Enum Instrument

pub enum Instrument {
    Effects(Vec<Process>),
    ZMeasurement {
        pr_readout_error: f64,
    },
}

Represents a quantum instrument; that is, a process that accepts a quantum state and returns the new state of a system and classical data extracted from that system.

Variants

Effects(Vec<Process>)

The effects of the instrument, represented as completely positive trace non-increasing (CPTNI) processes.

ZMeasurement

An instrument that measures a single qubit in the $Z$-basis, up to a readout error (probability of result being flipped).

Primarily useful when working with stabilizer states or other subtheories.

Fields

pr_readout_error: f64

Probability with which a result is flipped.

Implementations

impl Instrument

pub fn sample(&self, idx_qubits: &[usize], state: &State) -> (usize, State)

Samples from this instrument, returning the measurement result and the new state of the system conditioned on that measurement result.

pub fn as_json(&self) -> String

Returns a serialization of this instrument as a JSON object.

Trait Implementations
