(TomsHardware) A team of researchers with AMD have filed a patent application that looks toward a more efficient and reliable quantum computing architecture, thanks to a conventional multi-SIMD (Single Instruction Multiple Data) approach.
According to the application, AMD is researching a system that aims to use quantum teleportation to increase a quantum system’s reliability, while simultaneously reducing the number of qubits necessary for a given calculation. The aim is to both alleviate scaling problems and calculation errors stemming from system instability.
The AMD patent, titled “Look Ahead Teleportation for Reliable Computation in Multi-SIMD Quantum Processor,” aims to improve quantum stability, scalability, and performance in novel, more efficient ways. It describes a quantum architecture based on quantum processing regions: areas of the chip that hold or can hold qubits, lying in wait for their turn on the processing pipeline. AMD’s approach aims to improve on existing quantum architectures by actually reducing the number of qubits needed to perform complex calculations — via the science fiction-esque concept of quantum teleportation.
AMD’s design aims to teleport qubits across regions, enabling workloads that would theoretically require in-order execution to become capable of being processed in an out-of-order philosophy.

How this quantum teleportation occurs isn’t described in the patent — it looks like AMD is playing its cards close to its chest on this one.
