Digital design with combinatorial gates like AND, OR, and NOT gates is relatively straightforward. In particular, when you use these gates to form combinatorial logic, the outputs only depend on th… ...

If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs, sw… ...

A C-NOT logic gate requires two input photons. So the circuit works by zapping the quantum dot twice, generating two photons. These are identical because they’ve come from the same dot.

To gate an integral clock pulse sequence from a continuous source without distorting pulse duration and number is not a trivial task. In most cases, a simple AND gate will cause problems, see Figure 1 ...
