Quantum cryptography with continuous alphabet
D. V. Sych, B. A. Grishanin, V. N. Zadkov
abstract: A new quantum cryptography protocol, based on all unselected states of a
qubit as a sort of alphabet with continuous set of letters, is proposed. Its
effectiveness is calculated and shown to be essentially higher than those of
the other known protocols.
