A framework for quantum homomorphic encryption with experimental demonstration
Yu Zhang, Li Yu, Qi-Ping Su +7
Quantum homomorphic encryption (QHE) is an encryption method that allows quantum computation to be performed on one party's private data with the program provided by another party,…
The Birkhoff theorem for unitary matrices of arbitrary dimensions
Stijn De Baerdemacker, Alexis De Vos, Lin Chen +1
It was shown recently that Birkhoff's theorem for doubly stochastic matrices can be extended to unitary matrices with equal line sums whenever the dimension of the matrices is prim…
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…
