1. 1. Non-linear electronic entanglement witness based on current cross correlations

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

   Author : Samuel Luc M Vermeulen; [2017]
   Keywords : physics; quantum information; entanglement; entanglement witness; Physics and Astronomy;

   Abstract : Demonstration of entanglements of mobile electrons in solid state conductors using minimal entanglement linear witness from electrical current correlations has been given. However, detection of maximally entangled states and some mixed states is lacking if the witness is based on two cross correlation measurements only. READ MORE

3. 2. Generation of the Bound Entangled Smolin State and Entanglement Witnesses for Low-Dimensional Unitary Invariant States

   University essay from Teoretisk fysik

   Author : Emil Nordling; [2010]
   Keywords : quantum mechanics; quantum information science; entanglement; photonics; Smolin state; unitary invariant states;

   Abstract : Quantum entanglement is employed as a resource throughout quantum information science. However, before entanglement can be put to intelligent use, the issues of its production and detection must be considered. This thesis proposes four schemes for producing the bound entangled Smolin state. READ MORE
