What’s it about?

Amazon Web Services (AWS) has introduced Ocelot, its first quantum computing chip that claims to reduce the costs of implementing quantum error correction by up to 90%

But first, what is quantum computing? Unlike regular computers, which use bits (0s and 1s) to process information, quantum computers use qubits, which can exist in multiple states at once. This allows them to solve certain types of problems exponentially faster than traditional computers (IBM).

However, qubits are extremely sensitive to changes in noise. Tiny disturbances like vibrations, temperature changes, Wi-Fi signals, etc. can knock them out of their quantum state, causing errors in calculations, which poses a huge challenge for quantum computing.

How does Ocelot address this? To solve this problem, quantum computers rely on quantum error correction, which spreads information across multiple qubits (called logical qubits) to detect and fix errors. The extra qubits required make it very resource intensive. Ocelot is a prototype that introduces a new approach using cat qubits that are specifically designed to resist errors more effectively. According to AWS, this means that future quantum computers could be smaller, cheaper, and more practical for real-world applications.

One question it left me with:

AWS claims that Ocelot’s approach to error correction could dramatically accelerate the development of practical quantum computers. How long will it take before we see a much wider adoption of quantum computers? And what industries will benefit from this?
