Amazon announcement That he created his own quantum computer chip, joining Microsoft and Google in a push to take this potentially transformative technology of theory to practice. Ocelot is a prototype intended to test the efficiency of the quantum error correction architecture of Amazon Web Services. Compared to other chip methods, the company claims that Ocelot can reduce the cost of implementing quantum error correction up to 90%.
Quantum IT could solve complicated problems exponentially more quickly than standard computers using quantum bits or qubits, rather than traditional bits that store information from a computer in the form of 1 and 0. Rather than representing only a 1 or a 0, qubits can represent a proportion of the two and 0 at the same time. Ocelot takes a step further with its use of “cat qubits”, named for the famous Schrödinger cat Thought of thought, which can “intrinsically remove certain forms of errors”, according to Amazon.
The error rate is one of the key limits of current quantum computer science, because qubits are so sensitive to tiny changes in their environment. The electromagnetic interference of a WiFi network may be sufficient to disrupt a qubit and make it make mistakes. The addition of more qubits to a chip means faster calculations, but also more errors.
OCELOT consists of five data qubits (chat qubits), five “buffer circuits” to stabilize them and four qubits to detect errors on cat qubits. “We have selected our qubit and our architecture with a quantum error correction as a higher requirement,” said Oskar Painter, director of quantum equipment at AWS. “We think that if we want to make practical quantum computers, the correction of quantum errors must pass first.”
Google said that its willow chip, announced in December, was able to reduce errors as more quit had been added. Ocelot is another step towards reducing errors and the reality of useful quantum computers.
