Real-time Visualization of Quantum Entanglement in Photons

Scientists from the University of Ottawa and Sapienza University of Rome have developed biphoton digital holography, a fast and efficient method for reconstructing the full quantum state of entangled particles. By visualizing the wave function of two entangled photons in real-time, this technique allows for the prediction of outcomes in quantum technology applications. The previous projective measurement approach to quantum tomography was time-consuming and impractical, but the new method requires only minutes or seconds, regardless of the system's complexity, addressing the scalability challenge.
