Quantum Computation and Spin Electronics
D. P. DiVincenzo, G. Burkard, D. Loss +1
In this chapter we explore the connection between mesoscopic physics and quantum computing. After giving a bibliography providing a general introduction to the subject of quantum i…
Incoherent Zener tunneling and its application to molecular magnets
Michael N. Leuenberger, Daniel Loss
We generalize the Landau-Zener theory of coherent tunneling transitions by taking thermal relaxation into account. The evaluation of a new generalized master equation containing a…
Spin interactions and switching in vertically tunnel-coupled quantum dots
Guido Burkard, Georg Seelig, Daniel Loss
We determine the spin exchange coupling J between two electrons located in two vertically tunnel-coupled quantum dots, and its variation when magnetic (B) and electric (E) fields (…
Transport and Noise of Entangled Electrons
Eugene V. Sukhorukov, Daniel Loss, Guido Burkard
We consider a scattering set-up with an entangler and beam splitter where the current noise exhibits bunching behavior for electronic singlet states and antibunching behavior for t…
Quantum Computing and Quantum Communication with Electrons in Nanostructures
Daniel Loss, Guido Burkard, Eugene V. Sukhorukov
If the states of spins in solids can be created, manipulated, and measured at the single-quantum level, an entirely new form of information processing, quantum computing and quantu…
Spin Tunneling and Phonon-assisted Relaxation in Mn12-acetate
Michael N. Leuenberger, Daniel Loss
We present a comprehensive theory of the magnetization relaxation in a Mn12-acetate crystal in the high-temperature regime (T>1 K), which is based on phonon-assisted spin tunneling…
