A quaternary linear code is a linear space over the ring of integers modulo 4. Recent research in coding theory shows that many famous nonlinear codes such as the Nordstrom and Robinson (1967) code ...

Chemists have found that commonly used polymer films containing two dyes can optically store data in a quaternary (four-symbol) code, potentially requiring about half as much space as binary code ...

Case Western Reserve researchers are developing a way to potentially use uorescent dyes to double storage capacity in computers, smartphones and other digital devices. That's a tantalizing prospect at ...
