AMD boffins come up with better quantum computing architecture

You must teleport the quantum cats

AMD boffins 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 and a bit of theoretical teleporting.

According to Tom's Hardware 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 has the racey title "Look Ahead Teleportation for Reliable Computation in Multi-SIMD Quantum Processor," and says it can 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 reducing the number of qubits needed to perform complex calculations using 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. 

AMD's patent also includes a look-ahead processor embedded into the architecture, tasked to analyze the input workload, predict what steps can be tackled in parallel (and those that can't), and appropriately distribute the workload across qubits, using a quantum teleporting technique to deliver them to the required quantum processing, SIMD-based region. How this quantum teleportation occurs isn't described in the patent and it is not clear if AMD has worked out how to energise itself yet.
