Google Says Its Quantum Computer Reduces Errors In A Major Breakthrough
readwrite, Wednesday, September 11th, 2024
Google's quantum computer reduces errors as it scales up, improving problem-solving. The computer uses "logical qubits" with error correction, increasing their reliability. Google's research shows a logical qubit with 105 physical qubits outperforms one with 72.
Google has reportedly developed a quantum computer that makes fewer errors as its size increases, potentially setting the stage for devices capable of addressing practical, real-world issues for the first time.
What is quantum computing?
Quantum computers use quantum bits, or qubits, which are subject to quantum physics, yet often need error correction to fully realize their problem-solving capabilities. To correct mistakes, multiple faulty qubits are combined to make them reliable. This is called logical qubits which are then used to perform calculations. In the past, it was said that these logical qubits made calculations worse and didn't fix the issue.
