1.3.1 Encrypting qubits with the quantum one-time pad
Armed with the density matrix formalism, we are finally ready to delve into our first piece of actual quantum cryptography. Concretely, we will be encrypting qubits using a classical key.
What does it mean to encrypt a qubit? And how could we hope to do so? Let’s have a look!
