Implementations

impl Gate2x2

pub fn pauli_x() -> Self

Pauli-X (NOT) gate: [[0,1],[1,0]].

pub fn pauli_y() -> Self

Pauli-Y gate: [[0,−i],[i,0]].

pub fn pauli_z() -> Self

Pauli-Z gate: [[1,0],[0,−1]].

pub fn hadamard() -> Self

Hadamard gate: H = 1/√2 [[1,1],[1,−1]].

pub fn phase(theta: f64) -> Self

Phase gate: [[1,0],[0,e^{iθ}]].

pub fn t_gate() -> Self

T gate: phase(π/4).

pub fn s_gate() -> Self
