Nature Phys. 9, 341–344 (2013).The experimental set-up is largely based on refs 25, 26. Ultracold 4He ∗ is magnetically trapped and evaporatively cooled 27 to just below the Bose–Einstein condensate transition temperature ( ∼1 μK). Approximately 10 4 atoms are transferred into a vertical optical dipole trap by ramping up the intensity of a far red-detuned focused laser beam in the direction of gravity over 200 ms. The magnetic trap is switched off and the only magnetic field present is generated by our magnetic field stabilization ‘nullerometer’ 28, which provides a bias magnetic field ∼1 Gauss. Then, the dipole trap is ramped down over 100 ms, resulting in a trap with harmonic frequencies of ( ω x, ω y, ω z)/2π = (1800,1800,12) Hz. The trap depth (equivalent to a temperature of a few nanokelvin) is then held at this point for two seconds, which allows the majority of the thermal atoms to exit thetrap. Single-atom source.

The ever-increasing demand for family-friendly activities and toys continues into 2023 and Character Options is meeting that demand with fresh new developments within its Stay Active collection. Stay Active is the family-inclusive range of toys that can be played with inside and outside, while having great active fun. And with the range now having developed into a whole division within the portfolio, having benefited from the firm’s significant investment into the marketing and influencer programme in 2022, buyers and retailers can expect this raft of activity to continue into the year ahead. The final quarter saw Olympian Gold Medallist and Celebrity MasterChef champion Greg Rutherford among other celebs and high-profile influencers, including Sophie Ellis-Bextor and ‘H’ from Steps, take on the ultimate fast, fun musical jump challenge fitness game, Jump It Wipe Out, catapulting it onto Christmas wish lists and guaranteeing its success at launch. And now the company is promising an even bigger programme of activity for the growing Stay Active range. Recent advances in the trapping and cooling of atoms has led to the ability to readily observe wavelike phenomena with particles that have mass, such as the interference between two Bose–Einstein condensates 13. However, progress towards demonstrating Wheeler’s experiment with massive particles, such as a delayed-choice Stern–Gerlach interferometer with metastable hydrogen 14 or a spin interferometer with neutrons 15, have been limited. Importantly, these experiments used beams containing more than one particle in the apparatus at any one time, rendering a meaningful test of Wheeler’s ideas impossible, at least at the quantum level. Nonetheless, they demonstrate an advantage of using massive particles over photons, the relatively slow velocity (compared to light) of the atoms through the interferometer allows an increased time for making the delayedchoice.

Real magic reappears when you cast your spell within the Smyths Magic Mixies Magical Crystal Ball and create a horoscope-reading pet. Use this feature-rich mystical sprinkling Crystal Ball from the makers of the Magic Mixie Magic Pot to hone your spell-casting skills and perform Real Magic. Build your own own fortune-telling Magic Mixie by casting the Creation Spell on your dynamic light-up magic wand. Be astonished at the remarkable way your Crystal Ball reacts to wand motions. We use an ultracold (<1 nK) source of single atoms 16 to implement Wheeler’s idea: that the behaviour of the atom can indeed be induced by our choice of measurement. Our experimental set-up closely mirrors that of the Mach–Zehnder scheme originally proposed by Wheeler ( Fig.1b), where essentially the roles of light and matter have been reversed. Atoms are released from an optical dipole trap (see Methods) and fall under gravity towards a delay-line detector (DLD) capable of imaging single He ∗ atoms with three-dimensionalinformation.

For each phase of the Creation Spell, you must perfect the corresponding wand action and magic word. The Crystal Ball must first be awakened before you can give your Magic Mixie its voice and colour. Then, after pronouncing the magic phrase "MAGICUS MIXUS," educate your Mixie how to tell stories to bring it to life. Once the mist has dissipated, your Magic Mixie will magically materialise. As magic happens within, observe how bright noises and lights change and move. Here, we report the first realization of Wheelers famous delayed-choice gedanken experiment with single massive particles. The only successful demonstration of Wheeler’s ideas so far has been achieved with single photons 2. Here we use atoms, which is an important distinction, since atoms have many internal degrees of freedom. This allows coupling to the external environment through, for example, the atom’s sensitivity to magnetic and electric fields. Moreover, an atom has significant mass, which allows strong coupling to gravitational fields. These interactions of the atom with its environment are required for the appearance of decoherence; thus, in this sense an atom can be thought of as a more classical particle than a photon. As such, our experiment tests Wheeler’s ideas in a regime in which it has never beentested.
