Sharing mutable objects can result in broken invariants, exposure of internal details, and other subtle bugs. To prevent such issues, it is important to control accessibility and aliasing of objects. Dynamic Ownership is an effective way to do so, but its owner-as-dominator discipline is too restrictive: objects are either accessible or not. We propose in(More)
We demonstrate an experimental method for measuring quantum state degeneracies in bound state energy spectra. The technique is based on the general principle of detailed balance and the ability to perform precise and efficient measurements of energy-dependent tunneling-in and -out rates from a reservoir. The method is realized using a GaAs/AlGaAs quantum(More)
