Enum GateType 

pub enum GateType {
    Unitary,
    Measurement,
    Prep,
    Custom(String),
}

Represents a type of quantum or mixed quantum-classical gate.

Variants

Unitary

Unitary gates have one or more target qubits, zero or more control qubits, and a unitary matrix, sized for the number of target qubits.

The semantics are that the unitary matrix expanded by the number of control qubits is applied to the qubits.

The data field may add pragma-like hints to the gate, for instance to represent the line number in the source file that generated the gate, error modelling information, and so on. This data may be silently ignored.

Measurement

Measurement gates have one or more measured qubits and a 2x2 unitary matrix representing the basis.

The semantics are:

• the hermetian of the matrix is applied to each individual qubit;
• each individual qubit is measured in the Z basis;
• the matrix is applied to each individual qubit;
• the results of the measurement are propagated upstream.

This allows any measurement basis to be used.

The data field may add pragma-like hints to the gate, for instance to represent the line number in the source file that generated the gate, error modelling information, and so on. This data may be silently ignored.

Prep

Prep gates have one or more target qubits and a 2x2 unitary matrix representing the basis.

The semantics are:

• each qubit is initialized to |0>;
• the matrix is applied to each individual qubit.

This allows any initial state to be used.

The data field may add pragma-like hints to the gate, for instance to represent the line number in the source file that generated the gate, error modelling information, and so on. This data may be silently ignored.

Custom(String)

Custom gates perform a user-defined mixed quantum-classical operation, identified by a name. They can have zero or more target, control, and measured qubits, of which only the target and control sets must be mutually exclusive. They also have an optional matrix of arbitrary size.

The semantics are:

• if the name is not recognized, an error is reported;
• a user-defined operation is performed based on the name, qubits, matrix, and data arguments;
• exactly one measurement result is reported upstream for exactly the qubits in the measures set.

Trait Implementations

impl Clone for GateType

fn clone(&self) -> GateType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GateType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GateType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for GateType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for GateType

fn eq(&self, other: &GateType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for GateType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
