Quantum Error Correction with Uniformly Mixed Ancillae

Abstract (in Japanese) (See Japanese page) 
(in English) It is commonly assumed that ancilla qubits must be in a pure state for successful quantum error correction. We show in our talk that they can initially be in any mixed state if the error operator $\sigma_i$ acts simultaneously on all the physical qubits (fully correlated noise). In particular, they can be in the uniformly mixed state, which makes implementation of our scheme extremely ``cheap''. We also note that 1-qubit gate operations can be implemented easily within the codeword. We demonstrated our scheme by using a liquid state NMR quantum computer.
