At it's lowest levels, computation is usually formulated via boolean logic which, in turn, makes use of logical connectives like $\wedge,\vee, \neg$ along with the binary digits $1$ and $0$, representing true and false respectively.

There is, however, an alternative: linear algebra. By representing $0$ and $1$ as vectors and logical operations/gates as matrices, we can define computation in the language of linear algebra. While at first this may seem to be nothin g but a novel construction, this reformulation is precisely what opens the door to quantum computing.

## 0 and 1 states

Instead of $0$ and $1$ or `true` and `false`, we instead represent our basic states as the two standard basis vectors in 2-dimensions:

And so, we can denote the unique inverse of $R$ as simply $R^{-1}$. As an example, the composition "is child of" $\circ$ "is parent of" returns "is you" (i.e. the identity relation). As such, they are inverses of each other.

[^f5]: A modern objector might point to quantum mechanics as producing indeterministic behavior that cannot be deterministically computed but, this is easily dealt with by simply considering the probability distribution of different thoughts a person might have rather than just one thought. On top of this, the human mind is almost certainly not sensitive enough to quantum fluctuations (at least locally) to make this an issue considering it operates on the level of neurons, which are many orders of magnitude larger than anything quantum.
