Main takeaways
- Advanced Micro Devices (AMD) plans to make an equity investment in PsiQuantum, the two companies said on November 12, 2026.
- The release gives no amount, no valuation and no closing date. PsiQuantum’s last stated valuation was $7 billion, in September 2025.
- The partnership widens from one AMD chip family, Versal, to AMD’s processors, graphics chips and software.
- A PsiQuantum preprint dated November 10 reports a 6.59 microsecond delay to work out error corrections on an AMD chip. It is not peer reviewed.
- Next: the companies said they will share more at the SC26 conference in Chicago, November 15 to 20.
A joint release from PsiQuantum and Advanced Micro Devices (AMD) on November 12, 2026 widened the two companies’ partnership and said AMD plans to buy shares in https://news.manyworlds.vc/companies/psiquantum/. That would add a listed chipmaker to the company’s backers, and the release does not say how much money comes with it.
The investment takes one sentence of the release: “AMD also plans to make an equity investment into PsiQuantum.” AMD’s cautionary statement at the end of the release lists that plan among its forward-looking statements.
The companies said they will co-design “the computing infrastructure required to operate utility-scale, fault-tolerant quantum computers”. Fault-tolerant means a machine that corrects its own errors as it runs. Utility-scale means one large enough for commercially useful work. Such a machine needs conventional computers beside it to control it and work out the corrections.
PsiQuantum had already selected AMD’s Versal chips to develop its platform, the release said. Versal chips are FPGAs, chips whose circuits can be reprogrammed after they are made. The partnership now also covers AMD’s Instinct graphics processors, its EPYC server processors and its ROCm software.
On applications, the companies said their planned first focus is drug discovery. The release reports initial results in simulating covalent inhibitors, a class of molecules it says is relevant to cancer drug research, run on AMD hardware. It gives no figures for those results.
What have the two companies built together so far?
The release points to one published result: a decoder, the conventional program that reads a quantum computer’s error signals and decides what to correct.
A preprint submitted to arXiv on November 10, 2026 describes a machine-learning decoder called PRISM. The release says PsiQuantum researchers optimized it “working with AMD”. A decoder has to work out corrections faster than the machine produces errors, or the backlog grows and the computation stalls, so its speed is one of the numbers a design is judged on. Running on an AMD VP1902 FPGA, PRISM showed a latency, the delay before an answer, of 6.59 microseconds, the paper’s abstract says. A microsecond is a millionth of a second. The abstract gives no earlier figure to compare that with. A preprint has not been peer reviewed, and the test ran on a conventional chip, not a quantum computer.
Who else backs PsiQuantum?
PsiQuantum is private and builds quantum computers that use particles of light. Its last funding round, the Series E of September 10, 2025, raised $1 billion and valued the company at $7 billion, the company said at the time. New investors in that round included NVentures, the venture capital arm of Nvidia.
PsiQuantum’s chief executive is a former AMD executive. Victor Peng “previously served as President of AMD and as CEO of Xilinx”, a company AMD acquired, the company said on April 30, 2026. He was named chief executive on July 15, 2026.
Why it matters
- Companies: PsiQuantum (private) and Advanced Micro Devices (AMD), listed on Nasdaq.
- For PsiQuantum: the supplier of the conventional chips its platform is developed on (Versal, and now EPYC, Instinct and ROCm) plans to become a shareholder. That ties the control and error-correction side of its machine more closely to AMD.
- For AMD: a planned stake in a quantum company that Nvidia’s venture arm backed in 2025, in the conventional computing that quantum machines need.
- Size: AMD “plans to” invest, and nothing is signed in the release. Until an amount is disclosed, the stake cannot be sized for PsiQuantum’s cash or counted as material to AMD.
- Next date: SC26 in Chicago, November 15 to 20, where the companies said they will share more about the partnership.
