It’s a complicated time for Nvidia (NVDA) as the company moves on from the recent GTC (GPU Technology Conference) week. Shares surged yesterday as a rally swept over the market, but the momentum seems to have subsided since then.

For exceptional returns, you might want to look at quantum computing pure plays like IonQ ( IONQ -2.92%), D-Wave Quantum ( QBTS -6.02%), and Rigetti Computing ( RGTI -3.72%). These companies are still small enough that if one of them hits it big, it has plenty of room to grow a modest investment like $10,000 into $1 million.

The chipmaker NVIDIA held its annual conference in Silicon Valley this week. Among the major announcements: it chose Boston to be the site of its first-ever research center for quantum computing, opening later this year.
