1. 1. Generation and detection of entangled single-photon pairs

   University essay from Uppsala universitet/FREIA

   Author : Gabriella Tesfamichael Habtezion; [2024]
   Keywords : ;

   Abstract : Quantum information technology is an emerging field with important applications such as quantum cryptography and teleportation, quantum imaging and lithography. These applications make use of single photons and pairs of entangled photons. In this work, we experimentally generate and attempt to detect the entangled photons. READ MORE

3. 2. Entanglement in a quantum heat engine

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

   Author : Harald Öhrn; [2020]
   Keywords : Quantum physics; Entanglement; Quantum heat engine; Physics and Astronomy;

   Abstract : In 2015 Jonatan Bohr Brask et al. showed that steady-state entanglement could be generated in two interacting qubits incoherently coupled to thermal baths of different temperatures [1]. READ MORE

4. 3. Quantum teleportation of single-electron states

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

   Author : Edvin Olofsson; [2019]
   Keywords : Quantum teleportation; Quantum information; Quantum physics; Levitons; Floquet scattering theory; Mesoscopic physics; Nanophysics; Electron quantum optics; Physics and Astronomy;

   Abstract : Quantum teleportation is a way to transfer a quantum state between two locations, by utilizing a shared entangled state, measurements and the ability to communicate measurement outcomes between the two locations. This thesis consists of a theoretical investigation of an experiment that would implement quantum teleportation using single-electron states in mesoscopic architectures. READ MORE

5. 4. Sensitivity of Various Qubit Detection Methods in Pr:Y2SiO5

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Author : Vassily Kornienko; [2017]
   Keywords : Rare-earth ion quantum computing; Pr:Y2SiO5; Physics and Astronomy;

   Abstract : The long coherence times of the 4f hyperfine levels of rare-earth-ions gives the possibility to use these as quantum computation devices. Moreover after being doped into a crystal the strong dipole-dipole interaction can be utilized to entangle them. Much work has been done here in Lund to attain as many of the DiVincenzo criteria as possible. READ MORE

6. 5. Quantum Entanglement and Cryptography

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Sean Gray; [2014]
   Keywords : quantum entanglement; information theory; quantum information; quantum teleportation; quantum cryptography; key distribution;

   Abstract : In this paper the features of quantum systems which lay the foundation of quantum entanglement are studied. General properties of entangled states are discussed, including their entropy and relation to Bell's inequality. Applications of entanglement, namely quantum teleportation and quantum cryptography, are also considered. . READ MORE
