EXCERPTS: A new development will help cement the “realness” of quantum entanglement even more. A team of researchers from the University of Ottawa and the Sapienza University of Rome have demonstrated a novel technique that allows the visualization of an entangled pair of photons — particles of light. More accurately, what the scientists have manifested and what they describe in a paper published in Nature Photonics is the wavefunction of this quantum system.
“In our context, we refer to wavefunction as a spatially resolved specification of the state of a quantum system. It tells us everything we can know about the quantum system of interest,” said University of Ottawa postdoctoral fellow Alessio D’Errico. “More precisely, the wavefunction allows us to calculate the probability of any measurement outcome.
“In the case of two entangled photons, knowing the wavefunction will tell us what is the probability of finding, at the same time, one particle in point A and the other particle in point B.”
[...] The resultant image of the wavefunction of these entangled photons is strongly reminiscent of a Yin and Yang symbol, which in Chinese culture represents the concept of interconnected forces. The work has far more value beyond mere aesthetics, however. It also has implications for quantum technologies like quantum computers that rely on wavefunctions and entanglement to operate...
