Classes

BlockEncodingGate	Block encoding gate of a Hamiltonian h, assumed to be Hermitian and normalized such that its spectral norm is bounded by 1. Output state is Hamiltonian applied to principal input state if auxiliary qubit(s) is initialized to |0>.
BlockEncodingMethod	Block encoding method.
ControlledGate	A controlled quantum gate with an arbitrary number of control qubits.
Gate	Parent class for quantum gates.
GeneralGate	General (user-defined) quantum gate, specified by a unitary matrix.
HadamardGate	Hadamard gate.
ISwapGate	A Clifford and symmteric 2-qubit iSWAP gate. It exchanges the states of two qubits and applies a phase of i to the |01> and |10> states.
IdentityGate	Identity gate.
MultiplexedGate	Multiplexed gate (control qubits select a unitary), generalizing a controlled gate.
PauliXGate	Pauli-X gate.
PauliYGate	Pauli-Y gate.
PauliZGate	Pauli-Z gate.
PhaseFactorGate	Phase factor gate: multiplication by the phase factor \(e^{i \phi}\).
PrepareGate	Vector "preparation" gate.
RotationGate	General rotation gate; the rotation angle and axis are combined into a single vector ntheta of length 3.
RxGate	X-axis rotation gate.
RxxGate	Rxx gate.
RyGate	Y-axis rotation gate
RyyGate	Ryy gate.
RzGate	Z-axis rotation gate
RzzGate	Rzz gate.
SAdjGate	Adjoint of S gate - provides a phase shift of -pi/2.
SGate	S (phase) gate - provides a phase shift of pi/2.
SxGate	The square root of X gate.
TAdjGate	Adjoint of T gate - provides a phase shift of -pi/4.
TGate	T gate - provides a phase shift of pi/4.
TimeEvolutionGate	Quantum time evolution gate, i.e., matrix exponential, given a Hamiltonian h: \(e^{-i h t}\).
