Electron Wave Function
... The founders of QM acknowledged that waves could be caused by the motion of subatomic particles. But, with little evidence if any, Heisenberg also proclaimed that if anyone had knowledge of a particle’s location, then the particles must be in motion. The Heisenberg Uncertainty Principle was formulat ...

Quantum Measurements with Dynamically Bistable Systems
... The dynamic bistability of the oscillator is advantageous for measurements. The idea is to make the oscillator switch between the states depending on the value of the parameter to be measured. Switching leads to a strong change in the system that can be easily detected, leading to a high signal-to-n ...
