Ground state properties of sub-Ohmic spin-boson model with simultaneous diagonal and off-diagonal coupling
Nengji Zhou, Lipeng Chen, Yang Zhao +2
By employing the variational approach, density matrix renormalization group (DMRG), exact diagonalization as well as symmetry and mean-field analyses, the ground state properties o…
Relaxation of Shallow Donor Electron Spin due to Interaction with Nuclear Spin Bath
Semion Saykin, Dima Mozyrsky, Vladimir Privman
We study the low-temperature dynamics of a shallow donor, e.g., P, impurity electron spin in silicon, interacting with the bath of nuclear spins of the Si isotope. Fo…
Semiconductor quantum computer design with 100 nm separation of nuclear-spin qubits
Vladimir Privman, Dima Mozyrsky
We combine elements of the 1998 quantum computing proposals by Privman, Vagner and Kventsel, and by Kane, with the new idea of nuclear-spin qubit interactions mediated indirectly v…
Quantum computing with spin qubits in semiconductor structures
Vladimir Privman, Dima Mozyrsky, Israel D. Vagner
We survey recent work on designing and evaluating quantum computing implementations based on nuclear or bound-electron spins in semiconductor heterostructures at low temperatures a…
Indirect Interaction of Solid-State Qubits via Two-Dimensional Electron Gas
Dima Mozyrsky, Vladimir Privman, M. Lawrence Glasser
We propose a mechanism of long-range coherent coupling between nuclear spins to be used as qubits in solid-state semiconductor-heterojunction quantum information processing devices…
Decoherence and Measurement in Open Quantum Systems
Vladimir Privman, Dima Mozyrsky
We review results of a recently developed model of a microscopic quantum system interacting with the macroscopic world components which are modeled by collections of bosonic modes.…
