Discussion of solutions of exercises of sheet 2.
Entanglement and teleportation
22 Fevereiro 2021, 16:30 • André Souto
Recap of the previous lecture.
The notion of entanglement.Formal definition via product state.
Examples: The EPR pair, the Bell states, GHZ;
How to create Bell states.
Examples in qiskit.
The power of entanglement:
Teleportation with "distributed Cnot";
Teleportation with entanglement;
systems with more than one qubit

Quantum memories and more than one qubit.
Formal definition, measurement, partial measurement and unitary operations.
Examples of measurement.
Examples of unitary operations: Hadamard, phase shift, rotations, Pauli gates.
Independent operations on qubits and operations over multiple qubits.
Composition of unitary operations.Examples: CNot, Controled-U, Tofolli, swap.
The missing operation: copy.
Proof why it is not possible to copy arbitrary unknown quantum states.

Due to lack of time we used this class to finish the theoretical part by presenting examples of unitary operators and measurements.
