Nvidia Builds An Ai Superhighway To Practical Quantum Computing Forbes

In the last two weeks, NVIDIA, the enabler and chief beneficiary of the AI craze, has bought into quantum computing. “I'm a little surprised they haven't done it before,” says Richard Shannon, an investment analyst at Craig Hallum. The investments from NVIDIA’s venture capital arm and other investors—which collectively value quantum computing startups Quantinuum, QuEra and PsiQuantum at over $17 billion—represent a shift in tone for NVIDIA’s CEO, Jensen Huang. In January, Huang said that useful quantum computers were 15 to 20 years away, sending publicly-listed quantum computing firms tumbling. He walked this back in March, saying in June that quantum computing had reached an “inflection point” and could “solve some interesting problems in the coming years”. A NVIDIA spokesperson declined to comment.

By positioning itself at the center of the hardware that AI companies need to run their models, NVIDIA has become the world’s most valuable company, valued at $4 trillion. NVIDIA designs GPUs (the chips specialized for running AI algorithms), develops CUDA (which allows the chips to talk to each other), and packages it all into supercomputers the size of fridges—which AI companies are... Quantum computing is unlikely to help NVIDIA’s AI customers. “Quantum computing and AI are sort of diametrically opposed,” said Pete Shadbolt, chief science officer at PsiQuantum, one of the startups that NVIDIA invested in. AI systems are powerful because they learn patterns from vast quantities of data. Quantum computers, by contrast, “hate data, and they love precision,” said Shadbolt.

Proponents believe that quantum computing could usher in a new computing paradigm. Rather than performing numerous simple calculations in parallel, as NVIDIA’s GPUs do, quantum computers could solve a few, extremely valuable equations. Quantinuum does this using ions (charged atoms), PsiQuantum uses photons (light particles), and QuEra uses neutral atoms. These tiny particles obey the strange laws of quantum mechanics: they can be in multiple states at the same time, allowing quantum computers to explore multiple paths of a complex calculation simultaneously, arriving at... This includes shortening the millions of years that it would take classical computers to break the encryption schemes that underlie much of the digital economy to hours, which has sent banks scrambling for “quantum-resistant”...
