A recent paper in Nature Communications discusses how to 3D print common logic gates using both macro-scale 3D printing techniques and a much smaller version with microstereolithography.

A new class of logic gates offers robust characteristics, low power consumption, and the ability to run on a very wide range of supply voltages.

You should see a main section of the application where you can start to design your logic circuit. On the left-hand side, there's a selection pane with all of the units you can use for your design, ...

Researchers have reverse-engineered a cellular signal processing system and used it like a logic gate -- a simple computer -- to better understand what causes specific cells to migrate.

Putting a spin on logic gates Research collaboration develops a prototype for a spin-wave majority logic gate that uses wave interference for information processing Date: April 10, 2017 Source ...

The first quantum-logic device made from silicon has been unveiled by researchers in Australia and Japan. Their controlled-not (CNOT) gate, which is a fundamental component of a quantum computer, was ...
