Effect of matrix parameters on mesoporous matrix based quantum computation [PDF]

open access: yes, 2007
We present a solid state implementation of quantum computation, which improves previously proposed optically driven schemes. Our proposal is based on vertical arrays of quantum dots embedded in a mesoporous material which can be fabricated with present ...

Solution of the Schrödinger Equation for Quantum Dot Lattices with Coulomb Interaction between the Dots [PDF]

open access: yesPhys. Rev. B 62, 8126 (2000), 2000
The Schr\"odinger equation for quantum dot lattices with non-cubic, non-Bravais lattices built up from elliptical dots is investigated. The Coulomb interaction between the dots is considered in dipole approximation. Then only the center of mass (c.m.) coordinates of different dots couple with each other. This c.m.

Polar optical phonons in wurtzite spheroidal quantum dots: Theory and application to ZnO and ZnO/MgZnO nanostructures [PDF]

open access: yesJ. Phys.: Condens. Matter 17, 1085 (2005), 2004
Polar optical-phonon modes are derived analytically for spheroidal quantum dots with wurtzite crystal structure. The developed theory is applied to a freestanding spheroidal ZnO quantum dot and to a spheroidal ZnO quantum dot embedded into a MgZnO crystal. The wurtzite (anisotropic) quantum dots are shown to have strongly different polar optical-phonon

Improving Intrinsic Decoherence in Multi-Quantum-Dot Charge Qubits [PDF]

open access: yesPhys. Rev. B 76, 235309 (2007), 2007
We discuss decoherence in charge qubits formed by multiple lateral quantum dots in the framework of the spin-boson model and the Born-Markov approximation. We consider the intrinsic decoherence caused by the coupling to bulk phonon modes. Two distinct quantum dot configurations are studied: (i) Three quantum dots in a ring geometry with one excess ...

Independent electrical tuning of separated quantum dots in coupled photonic crystal cavities [PDF]

open access: yes, 2011
Systems of photonic crystal cavities coupled to quantum dots are a promising architecture for quantum networking and quantum simulators. The ability to independently tune the frequencies of laterally separated quantum dots is a crucial component of such ...

Unraveling the mesoscopic character of quantum dots in nanophotonics

open access: yes, 2014
We provide a microscopic theory for semiconductor quantum dots that explains the pronounced deviations from the prevalent point-dipole description that were recently observed in spectroscopic experiments on quantum dots in photonic nanostructures. At the
