Iqis Lecture 3 3 Controlled Not

Let us start by introducing the the most popular quantum logic gate that operates on two qubits it's called

Let's start with notations how do we describe a state of 2

I was telling you that the

... e

... rotations it allows us to construct any rotation whatsoever it's uh it's interesting also to look at the set of gates which will

... how the amount phase shift phase shift header mode and that's true except that i have inserted here the

So that this expression here goes to 0 when phi is equal pi and then again when phi is equal

Previously, we talked about single qubit gates and how they can be used to manipulate the state of a single qubit. Today we're ...

And now that we introduce

... a wonderful example of that i think is the notion of the the square root of
