Amazon joins the quantum computing race with a chip designed to correct errors
Amazon declared that he created his own quantum computing chip by joining Microsoft and Google In an effort to take this potentially transformative technology from theoretical to practical. Ocelot is a prototype that aims to test the efficiency of architecture to correct Amazon Web Services. Compared to other chip methods, the company claims that Ocelot may reduce the cost of applying quantum correction to up to 90 percent.
Quantum calculations can solve complex problems exponentially more than standard computers, using quantum bits or cubes, not traditional bits that store information on your computer as 1 and 0s. Instead of representing only 1 or 0, the cubes may represent part of 1 and 0 at the same time. Ocelot makes this step further with the use of ‘cats qubits’ called the famous Schrodinger’s cat Thought experiment that can “inherently suppress certain forms of errors,” according to Amazon.
The degree of errors is one of the key limitations of current quantum calculations as the cubes are so sensitive to minutes of changes in their environments. Electromagnetic disturbances from the WiFi network may be sufficient to disrupt Cubit and cause errors. Adding more cubes to chip means faster calculations, but more errors.
Ocelot consists of five cubes of data (cat cubes), five “buffer chains” to stabilize them and four cubes to detect bugs of cat cubes. “We have chosen our QUBIT and architecture with quantum errors as the highest requirement,” says Oscar Painter, director of Quantum Hardware at AWS. “We believe that if we are going to make practical quantum computers, quantum errors should come first.”
Google claims that his Chip Willow, declared in December, is able to reduce errors as more cubes have been added. Ocelot is another step towards reducing errors and turning useful quantum computers into reality.
