   Sammanfattning : Entanglement is a key resource in many quantum information schemes and in the last years the research on multi-qubit entanglement has drawn lots of attention. In this thesis the experimental generation and characterisation of multi-qubit entanglement is presented. Specifically we have prepared entangled states of up to six qubits. LÄS MER

3. 2. Preaspiration in the Nordic languages : synchronic and diachronic aspects

   Sammanfattning : Preaspiration—the production of glottal friction at the juncture of a vowel and a consonant—appears to be typologically rare but is an areal linguistic feature of Northwestern Europe. This study contains a survey of the known geographical spread of preaspirated stops, their phonological distribution and phonetic expressions in some Nordic dialects. LÄS MER
