AMD to take equity stake in PsiQuantum, widen quantum error-correction work
The companies said they will build a system using AMD CPUs, GPUs and software to correct errors in large-scale quantum computers in real time.
AMD plans to make an equity investment in quantum computing company PsiQuantum, with the amount undisclosed, the two companies said in a joint announcement on November 12. The deal also expands their technical cooperation.
Under the expanded partnership, the companies will develop a system that uses AMD's CPUs, GPUs and software to detect and correct errors in large-scale quantum computers in real time, according to aitimes.com.
PsiQuantum uses photons as qubits and is building machines in Chicago and Brisbane on silicon photonics, aiming for a 1-million-qubit fault-tolerant quantum computer. The company already uses AMD's Versal FPGA, and the cooperation now extends to AMD's EPYC CPUs, Instinct GPUs and ROCm software.
The two firms will also develop applications that combine quantum computing, high-performance computing and AI. They reported early results in cancer drug simulation using AMD GPUs.
Competition in quantum error correction
AMD's move follows earlier work in the same field. In August 2025, AMD began developing next-generation systems combining quantum computing, AI and high-performance computing with IBM. On November 5, AMD unveiled a GPU-based quantum error correction research platform with IBM and Oak Ridge National Laboratory.
Nvidia has also been active: in March 2025 it announced the establishment of a quantum computing research center, and in October 2025 it unveiled NVQLink, which connects quantum processors and GPUs to support real-time error correction.
