+
+Qiskit 1.3.2 is a minor bugfix release for the 1.3 series.
+
+<span id="relnotes-1-3-2-synthesis-upgrade-notes" />
+
+### Synthesis Upgrade Notes
+
+*   The high-level synthesis plugins for [`LinearFunction`](/api/qiskit/qiskit.circuit.library.LinearFunction "qiskit.circuit.library.LinearFunction") no longer raise an error when an object other than [`LinearFunction`](/api/qiskit/qiskit.circuit.library.LinearFunction "qiskit.circuit.library.LinearFunction") is passed into the `run` method. Instead, they now return `None`, which is consistent with other plugins. If you relied on this error being raised, you can manually perform an instance-check.

+
+### Bug Fixes
+
+*   Previously, the [`CommutationChecker`](/api/qiskit/qiskit.circuit.CommutationChecker "qiskit.circuit.CommutationChecker") eagerly cached the commutation relations of [`Instruction`](/api/qiskit/qiskit.circuit.Instruction "qiskit.circuit.Instruction")s with float-only `params` as key to query the relation. This could lead to incorrect results if the instruction’s definition depended on additional information beyond just the [`params`](/api/qiskit/qiskit.circuit.Instruction#params "qiskit.circuit.Instruction.params") attribute, as, for example, in the case of [`PauliEvolutionGate`](/api/qiskit/qiskit.circuit.library.PauliEvolutionGate "qiskit.circuit.library.PauliEvolutionGate"). This behavior is now fixed, and the commutation checker eagerly caches commutations only for Qiskit-native standard gates. For custom gates, this change might incur a performance cost; however, guarantees correct results by avoiding unsafe caching.
+
+*   Fixed a bug in the [`CommutationChecker`](/api/qiskit/qiskit.circuit.CommutationChecker "qiskit.circuit.CommutationChecker"), where checking commutation relations of an instruction with non-numeric values in the [`params`](/api/qiskit/qiskit.circuit.Instruction#params "qiskit.circuit.Instruction.params") attribute (as in the case of [`PauliGate`](/api/qiskit/qiskit.circuit.library.PauliGate "qiskit.circuit.library.PauliGate")) could raise an error. Fixed [#13570](https://github.com/Qiskit/qiskit/issues/13570).
+
+*   The [`CommutationChecker`](/api/qiskit/qiskit.circuit.CommutationChecker "qiskit.circuit.CommutationChecker") did not correctly handle commutations of the [`CRXGate`](/api/qiskit/qiskit.circuit.library.CRXGate "qiskit.circuit.library.CRXGate"), [`CRYGate`](/api/qiskit/qiskit.circuit.library.CRYGate "qiskit.circuit.library.CRYGate") and [`CRZGate`](/api/qiskit/qiskit.circuit.library.CRZGate "qiskit.circuit.library.CRZGate") for rotation angles of the form $(4k + 2)\pi$, with $k \in \mathbb Z$. In these cases, these gates were incorrectly assumed to commute with any gate. This behavior is now fixed, and these gates correctly commute with any gate only when the rotation angle is a multiple of $4\pi$.
+
+*   Fixed a bug that caused the following circuit library functions to produce errors when called with `num_qubits=1`: [`efficient_su2()`](/api/qiskit/qiskit.circuit.library.efficient_su2 "qiskit.circuit.library.efficient_su2"), [`real_amplitudes()`](/api/qiskit/qiskit.circuit.library.real_amplitudes "qiskit.circuit.library.real_amplitudes"), [`excitation_preserving()`](/api/qiskit/qiskit.circuit.library.excitation_preserving "qiskit.circuit.library.excitation_preserving") and [`pauli_two_design()`](/api/qiskit/qiskit.circuit.library.pauli_two_design "qiskit.circuit.library.pauli_two_design") (for a single qubit, these circuits do not contain any 2-qubit gates). Fixed [#13480](https://github.com/Qiskit/qiskit/issues/13480).
+
+*   Fixed a bug where any instruction named `"mcmt"` was incorrectly passed to the high-level synthesis routine for a [`MCMTGate`](/api/qiskit/qiskit.circuit.library.MCMTGate "qiskit.circuit.library.MCMTGate"), leading to a failure or an invalid result. This issue could happen, for example, when handling the [`MCMT`](/api/qiskit/qiskit.circuit.library.MCMT "qiskit.circuit.library.MCMT") *circuit*, named `"mcmt"`, and implicitly converting it into an instruction (e.g., when appending it to another circuit). Fixed [#13563](https://github.com/Qiskit/qiskit/issues/13563).
+
+*   Fixed a bug where the default product formula synthesis for [`PauliEvolutionGate`](/api/qiskit/qiskit.circuit.library.PauliEvolutionGate "qiskit.circuit.library.PauliEvolutionGate") did not correctly handle all-identity terms in the operator. The all-identity term should introduce a global phase equal to `-evolution_time`, but was off by a factor of 2 and could break for parameterized times. Fixed [#13625](https://github.com/Qiskit/qiskit/issues/13625). Fixed [#13675](https://github.com/Qiskit/qiskit/issues/13675). Fixed [#13644](https://github.com/Qiskit/qiskit/issues/13644).
+
+*   Fixed an inconsistency in the circuit generated by Pauli evolution synthesis using [`SuzukiTrotter`](/api/qiskit/qiskit.synthesis.SuzukiTrotter "qiskit.synthesis.SuzukiTrotter") or [`LieTrotter`](/api/qiskit/qiskit.synthesis.LieTrotter "qiskit.synthesis.LieTrotter") (the default) method. For parameterized evolution times, the resulting circuits contained parameters with a spurious zero complex part, which affected the output of [`ParameterExpression.sympify()`](/api/qiskit/qiskit.circuit.ParameterExpression#sympify "qiskit.circuit.ParameterExpression.sympify"). The output now correctly contains only real values. Fixed [#13642](https://github.com/Qiskit/qiskit/pull/13642).
+
+*   Fixed a bug that caused [`PauliList.insert()`](/api/qiskit/qiskit.quantum_info.PauliList#insert "qiskit.quantum_info.PauliList.insert") with `qubit=True` to produce a phase attribute with the wrong shape when the original object was of length 1. Fixed [#13623](https://github.com/Qiskit/qiskit/issues/13623).
+
+*   Fixed a bug in [`qasm3.Exporter`](/api/qiskit/qasm3#qiskit.qasm3.Exporter "qiskit.qasm3.Exporter") that caused the exporter to crash when handling a unitary gate due to an incorrect processing of its `params` field. Fixed [#13362](https://github.com/Qiskit/qiskit/issues/13362).
+
+*   Fixed a bug in the [`Target.instruction_supported()`](/api/qiskit/qiskit.transpiler.Target#instruction_supported "qiskit.transpiler.Target.instruction_supported") method where targets with `self.num_qubits==None` would always return `False` independently of the supported basis set.
+
+*   Fixed a bug in the [`UnitarySynthesis`](/api/qiskit/qiskit.transpiler.passes.UnitarySynthesis "qiskit.transpiler.passes.UnitarySynthesis") transpiler pass, where blocks of [`UnitaryGate`](/api/qiskit/qiskit.circuit.library.UnitaryGate "qiskit.circuit.library.UnitaryGate")s on 3 qubits or more were not correctly synthesized. This led, e.g., to the circuit being overwritten with the last processed block or to internal panics when encountering measurements after such a block. Fixed [#13586](https://github.com/Qiskit/qiskit/issues/13586).
+
+*   Fixed a bug in the [`UnitarySynthesis`](/api/qiskit/qiskit.transpiler.passes.UnitarySynthesis "qiskit.transpiler.passes.UnitarySynthesis") transpiler pass where non-2-qubit gates would be included in the available 2 qubit basis, causing the `TwoQubitWeylDecomposition` to panic because of the dimension mismatch.
+
+*   Fixed a bug where initializing [`SparsePauliOp`](/api/qiskit/qiskit.quantum_info.SparsePauliOp "qiskit.quantum_info.SparsePauliOp") with a large number of Pauli-`Y` terms (typically $\geq 100$) and no explicit `coeffs` would result in a coefficient close to 1 but with a floating point error. The coefficient is now correctly 1 per default. Fixed [#13522](https://github.com/Qiskit/qiskit/issues/13522).
