Bases: [`HighLevelSynthesisPlugin`](qiskit.transpiler.passes.synthesis.plugin.HighLevelSynthesisPlugin "qiskit.transpiler.passes.synthesis.plugin.HighLevelSynthesisPlugin")
|
|
|
|
Synthesis plugin for a multi-controlled X gate based on the implementation for MCPhaseGate, which is in turn based on the paper by Vale et al. (2024).
|
|
|
|
See \[1] for details.
|
|
|
|
This plugin name is :`mcx.noaux_v24` which can be used as the key on an [`HLSConfig`](qiskit.transpiler.passes.HLSConfig "qiskit.transpiler.passes.HLSConfig") object to use this method with [`HighLevelSynthesis`](qiskit.transpiler.passes.HighLevelSynthesis "qiskit.transpiler.passes.HighLevelSynthesis").
|
|
|
|
For a multi-controlled X gate with $k$ control qubits this synthesis method requires no additional clean auxiliary qubits. The synthesized circuit consists of $k + 1$ qubits.
