Détecter une seule particule de lumière est un défi, mais détecter un photon micro-ondes l’est encore plus: ils sont 100'000 fois plus faible que les photons optiques.
Des scientifiques du Laboratoire des circuits quantiques hybrides ont développé un mini détecteur capable de relever ce défi avec une efficacité pouvant atteindre 70%, en convertissant les photons micro-ondes entrants en un courant électrique faible, mais mesurable.

#MIT- #Experiment bestätigt #Quantenmechanik
#Doppelspaltexperiment auf #atomarer Ebene belegt endgültig, dass die #Interpretation der #Quantenmechanik von #NielsBohr korrekt ist.
Damit sollte abschließend geprüft werden, ob das #Photon sich sowohl als Teilchen als auch als Welle verhält, wie #AlbertEinstein es vorhergesagt hatte. #NielsBohr hingegen bestritt das und sagte voraus, dass nur eine der beiden Eigenschaften beobachtet werden könne.

Interesting, i am still in the stage of evaluating this concept/idea in my head but definitely worth reading.

Weird New #Quantum #Experiment Sounds Suspiciously Like Time Travel
…"A negative time delay may seem #paradoxical, but what it means is that if you built a #quantum #clock to measure how much time atoms are spending in the excited state, the clock hand would, under certain circumstances, move backward rather than forward"… Josiah Sinclair from the #University of #Toronto. [Movement known as #retrograde.]

Evidence of ‘Negative Time’ Found in #QuantumPhysics ExperimentPhysicists showed that #photons can seem to exit a material before entering it, revealing observational evidence of #negativetime.
…"by the team’s experiments, these values can encompass instances when an individual #photon’s transit time is instantaneous—or, bizarrely, when it concludes before the #atomic excitation has ceased, which gives a negative value"…

A team from the Institute of Applied Physics at #UniJena has developed a microscopically small crystal that can be used to generate entangled #photon pairs. This could enable #QuantumCommunication in mobile devices.

Natürlich nimmt man von einer Reise viele Erinnerungen mit, oft in Form von Urlaubsfotos. Wir versorgen die Lernenden an der #Karl-von-Ibell-Schule mit den entsprechenden Hintergründen. Palmen, Meer, Sehnsuchtsorte. Auf zum 4. Tag unserer Südseereise

Unsere erste Reise in die Südsee hat gestern begonnen. Die Karl-von-Ibell-Schule ist mit uns gemeinsam unterwegs, um Sehnsuchtsorte zu erkunden und Neues zu entdecken. Dabei nutzen wir Medien unterschiedlichster Art. Das Kollegium der KvI hat sich schon im Vorfeld auf die Reise eingestimmt und auf der Schulwebsite ein Video veröffentlicht.

Das wirkt jetzt vielleicht etwas übertrieben, aber so sieht es aus, wenn wir uns auf eine Projektwoche in einer Grundschule vorbereiten. 😉

2023’s Best #MidDrive #eBike Kit - Better than #Bafang #BBSHD?
First look at the new #cycmotor #photon #middriveebike conversion kit. This is the latest edition to #cyc’ s x1 pro gen 3 & x1 stealth gen 3 models. The new cyc photon is much closer in design to the bafang bbshd mid drive motor. The power of the photon is less that of the bafang bbshd but it delivers other benefits including a #torquesensor bottom bracket.

Also cleaned out my container of Micro-Controllers, these are controllers, that I simply don't use any more.
I pretty much spend most of my time working with #ESP32 any more - and these just seem like they are taking up room I could be using for more #ESP32 boards LOL.I'm not getting rid of them, just putting them in a different box, that doesn't stay near the work bench.

A #single #photon is enough to catalyze #photosynthesis in bacteria, and likely in plants as well.
Researchers analyzed the light-harvesting 2 (LH2) complex of the purple bacterium Rhodobacter sphaeroides. This is composed of a smaller ring that contain nine bacterial #chlorophyll molecules and a larger ring made of 18 of these molecules.
To see these molecules absorb photons, scientists depended on quantum mechanical #entanglement.
Essentially, two or more particles such as photons that are linked or "entangled" can influence each other no matter how far apart they are. Analyzing one entangled photon can therefore reveal what is happening with its partner.
The scientists generated entangled pairs of photons. They sent one photon from each pair directly to a highly sensitive detector. This "herald" photon helped confirm its partner was on its way to illuminate LH2.
Absorbing this second photon led the photosynthetic complex to fluoresce, emitting a weak pulse of light that another detector helped sense.
By analyzing more than 17.7 billion herald photon detections and 1.6 million fluorescence detections, the researchers confirmed "a #single #photon is enough to initiate #photosynthesis," Fleming says.
Since all photosynthetic life on Earth use similar chemical reactions, the scientists are confident these findings in bacteria apply to photosynthesis in plants and algae.
"This is an important milestone," Gregory Scholes, chair of chemistry at Princeton University, who did not take part in this research, tells Inverse. These new findings suggest the information from laser experiments "does represent what happens under natural conditions," he notes

"We show that optical bias fields injected into multistable #optical systems enable a controllable source of #quantum #randomness, and we demonstrated this concept in an optical parametric oscillator (OPO). By injecting bias pulses with less than one #photon on average, we controlled the probabilities of the two possible OPO output states."

Dank Röntgenfluoreszenz (#XRF) kann durch eine spektrale Messung die elementare Aufbau von Materie analysiert werden.
Ähnlich zur optischen #Fluoreszenz wird ein #Atom angeregt: Ein #Photon mit Energie oberhalb einer Absorptionsschale kann vom Atom absorbiert werden, woraufhin ein #Elektron die Hülle verlässt (Ionisation), oder auf eine energetisch höhere Bahn gebracht wird. -

"Here, we realize a Fermi gas featuring both strong, tunable contact interactions and #photon-mediated, spatially structured long-range interactions in a transversely driven high-finesse #optical cavity. Above a critical long-range interaction strength, density #wave order is stabilized in the system, which we identify via its #superradiant light-#scattering properties."
