The California-based firm said it has achieved a major milestone and teased more news to come. Here’s what to know.

D-Wave Systems Inc., a Canada-based quantum computing company disclosed its roadmap for work on logic gate-model quantum computing systems. Skip to main content Events Video Special Issues Jobs ...

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.

Recently, [Manuel] did a post on making logic gates out of anything. He mentioned a site about relay logic. While it is true that you can build logic gates using switch logic (that is, two switches… ...
