Teleportation, AMD's new bet to make quantum computing more efficient

For a long time and like many other technology companies, AMD has been putting a great deal of effort to push the boundaries of quantum computing today and all of its work has started to pay off as recently the company filed a patent application in which he unveiled a quantum computing processor that would use teleportation.

This new patented technology could solve the stability and efficiency problems facing current systems in quantum computing, although it is clear that the technology may be far from being commercially viable, but this patent application demonstrates AMD's interest in the future.

And it is that at this moment there are two major obstacles stand in the way of quantum development and ultimate quantum supremacy: scalability and stability. Quantum states are fickle matter, so sensitive that they can go wrong with the slightest provocation, and furthermore, the sensitivity of a quantum system tends to increase with the presence of more qubits in a given system. However, a team of AMD researchers has submitted a patent application aimed at a more efficient and reliable quantum computing architecture, thanks to a conventional multi-SIMD (Single Instruction Multiple Data) approach.

According to analysts, If AMD could gain a competitive advantage in quantum computing, the profit potential would be unlimited. AMD CEO Lisa Su has reinvigorated this chip designer and instilled a culture of innovation that has propelled AMD up to 3,200% since taking over the leadership of the company in 2014. According to the request submitted by researchers from the company, AMD is investigating a system that aims to use quantum teleportation to increase the reliability of a quantum system, while simultaneously reducing the number of qubits required for a given calculation.

The objective is to mitigate scale problems and calculation errors due to to system instability:

AMD's patent, entitled "Advance Teleportation for Reliable Computing on a Multi-SIMD Quantum Processor," aims to improve the stability, scalability and performance of quantum computing systems in new and more efficient ways. The company describes a quantum architecture based on quantum processing regions - areas of the chip that contain or may contain qubits, waiting their turn in the processing pipeline.

In fact, AMD's design, while worthy of science fiction, aims to teleport qubits from one region to another, thus allowing workloads that in theory would require execution to be treated with an out-of-order philosophy, since execution in order has dependencies between one instruction and the next, which means that a workload must be processed sequentially. The next steps depend on the complete processing of the previous step and knowing its result before the chip can continue with the calculation.

Therefore, some of the chip's resources (in this case, the qubits) remain idle until it is time to perform the next computational step. In contrast, out-of-order execution analyzes a certain workload, determines which parts depend on previous results and which does not, and executes each step of the declaration that does not require a previous result, thus improving performance thanks to greater parallelism. .

The AMD patent also includes an integrated 'look-ahead' processor in architecture, responsible for analyzing inbound workload, predict which steps can be processed in parallel (and which cannot) and properly distribute the workload among the qubits, using quantum teleportation to route them to the required quantum processing SIMD region. How this quantum teleportation occurs is not described in the patent.

So far, only three companies have been identified in the quantum computer market: IBM, Intel, and Google. This patent application shows that AMD does not intend to leave this field and is also working to develop its technologies there.
