Integrated Quantum Photonics


To develop critical device components for integrated quantum photonics platforms towards developing a fully integrated photonics quantum computer. This is divided into three areas: 

  • Thin-film lithium niobate platform
  • Nanophotonic devices for generating and controlling quantum light
  • Integrated photodetectors

Quantum Sensing and Metrology


To develop quantum technologies for biomedical and physical sensing, which includes:

  • Quantum Metrology with Undetected Photons (QMIP)
  • Precise phase measurements via quantum interferometry
Infrared metrology finds wide application ranging from gas sensing for industrial safety purposes, biomedical diagnostic imaging, food safety and more. This is due to fingerprint absorption properties of numerous molecules in the infrared region.

Here, we develop infrared metrological technologies, such as spectroscopy and hyperspectral imaging, based on quantum mechanical principles of entanglement and interference, specifically a phenomenon called ‘induced coherence without induced emission’. As a result, material information, in the infrared, are measured via visible light detection. This enables the use of low-cost, non-export-controlled, well-established visible light sources and detectors, thus leading to significant cost-savings and operational flexibility.

Ultra-sensitive magnetometers can be used in diverse applications ranging from brain/heart imaging to mineral and geomagnetic surveys. By using ultra-sensitive magnetometers, it is also possible to envision performing nuclear magnetic resonance (NMR) or magnetic resonance imaging (MRI) without using large and expensive magnets, which can significantly decrease the cost of NMR and MRI machines while increasing their portability. Such magnetometers can also be used to probe the nuclear quadrupole resonance (NQR) of various chemicals, which can be useful for pharmaceutical control applications, as well as in explosives or narcotics detection.

Here, we are developing alkali atomic magnetometers as the next-generation of ultra-sensitive magnetometers that are capable of reaching fT/sqrt(Hz) sensitivities without needing the cryogenic cooling that current state-of-the-art Superconducting Quantum Interference Devices (SQUIDs) require. This translates to significant cost-savings and flexibility in operation, which can not only enhance many of the applications listed above, but also unlock heretofore unexplored applications.

Quantum Materials and Devices


To realise high quality device-ready 2D semiconductor material stack with dielectric encapsulation for valley-pseudospin qubits, and hence develop qubit gates in 2D transition metal dichalcogenides (TMDCs), e.g., MoS2, WS2.

We are interested in the development of quantum materials and devices towards a scalable quantum computer. Some of the key challenges are to obtain a long coherence time, low error rate and a scalable platform. We exploit the unique electrical and optical properties in atomically thin two-dimensional transition metal chalcogenides (TMDCs), such as spin-valley interlocking, spin-orbit coupling and potential compatibility with standard CMOS processes to tackle these challenges.
