Returns a multiply-controlled unitary operation $U$ that applies a unitary $V_j$ when controlled by n-qubit number state $\ket{j}$.
$U = \sum^{2^n-1}_{j=0}\ket{j}\bra{j}\otimes V_j$.
function MultiplexerBruteForceFromGenerator (unitaryGenerator : (Int, (Int -> (Qubit[] => Unit is Adj + Ctl)))) : ((Microsoft.Quantum.Arithmetic.LittleEndian, Qubit[]) => Unit is Adj + Ctl)
Input
unitaryGenerator : (Int,Int -> Qubit[] => Unit is Adj + Ctl)
A tuple where the first element Int
is the number of unitaries $N$,
and the second element (Int -> ('T => () is Adj + Ctl))
is a function that takes an integer $j$ in $[0,N-1]$ and outputs the unitary
operation $V_j$.
Output : (LittleEndian,Qubit[]) => Unit is Adj + Ctl
A multiply-controlled unitary operation $U$ that applies unitaries
described by unitaryGenerator
.
