Engineered Quantum Systems (Linneqs)

We have reached a new era where fundamental quantum physics meets with nanotechnology and electronics. Exciting opportunities open up when we can engineer quantum systems at the interface between quantum physics, computer science, electronics, and material science. We propose research in three areas.

Qubits:
The research long-term goal is to develop quantum computers, which are predicted to perform some computational tasks much faster than ordinary computers. This research also addresses fundamentally important issues in quantum mechanics such as entanglement, decoherence and quantum measurement.

Quantum transport:
New nanotechnologies allows study of processes in quantum devices for qubit applications and ultra sensitive detectors. the researchers in particular study 3 specific systems, where they recently have been very successful: single electron counting, single molecular devices, and intrinsic Josephson junctions.

Enabling technologies:
The researchers aim at developing 1) a classical interface to multi qubit circuits using RSFQ logic, 2) a scanning SET studying charge distributions on surfaces, to understand qubit decoherence and 1/f noise in devices. 3) With a new technology they can isolate and study the tunnel barriers at the atomic level, which helps to improve our junctions.
