1.The Bloch sphere is often used to visualize the spin state of a quantum bit. The north and south poles represent spin-up and spin-down states, respectively. The equator represents an equally likely superposition of spin-up and spin-down. Using this information, match all the Dirac Braket notations that correspond to the Bloch sphere positions. Dirac Braket notations a.|0 b. |1 c. |0 + |1 2 d. |0 |1 2 Bloch sphere North Pole South Pole Equator (please answer north pole,south pole and equator amoung these 4 values)

2.IBM has several quantum computers of different sizes. Their 127-qubit IBM Eagle can represent 3.4E38 states when all qubits are in superposition. How many states can their 433-qubit IBM Osprey represent? Write your answer in scientific notation.

3.What did Einstein believe about the communication of two entangled quanta? Circle all the apply.

He shared Niels Bohr's view

Communication between quanta could not exceed the speed of light

Quanta had pre-determined outcomes

Communication between quanta was instantaneous
