App Dev Manager\u00a0Leonard Woody<\/a> breaks down the fundamentals of quantum computing from the perspective of a software developer.<\/p>\n

Continuing from Part 1, let\u2019s create a struct that represents the state of a qubit like below:<\/p>\n

<\/p>\n

Using this struct, we can create a class for a Qubit:<\/p>\n

<\/p>\n

Now we can create a Measure method that is a little more rigorous:<\/p>\n

<\/p>\n

Things start to get interesting when we have multiple Qubits. If they are entangled, we have to track all the possibilities in the system of Qubits could have from a measurement. We can represent this like below:<\/p>\n

<\/p>\n

This curious result leads us to a hint of the power of Quantum Computing. For each qubit added to a quantum system, we need to double<\/strong> the amount of bits to store the state. The table below shows how this quickly gets out of control.<\/p>\n

<\/p>\n

Finally, quantum entanglement leads us to the following curious result:<\/p>\n

<\/p>\n

In other words, the results of measurement for a system of qubits is correlated<\/strong>. When we entangle a system of two qubits into a \u201cBell State\u201d, if you measure 1 on one qubit you will always<\/strong> measure a 1 on the other qubit. The reverse is also true, but you will never<\/strong> get different measurements.<\/p>\n

In these two parts of my blog entry, I have demonstrated what Superposition and Entanglement mean from a quantum computing perspective. In Part 3, I\u2019ll get into quantum operations! \ud83d\ude0a<\/p>\n
