ApplyPauliFromBitString operation

  • Article

Fully qualified name: Std.Canon.ApplyPauliFromBitString

operation ApplyPauliFromBitString(pauli : Pauli, bitApply : Bool, bits : Bool[], qubits : Qubit[]) : Unit is Adj + Ctl

Summary

Applies a Pauli operator on each qubit in an array if the corresponding bit of a Boolean array matches a given input.

Input

pauli

Pauli operator to apply to qubits[idx] where bitApply == bits[idx]

bitApply

apply Pauli if bit is this value

bits

Boolean register specifying which corresponding qubit in qubits should be operated on

qubits

Quantum register on which to selectively apply the specified Pauli operator

Remarks

The Boolean array and the quantum register must be of equal length.

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 bits = [true, false, true, false];
// Apply when index in `bits` is `true`.
ApplyPauliFromBitString(PauliX, true, bits, qubits);
// Apply when index in `bits` is `false`.
ApplyPauliFromBitString(PauliZ, false, bits, qubits);
