Light-based logic: The optical chirality logic gate is made of a nonlinear optical material that generates an output signal that’s dependent on the chirality of the two input beams. (Courtesy: Yi ...

Quantum logic gates between different isotopic species are possible, can be driven by a relatively simple laser system, and can work with precision beyond the so-called 'fault-tolerant threshold' ...

Towards ultrafast logic gates (Courtesy: University of Rochester illustration / Michael Osadciw) The first logic gate to operate at femtosecond timescales could help usher in an era of information ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

Nerve cells have the ability to self-organize into strongly interacting networks, even when grown in a Petri dish. Controlling the geometry of such cell cultures might be all that is needed to set up ...

In a potential quantum computer breakthrough, scientists have shown that entangling atoms from different elements can address the problems of quantum memory errors while functioning within a logic ...

Scientists have for the first time demonstrated improvement in quantum computers by using codes designed to detect and discard errors in the logic gates of such machines. The codes were applied to IBM ...

Biological systems have caught the attention of computer scientists, who have been turning everything from RNA molecules to entire bacterial colonies into logic gates. So far, however, these systems ...
