Fast spin rotations by optically controlled geometric phases in a quantum dot
Erik D. Kim, Katherine Truex, Xiaodong Xu +5
We demonstrate optical control of the geometric phase acquired by one of the spin states of an electron confined in a charge-tunable InAs quantum dot via cyclic 2pi excitations of…
Hole Spin Mixing in InAs Quantum Dot Molecules
M. F. Doty, J. I. Climente, A. Greilich +2
Holes confined in single InAs quantum dots have recently emerged as a promising system for the storage or manipulation of quantum information. These holes are often assumed to have…
All-Optical Ultrafast Control and Read-Out of a Single Negatively Charged Self-Assembled InAs Quantum Dot
Erik D. Kim, Katherine Smirl, Yanwen Wu +6
We demonstrate the all-optical ultrafast manipulation and read-out of optical transitions in a single negatively charged self-assembled InAs quantum dot, an important step towards…
Electric field tunable exchange interaction in InAs/GaAs coupled quantum dots
Kushal C. Wijesundara, Mauricio Garrido, Swati Ramanathan +4
Spin manipulation in coupled quantum dots is of interest for quantum information applications. Control of the exchange interaction between electrons and holes via an applied electr…
Control of the direction and rate of nuclear spin flips in InAs quantum dots using detuned optical pulse trains
S. G. Carter, A. Shabaev, Sophia E. Economou +3
We find that detuning an optical pulse train from electronic transitions in quantum dots controls the direction of nuclear spin flips. The optical pulse train generates electron sp…
Characterization of the Shell Structure in Coupled Quantum Dots through Resonant Optical Probing
Mauricio Garrido, Kushal C. Wijesundara, Swati Ramanathan +4
Excited states in single quantum dots (QDs) have been shown to be useful for spin state initialization and manipulation. For scalable quantum information processing it is necessary…
