Diamonds may be quantum computing's best friend
At the heart of quantum computing is the ability for so-called "qubits," or the atomic-scale building blocks of quantum computers, to inhabit more than one physical state at once. Known as superposition, it's what gives quantum computers their exciting potential.
Superposition can be a real bear to maintain, but this week, MIT researchers announced a new approach developed using synthetic diamonds. Eventually, it could put reliable, working quantum computers within closer reach.
Part of the challenge inherent in quantum computing is maintaining stability. In many other fields that's accomplished via feedback control: With a desired state in mind, researchers measure the current state and make adjustments as necessary to keep the system in line.
