More To Quantum Computing Than Qubits

A couple of weeks ago, I posted an article about qubits based on the nitrogen-vacancy (N-V) center in diamond. I’m working on one about qubits based on superconducting loops with Josephson junctions. But it’s important to remember that the qubit technology alone tells only part of the story of a quantum computer. Quantum computers, like conventional computers, need ways to store data and wa... » read more
