Quantum computing is the next AI and IonQ (IONQ) is the next Nvidia (NVDA), Sylvia Jablonski, the Chief Executive Officer and Chief Investment Officer of Defiance ETFs told CNBC earlier this week.

Why Jablonski Is Bullish on Quantum and IONQ

"AI came out of nowhere, we all thought it was a bubble, and now it has practical applications and is being monetized," the investor said, suggesting that quantum computing can undergo a similar process in the future.

Jablonski noted that the quantum sector's revenue is expected to climb 38% between now and 2028.

IONQ is a quantum-as-a-service company whose customers include Alphabet (GOOG,GOOGL)  and Amazon (AMZN), according to Jablonski. The investor is also bullish on another name in the quantum sector, Rigetti (RGTI).

She views IONQ and RGTI as "speculative buy and hold stocks."

The Recent Price Action of IONQ and RGTI

In the last five days, IONQ is up 13%, while it's down 4% in the last month.

RGTI has dropped 4.7% in the last five days and it's up 7% in the last month.

While we acknowledge the potential of IONQ as an investment, our conviction lies in the belief that some AI stocks hold greater promise for delivering higher returns and doing so within a shorter time frame. If you are looking for an AI stock that is as promising as IONQ but trades at less than 5 times its earnings, check out our report about the cheapest AI stock.
