleus-catalyzed muon conversion to positrons as a signal of lepton number violation, with radiative muon capture as a key background. This work describes how the near end point internal positron spectrum can be related to the real photon spectrum from the same nucleus.
