Idealized States Redux—Multi-Qubit Version

Before learning to precisely manipulate multiple qubits in quantum circuits, like you did with single qubits in Chapter 6, Designer Genes—Custom Quantum States, and Chapter 7, Small Step for Man—Single Qubit Programs, you need to augment your understanding of idealized states.

Idealized States for One Qubit

The idealized states for single qubits are the two ways that it can collapse. Consider, for example, a qubit having five pentagon images/_pragprog/svg-17.png and two triangle images/_pragprog/svg-18.png qubelets (both rotated), as shown in the following ...
