deprecations_circuits:
|
|
- |
|
|
Deprecated the :attr:`.Instruction.condition` attribute and the
|
|
:meth:`.Instruction.c_if` method. They will be removed
|
|
in Qiskit 2.0, along with any uses in the Qiskit data
|
|
model. This functionality has been superseded by the :class:`.IfElseOp` class
|
|
which can be used to describe a classical condition in a circuit. For
|
|
example, a circuit using :meth:`.Instruction.c_if` like::
|
|
|
|
from qiskit.circuit import QuantumCircuit
|
|
|
|
qc = QuantumCircuit(2, 2)
|
|
qc.h(0)
|
|
qc.x(0).c_if(0, 1)
|
|
qc.z(1.c_if(1, 0)
|
|
qc.measure(0, 0)
|
|
qc.measure(1, 1)
|
|
|
|
can be rewritten as::
|
|
|
|
qc = QuantumCircuit(2, 2)
|
|
qc.h(0)
|
|
with expected.if_test((expected.clbits[0], True)):
|
|
qc.x(0)
|
|
with expected.if_test((expected.clbits[1], False)):
|
|
qc.z(1)
|
|
qc.measure(0, 0)
|
|
qc.measure(1, 1)
|
|
|
|
The now deprecated :class:`.ConvertConditionsToIfOps` transpiler pass can
|
|
be used to automate this conversion for existing circuits.
|
|
deprecations_transpiler:
|
|
- |
|
|
The transpiler pass :class:`.ConvertConditionsToIfOps` has been deprecated
|
|
and will be removed in Qiskit 2.0.0. This class is now deprecated because
|
|
the underlying data model for :attr:`.Instruction.condition` which this
|
|
pass is converting from has been deprecated and will be removed in 2.0.0.
