Amazon Ocelot Quantum Chip: Cat Qubits Explained
Why in the news
Amazon, working with Caltech, introduced Ocelot, its first quantum chip, joining Google and Microsoft in quantum hardware.
Key facts
- Layout: two stacked silicon squares.
- Qubits: five for data storage; four for stability and error correction.
- Cat qubits (named after Schrödinger’s cat thought experiment) reduce computation errors caused by heat, vibration and electromagnetic interference.
- Cost: Amazon says the design cuts costs by 90%.
Significance
- Quantum machines are expected to transform fields like chemistry and healthcare.
- Some experts think real-world uses are still about a decade away.
Exam angle
- Chip: Ocelot; partner: Caltech.
- Error-handling technique: cat qubits.
