Abstract:
Quantum computers with few to tens of qubits now exist based on several technology platforms, and the assertion of quantum supremacy appears imminent based on recent reports. Nevertheless, the task of scaling up to a universal quantum computer to handle real world problems (deemed intractable for classical computers) remains a daunting challenge. Increasing the number of qubits whilst maintaining a manageable error rate is a key current pursuit. In this talk, I will introduce our recent efforts to establish the capabilities for building spin-valley qubits based on layered 2D semiconductors. The unique spin-valley coupling in such materials is expected to suppress decoherence since a spin flip requires the concomitant change of valley. In addition, their compatibility with electrostatically-gated planar qubit architectures are desirable for reducing system complexity and hence scalability. I shall present some of our recent device results leading toward this goal.
