Innsbruck Scientists led by Peter Zoller have developed a new tool for measuring #entanglement in many-body systems and demonstrated it in experiments.

The method enables the study of previously inaccessible physical phenomena and could contribute to a better understanding of quantum materials.

The work has now been published in @Nature

The temperature profiles obtained by the researchers show that particles that interact strongly with the environment are “hot” (red) and those that interact little are “cold” (blue). Entanglement is therefore large where the interaction between particles is strong.

La nostra ricerca teorica sulla creazione di #entanglement tra atomi in cavità ottica tramite misure continue mostra una buona scalabilità dello spin squeezing.

A. Caprotti, ora dottorando presso l'Univ. di Vienna, ha svolto un ruolo cruciale nelle simulazioni #quantum utilizzando #QuTiP.

Motivati dallo sviluppo dell'orologio ottico allo Sr in INRiM da M. G. Tarallo e M. Barbiero, abbiamo beneficiato dall'esperienza di M. G. Genoni sulla dinamica condizionale.

Our theoretical study on #entanglement among atoms in an optical cavity, measuring transmitted light, shows favorable scaling of spin squeezing, even in the absence of continuous feedback.

A. Caprotti, now a PhD at the Univ. of Vienna, played a pivotal role in #quantum simulations using #QuTiP.

Motivated by M. G. Tarallo and M. Barbiero, developing the Strontium optical clock at INRiM, we benefited from M. G. Genoni's expertise on conditional dynamics.

I think I am going to try to make an actual experimental device THAT JOHN STEWART BELL COULD HAVE MADE though of course he was at CERN and could have programmed a computer and so experimented more straightforwardly.

This device will disprove the stupid #quantum #entanglement #non-locality #irreducibility claptrap superstitious pseudoscience cult doctrine.

It will be a sort of quarter-circle pan, with an adjustable radial baffle, into which go little colored beads.

That is it.

E se vi dicessi che la scienza sta flirtando con l'idea di cambiare il passato andando indietro nel tempo? Niente fantascienza, né DeLorean: solo meccanica quantistica. Un gruppo di scienziati della Cambridge University ha condotto una simulazione che potrebbe aprire nuovi orizzonti nel campo della fisica. Ma vediamo con calma.

Once reductionist entanglements are sufficiently disentangled through experimental measurements or observations, science finds the summated, bigger picture of everyday reality it started from as the curiosity to look.

Yesterday we finished a fantastic 3-day workshop with our friends from Ottawa. This was the 2023 annual meeting of the Max Planck - uOttawa Centre for Extreme and Quantum Photonics, at the @MPI_ScienceOfLight .

We heard about #topological #photonics, #metasurfaces, #entanglement, #ultrafast laser pulses, solar #lasers, #neuromorphic computing, #Artificialntelligence for optics and many more exciting topics at the cutting edge of photonics.

Our minds love to measure, organize, and create rules. If I am here and you are there, there is a quanitifiable amount of space between us.

And yet distance is no more than an illusion that allows us to operate as separate beings, apart from each other, the Earth, and the rest of the Universe.

There is no separation.

So, what purpose does the illusion of separateness serve?

Derivation of the correlation coefficient for a two channel Bell-test #experiment:

#Simulation employing only action by contact (no ‘#entanglement’):

The derivation is done with #probability theory, employing no #quantum #physics whatsoever. It is shown that Bell, Clauser, et al., compute correlation coefficients incorrectly.

Physicists Discover ‘Unobservable’ Phase Transition in Quantum Entanglement" #quantum #physics #entanglement

My solution to this Bell test fiasco is quite correct. Any errors are trivial details. The whole thing is really quite a simple and actual rather lovely random process. My IEEE technote-style paper is coming along nicely and shows (w/o QM) that the correlations are invariant under in-unison rotations of the PBS/magnets/etc.

But it has nothing to do with the utter fantasy called "#entanglement", and #quantum #physics is revealed to be the work of dunderpated jackalopes such as Bell and CHSH.

A challenge for #electronics #hobby buffs:

If you look at the the #Ada program (with translations to other languages) in my pinned toots, you will see that the #entanglement of #quantum stuff is actually just the correlations of phase-diffed sinusoids randomly sampled.

So here is your challenge: make QUBIT circuits out of op-amps or 555 timers.

(I plan maybe to get to this myself, but I only dabble a bit, and my electronics bench is covered with unrelated garbage since early in the pandemic.)

Scientists have observed a new phenomenon called quantum superchemistry, where two molecules interact without touching each other. The phenomenon occurs when the molecules are in a quantum state called entanglement, which means they share a quantum connection even when they are far apart. The phenomenon could have implications for quantum computing, sensing, and communication.

I added "A post at the end of summer holiday" to my digital fallow, where I wrote about summer holiday, creating personal digital archives, creating stickers and listening to dub in the heat, and a bit on how less stress is more quality of life.

While cleaning up my digital archives, I came across an older note that wasn't in the wiki, on "Practicing Entanglement".

The thing wasn't finished, but I re-found plenty of nice things in it in how to have a gentler engagement with one's own environment. The photo is from a little informal shrine in a park in Tokyo, that I shot in 2000.

Ugly overhead transmission lines eating their way into the landscape

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

Quantum magic can bend spacetime, according to a new theory. The theory proposes that quantum entanglement, the phenomenon that links two particles across any distance, can also warp the fabric of space and time. The theory could help resolve the paradoxes between quantum mechanics and general relativity, and open new possibilities for quantum technologies. #quantum #spacetime #entanglement

Today was Bell Theorem Day here! I've just shown my students the CHSH game for the first time in their lives. I always feel honored and privileged to be the one who tells them about such a profound fact of nature for the first time. Classical logic is just an artificial human construct, and nature does not "think" that way!

On Wednesday Tatiana Vovk explained to me how the character of environment measurements influences the #entanglement of the realized #quantum trajectory.

When you simulate #markovian dynamics of an open system through such trajectories better use #homodyne operators instead of number measurements. Unless, that is, you want to generate volume law entanglement in most of your trajectories 😂 Then do the latter. 😊

The #NTU fellowship that funds my travel is about bridging the gap between theory and experiments so yeah here's a picture of the turbulent water of the river Inn which is literally the meaning of Innsbruck - the bridge over the Inn.

It is really difficult to make the point that, if the logical foundation of an #experiment is fallacious, then the experiment simply DOES NOT demonstrate what the experimenter claims it does.

This is why the experiments, supposedly showing "#quantum non-locality", in fact show nothing of the sort.

Indeed, the results of these experiments ARE NOT EVEN INTERESTING.

Their was never any "#entanglement" in the first place. You simply have two light signals that have a common cause.

#Entanglement of dissimilar #particles! Previously, #physicists were only able to entangle identical particles.
