#Photons confined to nanoscale structures merge their spin and orbital angular momentum into a unified property, creating the first novel #entanglement discovered in 20 years. This enriches the #quantum state space available to photons, enabling miniaturized, energy-efficient quantum components via enhancing photon-material interactions in confined spaces.

The smallest-ever force field map of nature.

Physicists have mapped the forces acting inside a #proton, showing in unprecedented detail how #quarks—the tiny #particles within—respond when hit by high-energy #photons.

The new result breaks down #space and #time into a fine grid, allowing simulating how the strong force—the fundamental interaction that binds quarks into #protons and #neutrons—varies across different regions inside the proton.

I've watched many of her excellent videos. This is the one that most reminds me of being in a graduate school course. One where there is a lot of material to get through, the professor has taught the course before, and it's off to the races!

This is why we filled notebooks. Because we knew this stuff was going to be on an exam.

Capturing very special light from the very early universe is a very important project which should hopefully reveal the first stars, as explained by Dr. Becky.

Evidence of ‘Negative Time’ Found in #QuantumPhysics Experiment

Physicists 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"…

Thursday #NoeticSpectrum: When you look at a #Spectrum from a distance color boundaries appear to fade into one-another. When your doing high resolution #Spectroscopy those boundaries can look sharp as a knife. The key word is resolution...or is it ? Zoom in again and the once sharp boundaries appear to start to blend again .What's going on ? Are #Photons maybe not a best probe here ?
Is there an explanation in wave-particle duality ? Something else?
We need to be precise...but there is #Noise-

"Securely Propagating Entanglement at the Push of a Button"

…"#Entanglement, #Einstein's 'spooky action at a distance' … is THE tool of quantum #informationscience.

phys.orgSecurely propagating entanglement at the push of a buttonEntanglement, Einstein's "spooky action at a distance," today is THE tool of quantum information science. It is the essential resource for quantum computers and used to transmit quantum information in a future quantum network. But it is highly sensitive. It is therefore an enormous challenge to entangle resting quantum bits (qubits) with flying qubits in the form of photons "at the push of a button."

Intel Enters the Quantum Computing Horse Race With 12-Qubit Chip

#Intel has built a #quantum #processor called #Tunnel #Falls that it will offer to research labs hoping to make the revolutionary computing technology practical.

The Tunnel Falls processor, announced Thursday, houses 12 qubits, the fundamental quantum data processing elements.

It's a major step in the chipmaker's attempt to develop quantum computing hardware it hopes will eventually surpass rivals.

One notable feature of quantum computing is the tremendous variety of approaches. Intel is using electrons, storing data via quantum mechanical #spin, that's analogous to the two directions a top can spin.

#IBM and #Google are using small electrical circuits of #superconducting materials.

#IonQ and #Quantinuum manipulate #charged #atoms stored in a #trap.

Other approaches involve #neutral atoms and even #photons.
