Decomposition of bipartite and multipartite unitary gates into the product of controlled unitary gates
Lin Chen, Li Yu
We show that any unitary operator on the system () can be decomposed into the product of at most controlled unitary operators. The number can be…

On the Schmidt-rank-three bipartite and multipartite unitary operator
Lin Chen, Li Yu
Unitary operations are physically implementable. We further the understanding of such operations by studying the possible forms of nonlocal unitary operators, which are bipartite o…

Limitations on information theoretically secure quantum homomorphic encryption
Li Yu, Carlos A. Perez-Delgado, Joseph F. Fitzsimons
Homomorphic encryption is a form of encryption which allows computation to be carried out on the encrypted data without the need for decryption. The success of quantum approaches t…
