    "abstract": "We perform a comparison of two protocols for generating a cryptographic key\ncomposed from d-valued symbols: one exploiting a string of independent qubits\nand another one utilizing d-level systems prepared in states belonging to d+1\nmutually unbiased bases. We show that the protocol based on qubits is optimal\nfor quantum cryptography, since it provides higher security and higher key\ngeneration rate.",
