Openness and collaboration in scientific research are attracting increasing attention from scholars practitioners alike. However, a common understanding of these phenomena is hindered by disciplinary boundaries disconnected streams. We link dispersed knowledge on Open Innovation, Science, related concepts such as Responsible Research Innovation proposing unifying Science (OIS) Framework. This framework captures the antecedents, contingencies, consequences open collaborative practices along...
We demonstrate spin squeezing in a room temperature ensemble of $\ensuremath{\approx}{10}^{12}$ cesium atoms using their internal structure, where the necessary entanglement is created between nuclear and electronic spins each individual atom. This state provides improvement measurement sensitivity beyond standard quantum limit for memory experiments applications metrology thus complementary alternative to obtained via interatom entanglement. Squeezing collective verified by tomography.

In addition, we events for game development: hackathons, jams, semester projects. Furthermore, discuss Technologies Education Everyone (QUTE4E) pilot...
Abstract In this article, we investigate a growing trend in the worldwide Quantum Technology (QT) education landscape, that of development master’s programs, intended to provide graduates with knowledge and skills take job quantum industry, while serving much shorter timeline than doctoral degree. Through global survey, identified 86 substantial growth since 2021. Over time have become increasingly interdisciplinary, organised by multiple faculties or through joint degree offer more hands-on...
We present the production of dual-species Bose-Einstein condensates (BECs) $^{39}\mathrm{K}$ and $^{87}\mathrm{Rb}$. Preparation both species in $\left|F=1,{m}_{F}=\ensuremath{-}1\right\ensuremath{\rangle}$ state enabled us to exploit a total three Feshbach resonances, which allows for simultaneous tuning intraspecies $^{39}\mathrm{K}\text{\ensuremath{-}}^{87}\mathrm{Rb}$ interspecies scattering length. Thus were produced by sympathetic cooling with A dark spontaneous force optical trap was...

We discuss quantum optimal control of Bose-Einstein condensates trapped in magnetic microtraps. The objective is to transfer a condensate from the ground state first-excited state. This type problem typically solved using derivative-based methods high-dimensional space such as gradient-ascent pulse engineering (GRAPE) and Krotov's method or derivative-free reduced Nelder-Mead with chopped random basis (CRAB). how these can be combined gradient optimization parametrization (GROUP) including...

We propose an efficient strategy to find optimal control functions for state-to-state quantum problems. Our procedure first chooses input state trajectory, that can realize the desired transformation by adiabatic variation of system Hamiltonian. The shortcut-to-adiabaticity (STA) formalism then provides a Hamiltonian realizes reference trajectory exactly but on finite time scale. As final is achieved with certainty, we define cost functional incorporates resource requirements and...
We prepare number stabilized ultracold atom clouds through the real-time analysis of nondestructive images and application feedback. In our experiments, N∼10^{6} is determined by high precision Faraday imaging with uncertainty ΔN below shot noise level, i.e., ΔN<sqrt[N]. Based on this measurement, feedback applied to reduce a user-defined target, whereupon second series probes cloud. By method, we show that in can be prepared level.
Ultracold atomic gases have recently become a driving force in few-body physics due to the observation of Efimov effect. While initially observed equal mass systems, one expects even richer heteronuclear case. In previous experiments with ultracold mixtures potassium and rubidium, an unexpected nonuniversal behavior resonances was observed. contrast, we measure scattering length dependent three-body recombination coefficient $^{39}\mathrm{K}\text{\ensuremath{-}}^{87}\mathrm{Rb}$...
Fluctuations are a key property of both classical and quantum systems. While the fluctuations well understood for many systems at zero temperature, case an interacting system finite temperature still poses numerous challenges. Despite intense theoretical investigations atom number in Bose-Einstein condensates (BECs), their amplitude experimentally relevant is poorly understood. Moreover, technical limitations have prevented experimental observation to date. Here we report first these...
Citizen science methodologies have over the past decade been applied with great success to help solve highly complex numerical challenges. Here, we take early steps in quantum physics arena by introducing a citizen game, Quantum Moves 2, and compare performance of different optimization methods across three optimal control problems varying difficulty. Inside players can apply gradient-based algorithm (running locally on their device) optimize solutions find that these results perform roughly...
