some researchers demonstrated that qubits can be cloned perfectly and at will, as long as each clone is encrypted with a single-use decryption key. you can make unlimited redundant copies, but only ever recover one, since decryption consumes the key. for blockchain / crypto, this opens a genuinely new primitive: quantum-native assets with cryptographic scarcity enforced by physics, not just software. the most immediate application is quantum distributed storage - imagine a quantum ledger where your asset lives on 10 nodes simultaneously, fully encrypted, but only one can ever be unlocked and spent. definitely not production ready, but interesting to see & follow
