Design a Teleporting Circuit

As the number of qubits in your circuit increases, these analytic methods using gate matrices or tensors break down. Instead, the idea is to identify patterns that guide your design of quantum algorithms. You’ll learn about this more in Chapter 10, ​Quantum Search​. In addition to dealing with the growing size of your circuits, another equally important consideration is figuring out how to properly harness quantum effects and designing your algorithms with them in mind. In this section, we’ll use the methods introduced in this chapter and analyze a teleporting quantum circuit.^[47] This circuit shares many characteristics for down-to-earth applications such as encrypting messages using quantum theory, described in ...
