Ultrasensitive bolometers
We develop fast and sensitive thermal detectors for circuit quantum electrodynamics applications.
New method of measuring qubits promises ease of scalability in a microscopic package
Aalto University researchers are the first in the world to measure qubits with ultrasensitive thermal detectors—thus evading the Heisenberg uncertainty principle.
Researchers aim to correct quantum errors at super-cold temperatures instead of room temperature
Professor Mikko Möttönen has received a three-year grant from the Jane and Aatos Erkko Foundation to correct quantum errors. His research group is developing a solution that will allow microwave pulses to be kept at a temperature of millikelvin, or -273 degrees.
We are now hiring for the new 1.5-M€ project Autonomous Quantum Processor! If you are an exceptionally successful student (GPA >4.5/5.0) or have a PhD on cQED, send your cover letter and CV (including your GPAs) to Mikko by email at mikko.mottonen@aalto.fi. We will hire as soon as we can find amazing candidates.

We have a major effort on experimental quantum physics with superconducting circuits, but we also carry out computational and theoretical work down to fundamental quantum mechanics. Currently, we focus on control and readout techniques for superconducting qubits and on the implementation of on-demand dissipation in quantum circuits to study the related dynamics of open quantum systems.
We also develop ultrasensitive microwave detectors and on-chip components for controlling microwave photons, single-electron pumps based on silicon quantum dots, and quantum knots and monopoles in Bose-Einstein condensates. We are also proud to have given birth to a leading European quantum-computer company . Recently, we jointly developed with IQM an open-source software, KQCircuits, to design superconducting quantum processors, making our tools available for the entire quantum community (more information ).
Two Postdocs in superconducting qubits and millikelvin electronics
Did you recently get your PhD in circuit quantum electrodynamics (cQED) and are now looking into taking the full potential of your skills into use for making new scientific discoveries?
We are now looking for two Postdoctoral Researchers to join our development of improved superconduting qubits and millikelvin electronics which will be integrated to form an autonomous superconducting quantum processor at Aalto University’s Quantum Coputing and Devices (QCD) group at the Department of Applied Physics. In this position you have a chance to make history by demonstrating some of the first experiments of the future quantum-computer technology that is orders of magnitude more efficient than existing quantum processors. Join us in shaping the future!
Please go to find more information about the application process.

Bose-Einstein condensation (BEC) is a manifestation of macroscopic occupation of a single quantum state.
We develop components and methodology in the rapidly growing field of quantum computing, especially in the framework of circuit quantum electrodynamics (cQED).
QCD's activities cover theoretical and computational problems in quantum information science as well as experimental realizations of quantum devices.
Our rigorous long term goal is to find a high-yield (100 pA) and metrologically accurate (10 ppb uncertainty) current source which could be used to redefine the unit of electric current, the ampere.
