Abstract
There is provided a method for transmitting a quantum state, performed by a computing device. The method may comprise generating a second quantum state using a first quantum state and a dummy state, encoding the second quantum state, generating a third quantum state by injecting an uncorrectable error into the encoded second quantum state and transmitting the third quantum state to a receiving node.
