TL;DR: In this article, a superconducting qubit was used to detect the presence of a single magnon, a magnetic excitation associated with electron spins, and the same technology can detect a steady state population of magnons with a greater sensitivity than past methods.
Abstract: E arlier this year, a team of researchers at the University of Tokyo showed that they could use a superconducting qubit to detect the presence of a single magnon—a magnetic excitation associated with electron spins. Now, this group, led by SamWolski, has demonstrated that the same technology can detect a steady-state population of magnons with a greater sensitivity than past methods [1]. The development is an example of how quantum technologies, such as qubits, can lead to improvements in sensing and other applications.

TL;DR: In this paper, the mechanism that makes some oil droplets change shape from spheres to icosahedrons to flattened plates was uncovered, and it was shown that some droplets can change shape in a single pass.

TL;DR: Leidenfrost drops suspended above a hot surface by a thin layer of vapor emit periodic sounds in a similar way to pipe organs as discussed by the authors, similar to the pipe organs of pipe organs.

TL;DR: Spatially overlapped multi-object detection is experimentally demonstrated in single-photon time-gated ToF for the first time and extended dynamic range is demonstrated in dual exposure operation mode.
Abstract: We present the first 1Mpixel SPAD camera ever reported. The camera features 3.8ns time gating and 24kfps frame rate; it was fabricated in 180nm CIS technology. Two pixels have been designed with a pitch of 9.4$\mu$m in 7T and 5.75T configurations, respectively, achieving a maximum fill factor of 13.4%. The maximum PDP is 27%, median DCR 2.0cps, variation in gating length 120ps, position skew 410ps, and rise/fall time <550ps, all FWHM at 3.3V of excess bias. The sensor was used to capture 2D/3D scenes over 2m with an LSB of 5.4mm and a precision better than 7.8mm. Extended dynamic range is demonstrated in dual exposure operation mode. Spatially overlapped multi-object detection is experimentally demonstrated in single-photon time-gated ToF for the first time.

TL;DR: In this paper, the magnetostatic mode of a ferrimagnetic crystal is coupled to a superconducting qubit for the detection of magnons using Ramsey interferometry with a sensitivity on the order of 10 − 3magnons/sqrt[Hz].
Abstract: Hybrid quantum devices expand the tools and techniques available for quantum sensing in various fields. Here, we experimentally demonstrate quantum sensing of a steady-state magnon population in a magnetostatic mode of a ferrimagnetic crystal. Dispersively coupling the magnetostatic mode to a superconducting qubit allows for the detection of magnons using Ramsey interferometry with a sensitivity on the order of 10^{-3} magnons/sqrt[Hz]. The protocol is based on dissipation as dephasing via fluctuations in the magnetostatic mode reduces the qubit coherence proportionally to the number of magnons.

TL;DR: In this paper, it has been shown that the rapid legislative or illegal introduction of quotas for minorities instead of increasing their scientific level and well-being can only limit the recruiting of talented people of any gender or race into science and will result in the decline of the world science as a whole.
Abstract: Some aspects of the radical change of value orientations in modern western science are considered. Influenced by leftist ideology and under the slogans of abstract justice, the leadership of European and North American institutions is trying to expand the presence of new members in the scientific and educational spheres on the quota basis, taking into account racial and gender rather than meritocratic characteristics (high-quality basic and university education level, persistence to obtain new knowledge, developed mental abilities in this area). It has been shown that the rapid legislative or illegal introduction of quotas for minorities instead of increasing their scientific level and well-being can only limit the recruiting of talented people of any gender or race into science and will result in the decline of the world science as a whole.

TL;DR: In this article, the authors give some brief remarks on vibrations found in liquids floating over highly heated surfaces for the overlooked period from the late 1700s up to the work of Holter and Glasscock in 1952.
Abstract: Leidenfrost drops often exhibit symmetric shape-oscillations when placed onto curved substrates. We give some brief remarks on vibrations found in liquids floating over highly heated surfaces for the overlooked period from the late 1700s up to the work of Holter and Glasscock in 1952 [J. Acoust. Soc. Am. 26, 253 (1952)]; the latter pair were incorrectly credited as the first to observe such behavior in Leidenfrost drops.
