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 (RGTI -5.14%) 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. 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 space are trying different ones. Rigetti uses superconducting qubits as the technology behind its quantum processing units (QPUs), which act as the brain and perform calculations in its machines. Superconducting qubits have the advantage of leveraging existing semiconductor chip manufacturing processes such as optical lithography. Rigetti is pursuing a chiplet-based architecture. This strings together a number of small chips to create the QPU, allowing for faster and more scalable quantum computers. Those attributes make them a compelling choice to combine with Nvidia's proprietary quantum platform, NVQLink. With NVQLink,
