The Toffoli gate (CCNOT) flips the target qubit only when both control qubits are |1⟩. Fundamental for reversible computing.

Generates a truly random 4-bit number using quantum superposition. Each qubit is placed in superposition via Hadamard.

Creates a maximally entangled Bell state |Φ+⟩ = (|00⟩ + |11⟩)/√2 using a Hadamard gate followed by a CNOT.
