Controlling the flow of information in quantum cloners: Asymmetric cloning
V. Buzek, M. Hillery, R. Bednik
We show that the distribution of information at the output of the quantum cloner can be efficiently controlled via preparation of the quantum cloner. We present a universal cloning…
Quantum synthesis of 3D vibrational states of trapped ions
B. Hladky, G. Drobny, V. Buzek
A universal algorithm for a deterministic preparation of arbitrary three--mode bosonic states is introduced. In particular, we consider preparation of entangled quantum states of a…
Reconstruction of Liouvillian Superoperators
Vladimir Buzek
We show how to determine (reconstruct) a master equation governing the time evolution of an open quantum system. We present a general algorithm for the reconstruction of the corres…
Quantum State Reconstruction From Incomplete Data
V. Buzek, G. Drobny, R. Derka +2
Knowing and guessing, these are two essential epistemological pillars in the theory of quantum-mechanical measurement. As formulated quantum mechanics is a statistical theory. In g…
Universal optimal cloning of qubits and quantum registers
Vladimir Buzek, Mark Hillery
We review our recent work on the universal (i.e. input state independent) optimal quantum copying (cloning) of qubits. We present unitary transformations which describe the optimal…
Quantum-state synthesis of multi-mode bosonic fields: Preparation of arbitrary states of 2-D vibrational motion of trapped ions
G. Drobny, B. Hladky, V. Buzek
We present a universal algorithm for an efficient deterministic preparation of an arbitrary two--mode bosonic state. In particular, we discuss in detail preparation of entangled st…
