Nvidia's more attractive share price valuation, combined with its many other strengths, makes it the superior quantum computing investment. That said, Nvidia stock is on fire, having hit a 52-week high of $174.25 on July 18. As a result, you may want to wait for its share price to drop before buying.

NVIDIA Corporation’s NVDA shares have risen 27.1% so far this year, mainly due to its advances in artificial intelligence (AI). Meanwhile, D-Wave Quantum Inc. QBTS has seen an even larger increase in its share price,

Quantum Computing stock won't win the title of most creative name in its sector, but it's the best performing of the four quantum computing stocks over the past year. Some investors believe it could be the next Nvidia, a stock that has jumped 100x over the last decade, recently reaching a market cap of $4 trillion.

IonQ has hired former JPM head of applied research Marco Pistoia as its senior vice president of industry relations. Rosenblatt Securities sees IONQ stock hitting $70 in the coming months.

While the artificial intelligence (AI) race is still ongoing, another arms race is emerging: quantum computing. Quantum computing could represent a significant technological leap, enabling the rapid and efficient solution of problems that were previously unsolvable.

With Nvidia's involvement in the space, does that make it a smart quantum computing stock to buy now? After all, the relevance of quantum computing is still likely years away. Where to invest $1,000 right now?
