New quantum technology projects receive funding boost
Monday, March 4, 2019
Detecting chemicals in water with quantum sensors and developing new materials to enable topological quantum computing are among the goals of eight projects recently supported by the Quantum Quest Seed Fund (QQSF).
Awarded by Transformative Quantum Technologies (TQT), the fund encourages new ideas and uncovers new opportunities from diverse fields outside the scope of researchers working day-to-day with quantum devices, and supports TQT’s mission to accelerate the development and deployment of impactful quantum devices. To date, 22 projects have been awarded, and $2.2 million in funding distributed.
Quantum sensors to keep our water clean
Kevin Musselman, assistant professor in the Faculty of Engineering, is leading a project to develop next-generation chemical sensors. He aims to create new functionalized quantum dots of 2D materials for the sensing of four highly-toxic heavy metal pollutants: arsenic, cadmium, lead, and mercury.
“The zero-dimensional nature of quantum dots leads to unique properties that make them very promising for fluorescence-based chemical sensing. These properties include strong absorption, strong fluorescence, solubility, and stability,” said Musselman. His proposed multimodal sensing platform can be used in the field, overcoming a barrier of existing techniques that are currently not suitable for on-site analysis of water contamination.
Enabling topological qubits for quantum computing
An ideal quantum computing system allows for easy coupling of qubits and strong decoupling of qubits from noise and dissipation. “However, in nearly all proposed qubit systems, these two attributes are often found in inverse relationship to each other,” explained funding recipient Zbigniew Wasilewski, Institute for Quantum Computing (IQC) associate and professor in the Department of Electrical and Computer Engineering.
In collaboration with IQC researchers Jonathan Baugh and François Sfigakis, Wasilewski is developing materials for Majorana-based topologically protected qubits on a computing platform that can be readily scaled to logical qubit devices.
