Enum qdk_sim::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

Fields

pr_readout_error: f64

Probability with which a result is flipped.

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.

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

impl Debug for Instrument

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Instrument

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Serialize for Instrument

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.
