cirq.with_key_path_prefix

Prefixes the path to the target's measurement keys.

cirq.with_key_path_prefix(
    val: Any, prefix: Tuple[str, ...]
)

The path usually refers to an identifier or a list of identifiers from a subcircuit that used to contain the target. Since a subcircuit can be repeated and reused, these paths help differentiate the actual measurement keys.

val The value whose path to prefix.
prefix The prefix to apply to the value's path.
