Early examples of computers were almost exclusively based on mechanical devices. Although electronic computers became dominant in the past 60 years, recent advancements in three-dimensional ...

We experimentally demonstrate a reconfigurable electro-optic directed logic circuit which can perform any combinatorial logic operation using cascaded carrier-injection micro-ring resonators (MRRs), ...

A team led by the Shenzhen International Quantum Academy reports demonstrating logical operations on a silicon-based quantum processor for the first time, a result that separates encoded, ...
