PIB announced on 3 October a 5.56 kilometre free-space quantum key distribution trial conducted on the night of 27–28 September. The architecture combines hardware QKD with software post-quantum cryptography and quantum random number generation. It is a demonstrated test link, not evidence of a nationwide operational network.[1]
