Evidence of entanglement, or: Is Schrödinger's cat really entangled?
Kedar S. Ranade, Kaled Dechoum
Quantum effects and, in particular, entanglement are by now widely recognized in all areas of physics and related fields. However, we feel that the precise notion of entanglement--…
Quantum phase space functions and relations of entropic localisation measures
Kedar S. Ranade
The concept of quantum phase space offers a view on quantum mechanics, which is different from the standard Hilbert space approach, but which more closely resembles the classical p…
Construction of mutually unbiased bases with cyclic symmetry for qubit systems
Ulrich Seyfarth, Kedar S. Ranade
For the complete estimation of arbitrary unknown quantum states by measurements, the use of mutually unbiased bases has been well-established in theory and experiment for the past…
Cyclic mutually unbiased bases, Fibonacci polynomials and Wiedemann's conjecture
Ulrich Seyfarth, Kedar S. Ranade
We relate the construction of a complete set of cyclic mutually unbiased bases, i. e., mutually unbiased bases generated by a single unitary operator, in power-of-two dimensions to…
Observables can be tailored to change the entanglement of any pure state
N. L. Harshman, Kedar S. Ranade
We show that for a finite-dimensional Hilbert space, there exist observables that induce a tensor product structure such that the entanglement properties of any pure state can be t…
Complete sets of cyclic mutually unbiased bases in even prime power dimensions
Oliver Kern, Kedar S. Ranade, Ulrich Seyfarth
We present a construction method for complete sets of cyclic mutually unbiased bases (MUBs) in Hilbert spaces of even prime power dimensions. In comparison to usual complete sets o…
