Summary
Through its phenomenal ability to image soft tissues, magnetic resonance imaging (MRI) has revolutionized both clinical medicine and research biomedicine. Nowadays, MRI scanners used clinically have spatial resolutions in the range of 0.5 mm. This enables identification and monitoring of disease processes throughout the body and visualization of minute brain structures. Magnetic resonance microscopy (MRM) brings the resolution down to the micron scale, so that cells and parts of cells can be seen. Using ultrasensitive silicon nano-wired mechanical resonators, we are working to distinguish small ensembles of nuclear and electron spins. In doing so, we are striving to bring MR down to the nanometer scale, allowing imaging of single viral particles. Subsequently, extending the approach to the Angstrom scale, our goal is to demonstrate MR imaging of individual protein molecules.

Quantum State Tomography with Machine Learning
Summary An important challenge in building a quantum computer is quantifying the level of control obtained in the preparation of a quantum state. The state of a quantum device is characterized from experimental measurements, using a procedure known as tomography. Exact tomography requires a vast amount of computer resources, making it prohibitive for quantum […]

Quantum Light Sources Based on Deterministic Photon Subtraction
Summary This project develops new sources of light that utilize quantum entanglement to enhance imaging resolution and detection. We aim to go beyond simple photon pairs and advance our understanding and control of new quantum states of light. Our approach uses deterministic single-photon subtraction (removing of a specific photon from a pulse of light) […]

On-Chip Microwave-Optical Quantum Interface
Summary In this project we develop a quantum interface between microwave and optical photons as a key enabling technology of a hybrid quantum network. In such a network, the robust optical photons carry quantum information through optical fibres over long distances, while superconducting microwave circuits protected from thermal photon noise by the low temperature […]
