Absorption-based Quantum Communication with NV centres
Burkhard Scharfenberger, Hideo Kosaka, William J. Munro +1
We propose a scheme for performing an entanglement-swapping operation within a quantum communications hub (a Bell like measurement) using an NV centre's $|\pm 1\rangle \leftrightar…
Photonic Quantum Networks formed from NV- Centers
Kae Nemoto, M. Trupke, S. J. Devitt +4
In this article we present a simple repeater scheme based on the negatively-charged nitrogen vacancy centre in diamond (NV-). Each repeater node is built from simple modules compri…
Coherent control of an NV center with one adjacent 13C
Burkhard Scharfenberger, William J. Munro, Kae Nemoto
We investigate the theoretically achievable fidelities when coherently controlling an effective three qubit system consisting of a negatively charged nitrogen vacancy (NV) cent…
Momentum classification of SU() spin chains using extended Young Tableaux
Burkhard Scharfenberger, Martin Greiter
Obtaining eigenvalues of permutations acting on the product space of representations of SU() usually involves either diagonalising their representation matrices on total-wei…
Fractional spin liquid hierarchy for spin S antiferromagnets
Burkhard Scharfenberger, Ronny Thomale, Martin Greiter
We propose a hierarchy of spin liquids with spin S, which are generated via a Schwinger boson projection from 2S (Abelian) chiral spin liquids with S=1/2. We argue that the P and T…
Spontaneous Parity Violation in a Quantum Spin Chain
Stephan Rachel, Dirk Schuricht, Burkhard Scharfenberger +2
We report on a spontaneous breakdown of parity in the ground state of a spin Hamiltonian involving nearest-neighbor interactions. This occurs for a one-dimensional model where spin…
Geometric phases in semiconductor spin qubits: Manipulations and decoherence
Pablo San-Jose, Burkhard Scharfenberger, Gerd Schön +2
We describe the effect of geometric phases induced by either classical or quantum electric fields acting on single electron spins in quantum dots in the presence of spin-orbit coup…
