Could artificial intelligence help overcome one of quantum computing's biggest roadblocks?
New research from Australia's national science agency has found AI could help solve quantum computing errors. This is a key step which could one day lead to quantum computers solving complex real-world problems.
CSIRO research, published as a letter in Physical Review Research journal, found for the first time that AI could help process and resolve quantum errors known as qubit noise, which are generated by the nature of quantum physics.
Overcoming these errors is widely considered the largest barrier to advanced quantum computers moving from experiment to tool.
In conventional computers, information is stored and processed in "bits," which work on the principles of binary numbers. Each bit can represent either 0 or 1. But quantum computing devices are made up of quantum bits, or "qubits."
These work on the special properties of quantum mechanics, allowing them to represent 0, 1, or both 0 and 1 at the same time. This is anticipated to unlock immense computing power, allowing them to solve problems beyond the reach of conventional computers.
But a qubit's delicate nature also leads quantum computers to generate 'noise," or errors, in their outputs. To overcome this, quantum error correction codes are used to detect and correct errors.
CSIRO implemented an AI neural network syndrome decoder to detect errors and make appropriate corrections. CSIRO's Data61 Quantum Systems Team Leader Dr. Muhammad Usman said this work can efficiently process complex errors from real quantum hardware.
