Ziel
The objective is realising the first silicon single-electron spin quantum bits, which will be a significant step towards the realization of the first generation quantum computers. Quantum computers are expected to dramatically outperform the largest classical supercomputers in solving specific important problems. Applications involve data encryption (for intrinsically secure communication), the efficient simulation of quantum systems (such as chemical reactions), and support in many emerging forms of artificial nanotechnology, and in our understanding of the nanomachinery of biological molecules.
In this proposal CMOS-compatible silicon quantum dots (QDs) are used as hosts for electron spin quantum bits for future solid-state quantum information processing. We will use a unique design which incorporates a large number of independently controllable gates, resulting in an unprecedented degree of tunability in Si QDs. This architecture has allowed for single-electron QDs in silicon. Here, we aim at establishing Pauli spin blockade in the few-electron regime in double QD (DQD) systems, which will be used as detector for single-electron spin resonance. This will enable us to determine the single electron spin coherence time T2, which holds the promise to be extremely long in Si QDs.
