Can you send a subarray of qubits as a parameter in Q#?



Is it possible to send array slices of qubits as parameters?
Something like this:


using(q : Qubit[5]){
myOp(q[2:3]);
}

Yes, Q# supports array slicing: https://docs.microsoft.com/en-us/quantum/quantum-qr-expressions#array-expressions. You can use Range data type as an index to create a subarray of elements of the array indexed by elements of the range.


Range



Your example will look like this:


using (q = Qubit[5]) {
myOp(q[2..3]);
}
