A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.220010 considers optical logic gates in future computers. If you are reading this on your smartphone, its CPU (central processing ...

The processor in a quantum computer. The quantum chip contains the qubits as well as the quantum logic gates that manipulate the qubits. This differs dramatically from a classical computer where the ...

A soft material performs NAND logic with visible light, showing a path toward materials that process information without conventional electronic circuitry. “This project has been part of my scientific ...

Before we plunge headfirst into the fray with gusto and abandon (and aplomb, of course), let’s remind and reassure ourselves that—although the following discussions focus on the devices and ...

Why it matters: For decades, scientists have dreamed of building computer chips that use light instead of electricity to process information. While our current silicon chips are incredibly fast, ...
