An efficient combination of quantum error correction and authentication. (arXiv:2211.09686v1 [quant-ph])

When sending quantum information over a channel, we want to ensure that the
message remains intact. Quantum error correction and quantum authentication
both aim to protect (quantum) information, but approach this task from two very
different directions: error-correcting codes protect against probabilistic
channel noise and are meant to be very robust against small errors, while
authentication codes prevent adversarial attacks and are designed to be very
sensitive against any error, including small ones.

In practice, when sending an authenticated state …
