D-Wave's quantum computer reportedly performed a quantum simulation faster than classical computers, simulating quantum dynamics of spin glasses to describe magnetic materials.

Among the most critical components are clock generator circuits, which require low phase noise and low jitter for high-precision operation. Jitter is one of the primary challenges in clock generator ...

When [Miroslav] sent in his ‘guerilla homebrew’ square wave ... The generator is based around a simple astable multivibrator. It doesn’t provide sine waves, but it’s the easiest circuit ...
