And if I understand what you're proposing, an additional challenge is that you won't know the unitary gate that you want at compile time. All the gates are decomposed during compilation. I think the way to approach this is to solve for the angles needed to decompose that gate as 3 rotations.</P> Tue, 18 Oct 2022 21:14:19 GMT KevinR_Intel 2022-10-18T21:14:19Z https://community.intel.com/t5/Intel-Quantum-SDK/Decomposing-arbitrary-unitaries/m-p/1421730#M7 <P>Does the Quantum SDK compiler contain a method to convert an arbitrary unitary into an approximate representation with native gates?&nbsp; For example there is sometimes a reason to generate a random unitary matrix with the Haar measure.&nbsp; &nbsp;</P> Thu, 13 Oct 2022 17:50:30 GMT https://community.intel.com/t5/Intel-Quantum-SDK/Decomposing-arbitrary-unitaries/m-p/1421730#M7 zgural 2022-10-13T17:50:30Z https://community.intel.com/t5/Intel-Quantum-SDK/Decomposing-arbitrary-unitaries/m-p/1423098#M8 <P>At present, we don't have a way to simply specify a gate by a unitary matrix.
