UCPH (Denmark)

University of Copenhagen, UCPH - Denmark

The University of Copenhagen is a top ranked university in Denmark with more than 40,000 students and more than 11,000 scientific, technical, and administrative staff. Under sponsorship of the Danish National Research Foundation, the Center for Quantum Devices (QDev) was established in 2012 to investigate how to create, control, measure, and protect quantum coherence and entanglement in solid-state electronics.

Main tasks in MOS-QUITO:
  • UCPH will be involved in WP2-WP7.
  • UCPH will lead WP7 “Dissemination and exploitation”.
  • Focus on the implementation and benchmarking of QD spin qubits and singlet-triplet qubits in WP3 and two-qubit gates and multi-qubit readout in WP4.
  • Contribute to device fabrication in WP2, device modelling in WP5 (micromagnetic and electrostatic device simulations) and testing of multi-plexers and on-chip amplifiers in WP6.
Key persons related to the proposal at UCPH:

Charles Marcus is the Villum Kann Rasmussen Professor at the Niels Bohr Institute and Center Director of QDev. Before coming to Copenhagen in 2011, he also taught Physics at Stanford University and Harvard University. His research interests include neural networks, quantum chaos, mesoscopic physics, fractional quantum Hall systems, quantum information, spin qubits and topological quantum states in condensed matter.

Ferdinand Kuemmeth joined the Niels Bohr Institute as Associate Professor in 2012. His research at QDev focuses on practical quantum design and cryogenic electric manipulation and readout techniques, implemented in 2D electron gases and low-dimensional semiconductors such as silicon-germanium heterostructures, nanowires and GaAs quantum bits.

Prof. Charles Marcus and Prof. Ferdinand Kuemmeth have extensive research experience in low-temperature electronic techniques and the coherent control of solid-state quantum bits. Specifically, they currently receive funding from IARPA for developing GaAs-based multi-qubit devices as part of the “Multi-Qubit Coherent Operations (MQCO)” project, and for silicon-based quantum devices from the EU ICT program “Silicon platform in Quantum Spintronics (SiSPIN)”. Other funding sources include the Danish National Research Foundation, Villum Foundation, US agencies (IARPA, DARPA) and Microsoft.
