Implementation of quantum key distribution surpassing the linear rate-transmittance bound
Quantum key distribution (QKD)1,2 offers a long-term solution to secure key exchange. Due to photon loss in transmission, it was believed that the repeaterless key rate is bounded by a linear function of the tran...
