A note on quantum McEliece public-key cryptosystem
Li Yang, Min Liang
Inspired by Fujita's analysis [Quantum inf. & comput. 12(3&4), 2012], we suggest a twice-encryption scheme to improve the security of the original quantum McEliece public-key encry…

Cryptography based on operator theory (I): quantum no-key protocols
Li Yang, Min Liang
We study cryptography based on operator theory, and propose quantum no-key (QNK) protocols from the perspective of operator theory, then present a framework of QNK protocols. The f…

A note on threshold theorem of fault-tolerant quantum computation
Min Liang, Li Yang
Error-correction process has to be carried out periodically to prevent accumulation of errors in fault-tolerant quantum computation. It is believed that the best choice to get maxi…
