All Implemented Interfaces:

Backend

public final class StateVectorBackend
extends Object
implements Backend

State-vector simulator backend for quantum circuits.

Simulates quantum circuits using explicit state vectors and matrix multiplication. Each gate is applied as a unitary transformation, and measurements collapse the state. Suitable for small to medium-sized circuits (up to ~20 qubits).
