Enum dqcsim::common::types::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.
