Quantum Triplet: Three-Photon Entanglement Confirmed ⚡ экспресс
Original: "Observation of Genuine Tripartite Non-Gaussian Entanglement from a Superconducting Three-Photon Spontaneous Parametric Down-Conversion Source"
For the first time, physicists have convincingly shown that three photons from a special source form a single entangled entity.

Three photons, born in a superconducting device, turned out to be a single whole—their quantum state broke all classical boundaries. This is the first reliable case of three-way entanglement without extra assumptions. A step toward quantum computers where three qubits will be stronger than two.
🎯 The method for generating photon pairs, discovered back in the 1960s, has only recently made it possible to reliably create triples with controlled entanglement.
🎬 In the 'Three-Body Problem' trilogy, three celestial bodies move chaotically and unpredictably, while the three quantum photons in the experiment, on the contrary, demonstrate the highest degree of synchrony.
