In this chapter, you will learn about quantum entanglement and how you can use it to your advantage when playing silly games. Thanks to the additional possibilities of quantum theory, there are whole new ways of optimizing your winning strategies.

Measuring Qubits

In Part 1 of this book, you learned that measuring a quantum state forces it to collapse to one of its basis states. For quantum computers and qubits, measuring a qubit in superposition will collapse it to ∣0⟩ or ∣1⟩ depending on the wave function probabilities.

If a qubit is measured and the result ...
