Researchers at the University of Ottawa, in collaboration with Danilo Zia and Fabio Sciarrino from the Sapienza University of Rome, recently demonstrated a novel technique that allows the visualization of the wave function of two entangled photons, the elementary particles that constitute light, in real-time.

Using the analogy of a pair of shoes, the concept of entanglement can be likened to selecting a shoe at random. The moment you identify one shoe, the nature of the other (whether it is the left or right shoe) is instantly discerned, regardless of its location in the universe. However, the intriguing factor is the inherent uncertainty associated with the identification process until the exact moment of observation.
The wave function, a central tenet in quantum mechanics, provides a comprehensive understanding of a particle's quantum state. For instance, in the shoe example, the "wave function" of the shoe could carry information such as left or right, the size, the color, and so on.
More precisely, the wave function enables quantum scientists to predict the probable outcomes of various measurements on a quantum entity, e.g. position, velocity, etc.
This predictive capability is invaluable, especially in the rapidly progressing field of quantum technology, where knowing a quantum state which is generated or input in a quantum computer will allow to test the computer itself. Moreover, quantum states used in quantum computing are extremely complex, involving many entities that may exhibit strong non-local correlations (entanglement).
Knowing the wave function of such a quantum system is a challenging taskthis is also known as quantum state tomography or quantum tomography in short. With the standard approaches (based on the so-called projective operations), a full tomography requires large number of measurements that rapidly increases with the system's complexity (dimensionality).
Previous experiments conducted with this approach by the research group showed that characterizing or measuring the high-dimensional quantum state of two entangled photons can take hours or even days. Moreover, the result's quality is highly sensitive to noise and depends on the complexity of the experimental setup.
The projective measurement approach to quantum tomography can be thought of as looking at the shadows of a high-dimensional object projected on different walls from independent directions. All a researcher can see is the shadows, and from them, they can infer the shape (state) of the full object. For instance, in CT scan (computed tomography scan), the information of a 3D object can thus be reconstructed from a set of 2D images.

In classical optics, however, there is another way to reconstruct a 3D object. This is called digital holography, and is based on recording a single image, called interferogram, obtained by interfering the light scattered by the object with a reference light.
The team, led byEbrahim Karimi, Canada Research Chair in Structured Quantum Waves, co-director of uOttawa Nexus for Quantum Technologies (NexQT) research institute and associate professor in the Faculty of Science, extended this concept to the case of two photons.
Reconstructing a biphoton state requires superimposing it with a presumably well-known quantum state, and then analyzing the spatial distribution of the positions where two photons arrive simultaneously. Imaging the simultaneous arrival of two photons is known as a coincidence image. These photons may come from the reference source or the unknown source. Quantum mechanics states that the source of the photons cannot be identified.
This results in an interference pattern that can be used to reconstruct the unknown wave function. This experiment was made possible by an advanced camera that records events with nanosecond resolution on each pixel.
Dr. Alessio D'Errico, a postdoctoral fellow at the University of Ottawa and one of the co-authors of the paper, highlighted the immense advantages of this innovative approach, "This method is exponentially faster than previous techniques, requiring only minutes or seconds instead of days. Importantly, the detection time is not influenced by the system's complexitya solution to the long-standing scalability challenge in projective tomography."
The impact of this research goes beyond just the academic community. It has the potential to accelerate quantum technology advancements, such as improving quantum state characterization, quantum communication, and developing new quantum imaging techniques.

No fuckin way.
Ancient aliens are real I guess.

Does this mean the Daoists were right the entire time? :v Someone needs to tell the pope

So life-balance is an actual phenomenon.

Yeah, they used a beam pump specifically in the shape of a yin yang symbol.

I knew as soon as I first came across this , every midwit incapable of reading past a headline on reddit would coming in hot with their ultra credulous takes about it. not surprised TC was the one rushing in to prove me right.

A phase-only hologram applies a modal transformation to an optical transverse spatial mode via phase encoding and intensity masking. Accurate control of the optical field crucially depends on the method employed to encode the hologram. In this Letter, we present a method to encode the amplitude and the phase of an optical field into a phase-only hologram, which allows the exact control of spatial transverse modes. Any intensity masking method modulates the amplitude and alters the phase of the optical field. Our method consists in correcting for this unwanted phase alteration by modifying the phase encryption accordingly. We experimentally verify the accuracy of our method by applying it to the generation and detection of transverse spatial modes in mutually unbiased bases of dimension two and three.

these Bad Apple shitposts have gone too far

It was from their sources.

This is why I'm taoist

Wings topic

I mean, it should have been clear from the mm scaling in the figure that it couldn't represent two photons.

Damn. Missed opportunity to have used a more hilarious shape.

at my old school, there is an actual class on holography. actual in the sense that it's not for scientists <_<

Four days for this is a gamefaqs record.

Watch the "skeptical" scientists dismiss this out of hand.

The funniest part is that if aliens are anything like humans, this is isn't exactly an unlikely first message.

That's still well above average...it sounds like you're criticizing him but you're actually not?

I'm being gracious, the total is likely closer to half.

Eh think this explains it better than what I have seen in this topic:

https://www.msn.com/en-us/news/technology/quantum-yin-yang-shows-two-photons-being-entangled-in-real-time/ar-AA1fTxnX

But this is crazy that a symbol used for life and life force energy is exactly how qantum entanglement is perceived is mind blowing.

I imagine if Einstein could have seen this he would have come up with some great theories on why.

I think you missed the part that it was designed to look this way...not chance or nature, as several people have mentioned

Dangit, I got real excited for a second.

Wanting to believe is a human flaw and I wish we had the spectral scalpels to carve it out.
