Peter Staňo: Quantum computation with gated semiconducting spin qubits
The Institute of Physics of the Slovak Academy of Sciences (IP SAS) invites you to a physics colloquium entitled Quantum computation with gated semiconducting spin qubits, presented by Peter Staňo, who will discuss current status of the field of spin qubites focused on spectral estimation and quantification of noise and its correlations. The lecture is open to the entire scientific community, including researchers, students, and all those interested in contemporary superconductivity and quantum materials.
Quantum computation with gated semiconducting spin qubits
First, I will provide an overview of the field of spin qubits realized with electrons or holes confined in semiconducting nanostructures and electrically controlled by gates. I will introduce basic elements: single-qubit manipulation and measurement, and qubit-qubit interaction, and look at the main achievements and status of the field [1]. In the second part, I introduce some of my interests in this field, related to spectral estimation [2], and the quantification of noise and its correlations [3-7].
