Thinking about the quantum internet
Quantum computers deserve their own quantum internet. This is a network that dispatches information not in the form of bits  ones and zeros  but rather as qubits, just like in the quantum computer itself. In the view of Dirk Bouwmeester, a professor in Leiden’s Quantum Matter & Optics research group,…
