Diamonds may be quantum computing's new 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 challe
