The properties ``Bit.register`` and ``Bit.index`` are removed. They were deprecated in
|
|
Qiskit 0.25 (released in 2021-04). The qubits and bits now live only in the context of
|
|
a :class:`.QuantumCircuit`. The alternative to the properties is
|
|
to use :meth:`.QuantumCircuit.find_bit` to find all the containing
|
|
registers within a circuit and the index of the bit within the
|
|
circuit.
