Amazon's researchers claim their chip, Ocelot, can be much more efficient in using qubits, the fundamental building block of quantum computing, in an approach akin to traditional chip transistors. In a technical research article in this week's Nature magazine, lead author Harald Putterman of Amazon's AWS Center for Quantum Computing in Pasadena, Calif., and colleagues explain how the use of analog circuits, rather than digital ones and zeros, can drastically reduce the number of...
