Bose Institute scientists propose 'General Concurrence Percolation' to connect quantum networks efficiently
Scientists at Bose Institute, Kolkata, have proposed a protocol called General Concurrence Percolation (GCP) that can establish long-distance quantum links with lower initial entanglement, the Science Ministry said on 6 August 2026.
Summary
Scientists from Bose Institute, Kolkata, an autonomous institute of the Department of Science and Technology, have introduced a protocol called General Concurrence Percolation (GCP) for connecting quantum networks, the Science Ministry said on 6 August 2026. The work, published in Physical Review A, combines quantum mechanics with percolation theory from statistical physics. GCP uses localised geometric routing to strengthen weak entangled links without disconnecting intermediate stations, allowing long-distance quantum communication with a lower threshold of initial entanglement.
