# AssertProb operation

Asserts that measuring the given qubits in the given Pauli basis will have the given result with the given probability, within some tolerance.

operation AssertProb (bases : Pauli[], qubits : Qubit[], result : Result, prob : Double, msg : String, tol : Double) : Unit
Functors

## Input

bases
Pauli[]

A measurement effect to assert the probability of, expressed as a multi-qubit Pauli operator.

qubits
Qubit[]

A register on which to make the assertion.

result
Result

An expected result of Measure(bases, qubits).

prob
Double

The probability with which the given result is expected.

msg
String

A message to be reported if the assertion fails.

tol
Double

Unit

## Remarks

Note that the Adjoint and Controlled versions of this operation will not check the condition.

## Examples

using (register = Qubit()) {
H(register);
AssertProb([PauliZ], [register], One, 0.5,
"Measuring in conjugate basis did not give 50/50 results.", 1e-5);
}
