Their framework, outlined in a paper published in Nature Physics, specifically proposes the construction of quantum codes that are defined on spheres. "In graduate school, I was part of a team of ...

"Our quantum error-correcting code has a greater than 1/2 code rate, targeting hundreds of thousands of logical qubits," explains Kasai. "Moreover, its decoding complexity is proportional to the ...

QUANTUM COMPUTERS, which exploit strange properties of the subatomic realm to crunch numbers in powerful new ways, do not actually work yet. But if and when they do start working, they will be able to ...
