New method to systematically find optimal quantum operation sequences for quantum computers developed

Computer scientists have succeeded in developing a method for systematically finding the optimal quantum operation sequence for a quantum computer. They have developed a systematic method that applies optimal control theory (GRAPE algorithm) to identify the theoretically optimal sequence from among all conceivable quantum operation sequences. This method is expected to become a useful tool …

Silicon image sensor that computes

Researchers have developed the first in-sensor processor that could be integrated into commercial silicon imaging sensor chips — known as complementary metal-oxide-semiconductor (CMOS) image sensors — that are used in nearly all commercial devices that need capture visual information, including smartphones.
