My last column (“Designing with comparators,” EDN, March 29, 2001, pg 56) discussed basic comparator theory, and this column adds hysteresis to comparators to eliminate multiple switching on the ...

A transistor that operates with photons rather than electrons is often heralded as the next step in information processing, but optical technology must first prove itself to be a viable solution in ...

Fibre optics and optical communications is the use of thin strands of glass for sending information encoded into light over long distances. Total internal reflection prevents light inserted into one ...

For quantum computers to outperform their classical counterparts, they need more quantum bits, or qubits. State-of-the-art quantum computers have around 1,000 qubits. Columbia physicists Sebastian ...
