Figure 1: Light circuits. a, This circuit represents a basic two-qubit quantum logic gate. Blue beam splitters reflect 50% of the incident light, green beam splitters 33%.

The demonstration of a microcavity polariton switch and logic gate that can be controlled by the polarization state of light suggests that a new class of integrated optical devices with highly ...

Did you know you can build fundamental circuits using biological methods? These aren’t your average circuits, but they work just like common electrical components. We talk alot about normal s… ...
