Background The Toffoli gate is a 3-input, 3-output classical logic gate. It sends $(x, y, a)$ to $(x, y, a \oplus (x \cdot y))$. It is significant in that it is universal for reversible (classical) computation. The Popescu-Rohrlich box is the simplest example of a non-signaling correlation. It ...

The C10k Problem is a classical computing problem whose name (C10k) is a numeronym for concurrently handling ten thousand connections. "To create QPUs with numbers of qubits up to around 10,000, the current fabrication process can simply be scaled to add more qubits in the same way that they are...

I'm fairly confused about how Grover's algorithm could be used in practice and I'd like to ask help on clarification through an example. Let's assume an $N=8$ element database that contains colors Red, Orange, Yellow, Green, Cyan, Blue, Indigo and Violet, and not necessarily in this order. My go...
