AQP -seminaari: Solitary electrons in semiconductor circuits
Aalto Quantum Physics -seminaari (Nanotalo). Puhuja: Slava Kashcheyevs (University of Latvia)
Individual electrons confined to quantum dots and guided along nanowire edges in semiconductors circuits form an exciting quantum technology platform being actively developed for applications in metrology, quantum sensing and quantum computing. The precision of electron counting now rivals even the most accurate electrical measurements putting within the reach direct realisation of the quantum Ampere in the redefined SI. Availability of on-demand electron sources has enabled chip-level collider experiments implementing few-particle quantum optics with interacting fermions.
In the talk, I will discuss the key concepts and recent advances in the field of single-electronics, drawing upon the experience of the Nanoelectronics theory group at University of Latvia in collaboration with experimental laboratories at European National metrology in Germany (PTB) and the UK (NPL).
