Quantum Computers and Error Correction

This development in the field of quantum computing indicates that the technology is capable of handling complex calculations.

Quantum computers use qubits, which are prone to interference and errors.

One approach to error correction is known as surface code correction, which involves introducing redundancy.

Google’s Research into Quantum Error Correction

In 2021, Google announced a working error correction scheme, which resulted in a net increase in errors.

Google has now demonstrated that logical qubits can be increased in size, resulting in a decrease in the overall error rate.

The experiment saw a transition from 3 by 3 grids, involving 17 physical qubits, to 5 by 5 grids using 49 qubits, meaning almost the entire processor was functioning as a single logical qubit.

This increase led to a decrease in error rate from 3.028 per cent to 2.914 per cent.

Fernando Gonzalez-Zalba at the University of Cambridge commented that the research is progressing towards the goal of increasing the size of the logical qubits.

He noted that moving to a 6 by 6 logical qubit requires a big step forward in hardware.

Google’s research into quantum error correction is an important step in the development of quantum computing.

The company’s approach to error correction is scalable, meaning that it could potentially be applied to larger and more complex systems.

This could potentially lead to more powerful quantum computers in the future.
