Effect of strain and variable mass on the formation of antibonding hole ground states in InAs quantum dot molecules
Planelles, Josep; Climente, Juan I.; Rajadell Viciano, Fernando; Doty, Matthew F.; Bracker, Allan S.; Gammon, Daniel American Physical Society (2010-10-04)Using four-band k·p Hamiltonians, we study how biaxial strain and position-dependent effective masses influence hole tunneling in vertically coupled InAs/GaAs quantum dots. Strain reduces the tunneling and hence the critical ... -
Hole spin mixing in InAs Quantum Dot Molecules
Doty, Matthew F.; Climente, Juan I.; Greilich, A.; Yakes, Michael; Bracker, Allan S.; Gammon, Daniel American Physical Society (2010)The spin state of 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 no mixing between ... -
Scalable qubit architecture based on holes in quantum dot molecules
Economou, Sophia E.; Climente, Juan I.; Badolato, Antonio; Bracker, Allan S.; Gammon, Daniel; Doty, Matthew F. American Physical Society (2012)Spins confined in quantum dots are a leading candidate for solid-state quantum bits that can be coherently controlled by optical pulses. There are, however, many challenges to developing a scalable multibit information ...
