Practical quantum somewhat-homomorphic encryption with coherent states
Si-Hui Tan, Yingkai Ouyang, Peter P. Rohde
We present a scheme for implementing homomorphic encryption on coherent states encoded using phase-shift keys. The encryption operations require only rotations in phase space, whic…

Computing spectral bounds of the Heisenberg ferromagnet from geometric considerations
Yingkai Ouyang
We give a polynomial-time algorithm for computing upper bounds on some of the smaller energy eigenvalues in a spin-1/2 ferromagnetic Heisenberg model with any graph for the und…

Computing on quantum shared secrets
Yingkai Ouyang, Si-Hui Tan, Liming Zhao +1
A (k,n)-threshold secret-sharing scheme allows for a string to be split into n shares in such a way that any subset of at least k shares suffices to recover the secret string, but…
