Namespace: Microsoft.Quantum.Canon

Package: Microsoft.Quantum.Standard

Applies a unitary operation on the target register, controlled on a a state specified by a given bit mask.

operation ApplyControlledOnBitString<'T> (bits : Bool[], oracle : ('T => Unit is Adj + Ctl), controlRegister : Qubit[], targetRegister : 'T) : Unit is Adj + Ctl

Input

bits : Bool[]

The bit string to control the given unitary operation on.

oracle : 'T => Unit is Adj + Ctl

The unitary operation to be applied on the target register.

controlRegister : Qubit[]

A quantum register that controls application of oracle.

targetRegister : 'T

The target register to be passed to oracle as an input.

Output : Unit

Type Parameters

'T

Remarks

The pattern given by bits may be shorter than controlRegister, in which case additional control qubits are ignored (that is, neither controlled on $\ket{0}$ nor $\ket{1}$). If bits is longer than controlRegister, an error is raised.

For example, bits = [0,1,0,0,1] means that oracle is applied if and only if controlRegister is in the state $\ket{0}\ket{1}\ket{0}\ket{0}\ket{1}$.
