We are a part of the effort in nanoelectronics in the , Department of Applied Physics
Group leader
Our group focuses on the study of quantum effects in superconducting circuits comprising qubits and resonators. This is a remarkably versatile experimental platform, allowing us to dive into fundamental physical phenomena and, in the long term, aiming at applications such as quantum computers and simulators.
Some of our topics of interest:
The high-frequency measurement techniques for the work on superconducting circuits can be employed in other contexts as well. Novel materials have recently been fabricated using nanotechnology. Our goal is to understand how these new types of materials, placed in cavities or in transmission lines, interact with microwave fields.
Some of our topics of interest:
We are interested in phenomena related to tunnelling in Bose-Einstein condensates, and the properties of the phase of the order parameter. We have been investigating many-body fragmented states realized with bosonic atoms in double-well traps as well as Josephson effects in fermionic gases.
The Kvantti group is part of the Low Temperature Laboratory in the Department of Applied Physics. We are located in Nanotalo. We have immediate access to the nanofabrication equipment in the clean rooms of and the national research infrastructure OtaNano, including the and imaging facilities in the .
For measurements at room temperature in a magnetic field, we employ a GMW 76mm electromagnet model 5403 with a Sorensen DKM40-75E power supply. This device is used for testing various samples in magnetic fields and for the characterization of nanomagnetic composites in the microwave range.
The Low Temperature Laboratory at Aalto University is one of the world centres in ultra-low temperature physics and technology. The leading position is based on vigorous in-house development and construction of sub-mK refrigerators.
