Fully qualified name: Std.Canon.ApplyPauliFromInt

operation ApplyPauliFromInt(pauli : Pauli, bitApply : Bool, numberState : Int, qubits : Qubit[]) : Unit is Adj + Ctl

Summary

Applies a Pauli operator on each qubit in an array if the corresponding bit of a Little-endian integer matches a given input.

Input

pauli

Pauli operator to apply to qubits[idx] when bit of numberState in idx position is the same as bitApply.

bitApply

apply Pauli if bit is this value

numberState

Little-endian integer specifying which corresponding qubit in qubits should be operated on

qubits

Quantum register on which to selectively apply the specified Pauli operator

Example

The following applies an X operation on qubits 0 and 2, and a Z operation on qubits 1 and 3.

use qubits = Qubit[4];
let n = 5;
// Apply when index in `bits` is `true`.
ApplyPauliFromBitString(PauliX, true, n, qubits);
// Apply when index in `bits` is `false`.
ApplyPauliFromBitString(PauliZ, false, n, qubits);
