Dr. Vjačeslavs Kaščejevs

Vyacheslavs Kashcheyevs, associate professor (2013, University of Latvia), Ph.D. in mesoscopic physics (2007, Tel Aviv University) leads a nanoelectronics theory lab at University of Latvia.

Kashcheyevs’ research is focused on developing nanoelectronic elements with atomic and single-electron resolution for fundamental metrology and quantum information. He is known for the theory of a special type of single-electron source – quantum pumps – that has enabled the development of the most precise standards of electrical current. For this achievement, Vyacheslavs Kashcheyevs has been honored by the World Economic Forum in 2013. The works of prof. Kashcheyevs have been included in the annual list of best achievements of Latvian sciences four times. Vyacheslavs Kashcheyevs is internationally recognized expert in single-electron devices, co-author of more than 40 publications that are cited more than 800 times. The theory group led by prof. Kashcheyevs collaborates with leading experimental laboratories in Germany, UK, France, Australia and elsewhere, jointly undertaking research projects in quantum technologies under the European framework programs FP7, Horizon 2020 and EMPIR.

Vyacheslavs Kashcheyevs leads physics olympiads program for high-school students at University of Latvia, is a member the international board of the International Physics Olympiad, and the academic committee of the European Physics Olympiad. For his work with talented students, V. Kashcheyevs has received recognition of the Latvian government.

Brief Summary of Talk

Taming the smallest: single-electron quantum technologies

Quantum technologies is a rapidly developing interdisciplinary area seeking to exploit the unique nature of the laws of quantum physics via nanotechnology for radical improvements in information processing, communication, precision measurements, biomedical sensingand other application areas.  One of the most advanced technologies for nanofabrication is modern semiconductor industry. At low temperatures, electrons confined in artificial semiconductor atoms – quantum dots — can be manipulated on the individual quantum level.  I will give an overview of recent advances in development of single-electron devices, and their existing and potential applications as fundamental standards for electrical and spin current, quantum-limited sensors for time-dependent electrical and magnetic field, and even “flying qubits”.
