Scientists just found a hidden 48-dimensional world in quantum light

A routine quantum optics technique just revealed an extraordinary secret: entangled light can carry incredibly complex topological structures. Researchers found these hidden patterns reach up to 48 dimensions, offering a vast new “alphabet” for encoding quantum information. Unlike previous assumptions, this topology can emerge from a single property of light—orbital angular momentum.

Unbreakable encryption on the cards thanks to this Chinese team’s discovery

Chinese innovation can pave the way for sharper medical imaging, unbreakable encryption and next-gen sensors.

The latest TechAptitude post explores the highly complex and critical space of Quantum Memory. Quantum Memory performs the delicate balance of storing the quantum state of a photon or other entangled particle without destroying the quantum information of that particle.

I love #scifi so much. I love the absurd assumptions about realworld physics a little less, especially when there are other means toget the same result. #Astrophysics is where smartypants form an #ourobouros konga line of neverending underinformed pop knowledge.
This zine isn't a pro article but I tried to catch some on the misconceptions. Maybe there will eventually be a longer one, physics is SO COOL!

Can you make a neutral pion from two photons?

A neutral pion can decay into two photons. It is therefore not unreasonable to ask the question whether the reverse process – the creation of a neutral pion by colliding two photons – is physically possible and, if not, why not? It is perhaps less reasonable to ask an AI bot these questions. One of my colleagues did just that and found it said “no”, giving  the following three answers to the “why not?” question:

I particularly like the second one.

Would anyone like to offer a correct answer through the comments box?

This will/should/maybe/certainly reach far beyond data storage densities and energies. Its *room temperature* quantum manipulation OR magic OR both.

A team from the University of Konstanz (Germany near Switzerland) has had a bit of a WTF "moment"...

They snapped some light onto some iron crystals and had a beer fueled lunch I hope.

"" despite the substantial volume of research concerning the optical activation of any coherent collective excitation (phonons, magnons, plasmons, and polaritons) in solids, neither a modification of the spectrum ... nor a coupling be-
tween high-momentum and gamma-point modes at fundamental timescales has been reported. """
