Quantum Key Recycling with eight-state encoding (The Quantum One Time Pad is more interesting than we thought)
B. Skoric and M. de Vries
Abstract
Perfect encryption of quantum states using the Quantum One-Time Pad (QOTP) requires 2 classical key bits per qubit.
Almost-perfect encryption, with information-theoretic security, requires only slightly more than 1. We slightly improve lower bounds on the key length. We show that key length
Note: Improved the Key Recycling scheme. Extended the results on key length.
