Qubits in 3D and 2D semiconductors

Prof. Dr Guido Burkard

Professor of Physics University of Konstanz, Germany

 

Short abstract:

In this talk, I will first provide a brief introduction into the field of quantum computing, its current state and perspectives. Then, the focus will be on solid-state and specifically semiconductor systems, where the spin of individual or few electrons has been identified as a suitable carrier of quantum information (qubit).


The use of materials with dilute nuclear spin systems such as silicon and carbon has lead to spin qubits with very long coherence times that are routinely in the micro- to millisecond range, in some cases even reaching many seconds. The suppression of magnetic noise from nuclear spins has uncovered the important role of charge fluctuations and the need to shield spin qubits against them.

The last part will be devoted to two-dimensional semiconductors such as gapped graphene or monolayer transition metal dichalcogenides which represent an interesting group of materials that we have studied theoretically in view of their spin-related properties and potential for spin-based quantum computing
