What we do
Topologically protected qubit
Quantum states are fragile and tend to decohere quickly: interaction with the environment alters the quantum state. The Qubit Research division focuses on the development of robust quantum devices: quantum bits that are intrinsically protected by the underlying physical principles. To this end we combine material science, theory, and novel device design. Our activities range from the study of fundamental physical principles to the fabrication of new qubit prototypes.
The current focus of our research is towards storing and manipulating quantum information using topologically protected qubits. In particular, we study superconducting/semiconducting systems hosting Majorana bound states. Our experimental focus lies on hybrid systems based on semiconductor nanowires and nanowire networks and two-dimensional semiconductor systems. These efforts are integrated with numerical device simulations.
With this joint effort we aim to develop the first qubit based on Majorana bound states, which is topologically protected against decoherence.
Bringing experts together
To this end, the Qubit Research division also has a strategic partnership with Microsoft. Our collaboration with Microsoft dates back to 2011. In 2017 we entered a new long-term collaboration and Microsoft has stepped up his investments and established a Microsoft Quantum Lab in Delft, headed by Prof. Leo Kouwenhoven. Together we form the largest focused effort in our field.
