Quest 4: Quantum composer

Last week, we discussed the states of two quantum bits and which operations you can perform with them. We also learned that there exist entangled quantum states and that they can be used to communicate more efficiently (e.g., by transmitting two bits when sending only a single qubit) and to outperform deterministic or probabilistic strategies at a certain game. This week, we will allow ourselves an arbitrary number of qubits and start composing quantum circuits consisting of many operations and use them to solve interesting problems.
