Chapter 6: Understanding Quantum Logic Gates
Quantum logic gates are very similar to their classical counterparts in that they are used to perform operations by manipulating the qubits in such a way that the results serve to provide a solution. Of course, that's about as far as the comparison can go. Classical gates transition the state of a bit from one to the other by a single operation, in this case, flipping the bit value from 0 to 1, or vice versa. Quantum gates, sometimes referred to as qubit gates, are different in part because they perform linear transformations on the qubit in a complex vector space to transition the qubit(s) from one state to another.
The following topics will be covered in this chapter:
- Reviewing classical logic ...
