Artificial intelligence has proven revolutionary, but quantum computers hold the promise of elevating the computing industry to unprecedented heights, thanks to the power of quantum mechanics. This makes companies working on the tech compelling investments.One of the prominent pure-play quantum companies is IonQ (IONQ -0.26%). It's pursuing the use of particles called ions to operate its quantum machines. This is a newer technology compared to the tried-and-true technique of superconducting qubits employed ...
