Quantum sensing, along with quantum communications and computing, is commonly considered as the most important application of optics. Among quantum-sensing experiments, schemes based on squeezed states light are popular choices due to their natural quadrature components. Since first experimental demonstration quantum-squeezing-enhanced phase measurement beyond shot-noise limit in 1987, quantum-squeezing techniques toward practical sensing tracking have been extensively investigated. In this...
Efficient catalysts are highly desirable for the selective electrochemical CO2 reduction reaction (CO2RR). Ni single-atom known as promising CO2RR catalysts, while NPs expected to catalyze competing HER. In this work, we have modified by encapsulating them into porous Ni-N-C nanosheets (Ni@Ni-N-C), boost synergy between and dispersed Ni-N species towards CO2RR. The CO faradaic efficiency (FECO) reached 96.4% at -0.9 V retained over 90% in a wide potential window. More importantly, FECO...
We construct an experimental measurement system for rotation vibration signal detection using the orbital angular momentum (OAM) of light in a Sagnac interferometer. Inputting beams with different OAM, we demonstrate that measured and signal-to-noise ratio can be increased by OAM mode index l. In addition, interferometer further improve suppress environmental noises. Such has potential applications high-precision sensing monitoring vibrations.
Four organic amine-based solvents were discovered which enable direct exfoliation of graphite to produce high-quality and oxygen-free graphene nanosheets. These outperform previously used additives such as N-methyl-pyrrolidone surfactants in terms their dispersing capacity. The resulting dispersions allow the facile fabrication zeolitic imidazolate framework (ZIF)–graphene nanocomposites with remarkable CO2 storage capability.
We propose and experimentally demonstrate a quantum-enhanced fiber Mach-Zehnder interferometer for low-frequency phase measurement beyond the shot-noise limit using high-frequency squeezing technique. The local oscillator field is amplitude-modulated in MHz range then demodulated to avoid technical noise that occurs at low frequencies. After of frequency tens kHz, an improvement ∼2 dB relative level achieved. Additionally, amplitude modulation depth has no significant effect on when deployed...
Balanced homodyne detection, which offers advantages that include low noise and strong anti-interference capabilities, is commonly used as a detection method in quantum metrology.

The device exhibits interference efficiency 99% common-mode rejection ratio 40 dB, thus enabling dynamic monitoring...

This mechanism inherently related to spontaneous down-conversion currently constitutes building block for entangled photon pair generation, which has been exploited modern quantum technologies ranging from computing communications and...
In the past decades, quantum plasmonics has become an active area due to its potential applications in on-chip plasmonic devices for information processing. However, fundamental physical process, i.e., how a state of light evolves photon-plasmon conversion not been described by detailed microscopic model.

Abstract Optical phase tracking is an important technique for use in high-precision measurement applications, including optical frequency metrology and ground- or space-based gravitational wave observation, coherent communications. When measuring fast-varying real-time signals, the response time limitations of system’s phase-locked loop cause best operating point to be mismatched, then becomes nonlinear. To make these measurements possible, this work proposes a delay that theoretically...
