Permutation-invariant codes encoding more than one qubit
Yingkai Ouyang, Joseph Fitzsimons
A permutation-invariant code on m qubits is a subspace of the symmetric subspace of the m qubits. We derive permutation-invariant codes that can encode an increasing amount of quan…

Quantum homomorphic encryption from quantum codes
Yingkai Ouyang, Si-Hui Tan, Joseph Fitzsimons
The recent discovery of fully-homomorphic classical encryption schemes has had a dramatic effect on the direction of modern cryptography. Such schemes, however, implicitly rely on…
