- If Eve measures Alice’s qubits, then Alice and Bob will know about it. So, Alice and Bob won’t use any of those qubits as their encryption key. So, if Eve knows some of Alice’s zeros and ones, that information won’t be useful to her.
- The following example illustrates the use of the right-distributive law for tensor products:
- When we cross-multiply, we use both the left- and right-distributive laws. In the following equations, one step uses the right-distributive law:
- You can code the circuit...
And the next step uses the left-distributive law:
We use the scalar multiplication law when we combine two qubits’ scalars. Here’s an example:
