Entropy of Quantum Measurements
Stan Gudder
If is a quantum effect and is a state, we define the -entropy which gives the amount of uncertainty that a measurement of provides about . The smaller $S…

Dual Instruments and Sequential Products of Observables
Stan Gudder
We first show that every operation possesses an unique dual operation and measures an unique effect. If and are effects and is an operation that measures , we define…

Sensitivity of entanglement measures in bipartite pure quantum states
Danko D. Georgiev, Stanley P. Gudder
Entanglement measures quantify the amount of quantum entanglement that is contained in quantum states. Typically, different entanglement measures do not have to be partially ordere…
