Results in brief
Fully integrated and CMOS compatible, nanoscale Quantum enhanced magnetic SENSors for scalable submiliHertz, room temperature Nuclear Magnetic Resonance spectroscopy
1) What is the problem being addressed? The goal of the QSENS-NMR is to address the main challenges that prevent diamond material to scale up thousands of quantum sensors on a single chip. These mainly consider challenging and very expensive waveguide nanofabrication which is not compatible with the standard semiconductor industry. In this project we plant to use Silicon Carbide material as an alternative to diamond quantum sensors as it enables us to fabricate scalable, low cost quantum enhanced magnetometers integrated on a optical microchip using standard lithography techniques. 2) Why is it important for society? The successful realization would demonstrate the feasibility to integrate quantum sensors into a optical chip to reach low cost and scalable commercial devices which can be used for NMR sensing of biological samples. 3) What are the overall objectives? The goal of QSENS-NMR is to fabricate a single Silicon Carbide waveguide to demonstrate its fabrication feasibility and to perform quantum sensing experiments with implanted color centers.

Project objective
Quantum enhanced magnetometers (QEM) based on nitrogen vacancy centres in diamond provide nanoscale spatial resolution and single atom sensitivity that can achieve magneto-optical imaging, thermometry and Nuclear Magnetic Resonance (NMR) spectroscopy of individual molecules. These have implications in various areas of fundamental science, biomedicine and information storage. One goal of QSENS-NMR is to solve the main challenges which prevent diamond to integrate and scale up thousands of QEM's on a single chip. These consider: challenging diamond waveguide fabrication, incompatibility with the Complementary-Metal-Oxide-Semiconductor (CMOS) industry, scalability and commercialisation limitation given by the expensive, time consuming material growth and wafer size of diamond. QSENS-NMR aims to solve these issues by utilising Silicon Vacancy (SiV) defects in 4H-Silicon carbide (4H-SiC) material. Thanks to wafer bonding pieces from 6 inch 4H-SiC and Silicon Dioxide on Silicon wafers, QSENS-NMR will demonstrate waveguide fabrication in a CMOS compatible manner where shallow SiV defects will be implanted using scalable Focus Ion Beam. In such configuration, light can be easily coupled to simultaneously excite multiple defects. Additional fabrication of gold contacts will demonstrate the first on chip spin control and photoelectrical spin readout (PDMR) of single colour centers in SiC. The second goal of QSENS-NMR is to utilise the opportunity to manipulate and measure spin states in order to demonstrate the first submiliHertz NMR spectroscopy with SiC colour centres. By integrating simple, microfluidic channels, multiple samples of water can be delivered to various spatial locations of the chip where high resolution NMR measurements will be achieved using the Quantum Homodyne technique. QSENS-NMR thus paves the way to one day possibly scale up to thousands of NMR sensors on a single chip which can be used as a scalable diagnostic tool for cancer or viral research.
