Don’t care values are treated as

• always 0

• always 1

• either 0 or 1

• ignored

XOR gate behaves like

• equality detector

• inequality detector

• inverter

• buffer

A qubit can exist in

• only 0

• only 1

• superposition of 0 and 1

• only binary states

Bloch sphere represents

• classical bit

• quantum state of a qubit

• logic gate

• circuit

CNOT gate flips target qubit when

• control is 0

• control is 1

• both are 0

• both are 1

Entanglement means

• independent qubits

• correlated qubits

• classical relation

• no relation

Applying Pauli-X twice results in

• inversion

• original state
