Scientists Discover Quantum Computing Fault Proof Laws

Like all devices, quantum computers are sometimes prone to making mistakes. However, while this issue could easily be fixed on a regular computer with redundancy, quantum machines could not adopt such a feature.

Researchers at the University of Innsbruck, RWTH Aachen University, and Forschungszentrum Jülich have found a way to protect quantum computer computational operations from errors.

On a typical computer, the redundant data used in the operation helps avoid mistakes. However, due to their different properties, quantum computers only make copies of the data they use.

Researchers have decided to distribute the logical quantum information across several qubits. This is a bit analog of a quantum computer.for First time in history, The research team has implemented a system that performs operations with two logical qubits instead of one. This will prevent these calculations from failing.

The experiment was performed on a small ion trapped quantum computer that processes only 16 trapped atoms, with each cubic occupying 7 of them. However, researchers believe that even if a computer can use a two-qubit system to catch errors, it can be extrapolated to a larger system.

Naturally, such a solution came at the expense of computational power, but quantum computers are still easy. Beyond the usual For operations that are complicated and require precision.

“Fault-tolerant implementations require more work than non-fault-tolerant operations. They add more effort and complexity, but the resulting quality is better,” says research team leader Thomas Mons. Says.

The next step for scientists is to move technology to larger machines and test it with more complex calculations.
