Researchers at IIT Madras have identified localizable entanglement (LE) as a robust order parameter for measurement‑induced phase transitions (MIPTs). Their analysis demonstrates universal finite‑size scaling of LE, with a diverging entanglement correlation length ξ_E at a critical measurement probability around p_c≈0.16. The work links MIPTs to classical percolation theory and interprets the transition as a limit on quantum teleportation across a circuit. A two‑ancilla protocol is proposed to experimentally read out entanglement redistribution, offering a practical route to verify the theory.
