New Delhi, July 3 -- SEOUL - Every chip Samsung wants to build at 1nm or below runs into the same problem. The circuit patterns that need to be printed onto silicon are so fine, and light so imprecise, that simply predicting how those patterns will distort has become a computational problem serious enough to slow the entire process down. The company has been trying to fix this for more than a decade with classical computers. Now its IT services affiliate is experimenting with something different.

Samsung SDS - the Samsung Group's system integration arm - disclosed this week that it has joined the internal semiconductor research effort to develop quantum computing algorithms for optical proximity correction, the simulation step that predi...
