Imagine shining a flashlight across a dark room. You can predict exactly what the light will do: travel in a straight line ...
"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 error-correcting codes form the cornerstone of reliable quantum information processing. By embedding quantum data into carefully designed subspaces, these codes detect and correct errors ...
