But we are working on supplying users with an easier way to express that gate in the future.</P> Fri, 13 Jan 2023 17:54:58 GMT KevinR_Intel 2023-01-13T17:54:58Z https://community.intel.com/t5/Intel-Quantum-SDK/n-qubit-control-gates/m-p/1445857#M43 <P>Does the SDK have an already built n&gt;2 qubit toffoli gate (so control on more than 2 qubits)?</P> <P>This would be useful, but is awkward to construct from standard gates.</P> Wed, 11 Jan 2023 22:52:40 GMT https://community.intel.com/t5/Intel-Quantum-SDK/n-qubit-control-gates/m-p/1445857#M43 zgural 2023-01-11T22:52:40Z https://community.intel.com/t5/Intel-Quantum-SDK/n-qubit-control-gates/m-p/1446502#M44 <P>For now, the quintrinsics.h only supplies users with the 2-control Toffoli construction so to get more controls you do have to write out the de-composition to 2-qubit gates.
