Amd Patent Aims To Improve Efficiency Using Quantum Teleportation To Cut Qubit Count

AMD researchers have filed a patent application proposing a multi-SIMD (Single Instruction Multiple Data) system as a means to more efficient and reliable quantum computing. The patent reveals that AMD aims to create a system utilising quantum teleportation to reduce the number of qubits per calculation thus, increasing system reliability. Theoretically, there will be fewer calculation errors and scaling problems with a more stable quantum system.

AMD’s patent aims to tackle the two limiting factors to development which are stability and scalability that suffer as more qubits are introduced into a system. ‘Look Ahead Teleportation for Reliable Computation in Multi-SIMD Quantum Processor’ – the title of the patent, suggests that quantum teleportation is the key to efficient qubit processing. In-order processing requires sequential qubit processing from one region of instruction to the next along a linear pipeline. AMD introduces teleport regions that process qubits out-of-order thus sharing the workload across different regions requiring fewer qubits to be processed sequentially. These teleport regions allow for qubits to be moved between quantum SIMD regions having determined the requirement for sequential processing.

This is controlled by the embedded look-ahead processor that calculates which tasks can and cannot be processed in-order then allocates the input workload across qubits, by quantum teleportation. Furthermore, downstream regions in sequential processing are idle until the data reaches the specific point in the pipeline however, with AMD’s solution more calculations can be executed in parallel as in-order and out-of-order instructions can be distinguished thus, increasing efficiency and stability.

An omission from AMD’s patent is how quantum teleportation functions in these specific regions, perhaps a secret that the company intends to guard closely. What is clear from AMD’s patent is their commitment to quantum computing which is building up to be the next evolution in computing.
