Abstract

The emission energy of our device is pre-selected with an accuracy of about 1 meV by using in-situ EBL applied to a planar sample bonded onto a piezoelectric actuator via flip-chip

Finally we investigate the scaling of the Otto cycle efficiency with the size of the working substance for different values of the electric field.. – The efficiency of the quantum

To measure the state of quantum systems itself for different purposes in quantum information theory, which may be related to the construction of a quantum computer, as well as

17 So far, this approach was implemented with a distrib- uted Bragg reflector (DBR) acting as a backside mirror, which was integrated during the epitaxial growth of the

The effect of the nuclear spin ensemble on the electron spin is described by an effective magnetic field B N , the Overhauser field, which shifts the energy levels of the electron

For a given temperature, the maximal tangle τ max is therefore obtained at a finite optimal value (b/J ) opt of the scaled magnetic field strength as a trade-off between having a

A qubit that is encoded in the photon polarization is closely related to an electron spin qubit via optical transitions in semiconductor quantum dots.. For many applications it
