Practical communication settings for quantum key distribution (QKD) are very complex, and the number of participants should be tunable. Given these, we propose a tunable multi-party high-capacity QKD protocol based on m-generalized Fibonacci sequences and golden coding, where the number of participants can be adjusted adaptively by joining a new participant and revoking an old participant, combining two participant groups into one group. Meanwhile, we construct golden coding to achieve higher capability and fewer interactive communications.
