Wrocław University of Science and Technology Physics Seminar – 14th of April 2025
We cordially invite you to Wrocław University of Science and Technology Physics Seminar on Monday 14th of April 2025 at 11:15 in room 322, building A-1, where there will be delivered a lecture:
Towards scalable quantum computer based on silicon quantum dots
dr hab. Łukasz Cywiński
Group of Applications of the Fundamentals of Quantum Theory at the Division of Theoretical Physics at IF PAN
Please find an abstract below.
Classical computers are made from semiconductors, but semiconductor-based architectures for quantum computers are still less developed than those based on superconducting circuits, trapped ions, or neutral atoms. I will try to convince you that there are good reasons to still pursue the “semiconductor path” to quantum computers and discuss challenges that need to be overcome on this path. I will also discuss what kinds of interesting physical problems from solid state physics and open quantum system physics one can grapple with, while contributing to a somewhat “engineering-like” task of building a scalable quantum computer. Special attention will be given to recent progress of coherent shuttling of spin qubits over distances of hundreds of nanometers. Achieving such shuttling over ~10 micron distance will clear one major obstacle for scalability of quantum dot based quantum computers.
