GHZ State (3 qubits)
Three-way entanglement. All three qubits agree, every single time.
3 qubits · 3 gates
Uniform Superposition
Hadamard on every qubit — all basis states become equally likely.
3 qubits · 3 gates
Grover's Search (2 qubits, |11⟩)
One Grover iteration finds the marked state |11⟩ with certainty.
2 qubits · 12 gates
Quantum Interference
H, then Z, then H again. The phase flip in the middle turns cancellation into reinforcement: the qubit lands on |1⟩ every single time. H·Z·H is exactly X.
1 qubit · 3 gates
Quantum Teleportation
Moves qubit 0’s state onto qubit 2 using entanglement and two classical bits.
