Key Points - Nvidia's NVQLink platform enables quantum computers to operate in a hybrid platform with classical supercomputers. - Rigetti Computing is partnering with Nvidia. - One validation of Rigetti's technology came from the federal government, which invested $100 million in it this year. Quantum computers hold the potential to transform the computing industry in as dramatic a fashion as artificial intelligence, perhaps more so. The promise of these machines is that they will harness quantum mechanics to solve extremely complicated calculations in minutes that would take today's best supercomputers centuries. That potential was a contributing factor to shares of Rigetti Computing(NASDAQ: RGTI) soaring to a 52-week high of $58.15 last year. Since then, though, the stock has tumbled, reaching a 52-week low of $12.53 in March. It still trades near the lower end of that range, despite working with semiconductor chip leader Nvidia to bring quantum computing capabilities to AI supercomputers. Missed Nvidia in 2009? This Rare Signal Is Flashing Again.In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. Continue » The situation appears poised to change, however. The company has made strides that point to a rebound in share price ahead. How Rigetti stands out among competitors The potential power of quantum computers has attracted a number of enterprises, large and small, to the field. What sets them apart are their distinct approaches to constructing quantum devices. At the heart of every quantum computer are qubits -- fundamental units of information that serve the same role as binary bits do in a classical computer. But there are numerous ways to make those qubits, each with advantages and disadvantages, and various players in the
