Exact Quantum Query Algorithm for Error Detection Code Verification

Understand

Quantum algorithms can be analyzed in a query model to compute Boolean functions.

• Function input is provided in a black box, and the aim is to compute the function value using as few queries to the black box as possible.
• A repetition code is an error detection scheme that repeats each bit of the original message r times.
• After a message with redundant bits is transmitted via a communication channel, it must be verified.
