Relation between state-distinction power and disturbance in quantum measurements
Ikko Hamamura, Takayuki Miyadera
The measurement of an informative observable strongly disturbs a quantum state. We examine the so-called information-disturbance relation by introducing order relations based on th…
Limitations on post-processing assisted quantum programming
Teiko Heinosaari, Takayuki Miyadera, Mikko Tukiainen
A quantum multimeter is a programmable device that can implement measurements of different observables depending on the programming quantum state inserted into it. The advantage of…
Incompatibility of quantum channels
Teiko Heinosaari, Takayuki Miyadera
Two quantum channels are called compatible if they can be obtained as marginals from a single broadcasting channel; otherwise they are incompatible. We derive a characterization of…
Relativity of Quantum States and Observables
Leon Loveridge, Paul Busch, Takayuki Miyadera
Under the principle that quantum mechanical observables are invariant under relevant symmetry transformations, we explore how the usual, non-invariant quantities may capture measur…
Anderson localisation in spin chains for perfect state transfer
R. Ronke, M. P. Estarellas, I. D'Amico +2
Anderson localisation is an important phenomenon arising in many areas of physics, and here we explore it in the context of quantum information devices. Finite dimensional spin cha…
