DumpOperation operation

Fully qualified name: Std.Diagnostics.DumpOperation

Q#

operation DumpOperation(nQubits : Int, op : (Qubit[] => Unit is Adj)) : Unit

Summary

Given an operation, dumps the matrix representation of the operation action on the given number of qubits.

Input

nQubits

The number of qubits on which the given operation acts.

op

The operation that is to be diagnosed.

Remarks

When run on the sparse-state simulator, the following snippet will output the matrix $\left(\begin{array}{cc}0.707& 0.707\\ 0.707& -0.707\end{array}\right)$:

Q#

operation DumpH() : Unit {
    DumpOperation(1, qs => H(qs[0]));
}

Calling this operation has no observable effect from within Q#. Note that if DumpOperation is called when there are other qubits allocated, the matrix displayed may reflect any global phase that has accumulated from operations on those other qubits.
