Electron and nuclear spins have been employed in many of the early demonstrations of quantum technology (QT). However applications in real world QT are limited by the difficulty of measuring single sp...
Phase diffusion of a two-component Bose-Einstein condensates: exact and short-time solutions for arbitrary coherent spin state
two-component Bose-Einstein condensates arbitrary coherent spin state
2010/11/23
We investigate phase diffusion of a two-component Bose-Einstein condensates prepared initially in arbitrary coherent spin state |θ0, φ0i. Analytical expression of the phase-diffusion time is presented...
Coherent optical writing and reading of the exciton spin state in single quantum dots
Coherent optical writing reading exciton spin state single quantum dots
2010/10/21
We demonstrate a one to one correspondence between the polarization state of a light pulse tuned to excitonic resonances of single semiconductor quantum dots and the spin state of the exciton that it ...
