An important non-classical feature of quantum measurements is the celebrated uncertainty trade-off, namely that the uncertainties in the outcomes of measurements performed on distinct yet identically ...

Suppose I throw a stone with my right hand and it travels less than I had expected. This observation can have at least two interpretations: the stone may be heavier than I thought, or my arm may be ...

An experiment conducted at the University of Toronto has thrown a fundamental aspect of the Heisenberg uncertainty principle into doubt. For decades, we’ve believed that you can’t measure a quantum ...

Here we explore the control element known as a disturbance observer—one servo control scheme that works to reject external and internal disturbances. Control systems are typically designed to ...
