Struct roqoqo::operations::MeasureQubit

pub struct MeasureQubit {
    qubit: usize,
    readout: String,
    readout_index: usize,
}

Measurement gate operation.

This Operation acts on one qubit writing the result of the measurement into a readout. The classical register for the readout needs to be defined in advance by using a Definition operation.

Note

Here, it is a measurement in terms of quantum mechanics. The obtained result of a $\textit{single}$ measurement will be either a 0 or a 1.
In order to be able to derive probabilities in the $\textit{post-processing}$, the actual measurement needs to be repeated lots of times.

Fields

qubit: usize

The measured qubit.

readout: String

The register for the readout.

readout_index: usize

The index in the readout the result is saved to.
