One of these companies' quantum platforms can complete calculations in minutes that would take today's supercomputers longer than the age of the universe to solve.

Quantum computing has the potential of being the next big innovation. At the right size and the right price, it might even be investable.

In a highly speculative quantum computing market, it is judicious for investors to take a wait-and-watch approach before investing in Rigetti and IonQ stocks.

Competition is already heating up, with many companies taking a unique approach to developing their quantum computers. One such company is IonQ ( IONQ -1.43%), a leading manufacturer of quantum computing systems. But is the stock a buy right now? Let's take a closer look.

Trapped-ion quantum computing leader IonQ (NYSE: IONQ) is emerging as a potential leader in the commercialization of quantum computing through its trapped-ion technology approach. Unlike traditional superconducting quantum competitors,
