Phys. Rev. A 68, 034308 (2003) [2 pages]Kraus representation of destruction of states for one quditReceived 25 April 2003; published 29 September 2003 Quantum operations arise naturally in many fields of quantum information theory and quantum computing. One of the simplest examples of quantum operation is the von Neumann–Lüders measurement. Destruction of states in quantum mechanics can be treated as a supplement to the von Neumann–Lüders measurement [P. Caban, J. Rembieliński, K. A. Smoliński, and Z. Walczak, J. Phys. A 35, 3265 (2002)]. We show that destruction of states in one-qudit system is a quantum operation by finding its Kraus representation. © 2003 The American Physical Society URL:
