Global Optical Control of a Quantum Spin Chain
Brendon W. Lovett
Quantum processors which combine the long decoherence times of spin qubits together with fast optical manipulation of excitons have recently been the subject of several proposals.…
Quantum Computing with Spin Qubits Interacting Through Delocalized Excitons: Overcoming Hole Mixing
Brendon W. Lovett, Ahsan Nazir, Ehoud Pazy +3
As a candidate scheme for controllably coupled qubits, we consider two quantum dots, each doped with a single electron. The spin of the electron defines our qubit basis and trion s…
Creating excitonic entanglement in quantum dots through the optical Stark effect
A. Nazir, B. W. Lovett, G. A. D. Briggs
We show that two initially non-resonant quantum dots may be brought into resonance by the application of a single detuned laser. This allows for control of the inter-dot interactio…
Selective spin coupling through a single exciton
A. Nazir, B. W. Lovett, S. D. Barrett +2
We present a novel scheme for performing a conditional phase gate between two spin qubits in adjacent semiconductor quantum dots through delocalized single exciton states, formed t…
Anticrossings in Foerster Coupled Quantum Dots
Ahsan Nazir, Brendon Lovett, Sean Barrett +2
We consider two coupled generic quantum dots, each modelled by a simple potential which allows the derivation of an analytical expression for the inter-dot Foerster coupling, in th…
