Focus Areas
UB Quantum Institute research studies a wide range of aspects of distributed quantum information processing including computing, communication and sensing.
These efforts contribute to the general studies of quantum information science and technology (QIST) and help lay the foundation for applications that are aligned with the ambitions of the SUNY STRIVE Task force, national priorities and industry stakeholders.
Focusing on materials and device studies relevant for quantum information processing.
Topics of interest at present include:
- Materials studies that can enable superior quantum coherence or control
- Novel materials that may enable new functionalities
- Quantum coherent phenomena in heterogeneous materials systems
Current Projects:
- Study of electrically tunable on-demand single-photon emitters based on 2D hBN/TMDC materials (PIs: Huamin Li, Changjiang Liu, Vasili Perebeinos, and Dusan Sarenac)
- Magnons for quantum transduction (PIs: Igor Zutic, Jamir Marino)
- Improving quality of Josephson junctions based on Niobium nitride (PIs: Baishakhi Mazumder, Kristofer Reyes)
Realizing scalable quantum platforms that are relevant for communication, computing, sensing and quantum simulations:
- Scientific and engineering problems that can benefit from quantum coherent technologies and algorithms and technical approaches that can enable such applications of QIST
- Developing a software framework for large-scale fault-tolerant quantum systems, such as a distributed quantum computer, its quantum error correction, and a quantum network)
- Studies of hybrid quantum systems for scalable QIST:
- Working on photon-enabled quantum information processing with a focus on seeking novel protocols of light-mediated operations among material qubits
Studying quantum sensing and its application in biology, chemistry and biomedical research.
Quantum metrology, sensing and imaging with non-classical states of light (e.g., entangled photon pairs, Fock states or squeezed light):
- Yields higher signal-to-noise ratio (SNR), translating to higher sensitivity, due to surpassing the quantum shot noise limit of coherent light sources. Moreover, the principles and foundations of quantum metrology allow for low-power and high-sensitivity operation, which is critical for healthcare and space applications
Concentrating on quantum materials and quantum photonics devices that enable quantum sensing and quantum imaging platforms.
Research includes:
- Leverage unique physico-chemical properties of Si-compatible 2D materials (hBN, TMDCs, MXenes, MBenes) in defect engineering for single-photon emitters
- Fabricating on-chip quantum light sources, detectors, and interconnects
- Design and fabricate chiral dielectric metasurfaces, topological photonic crystal wave guiding networks, and defect-engineered functional materials for seamless on-chip integration and signal transduction
- Advance quantum-correlated linear, two-photon, spontaneous and stimulated Raman and tip-enhanced microscopies to simultaneously achieve unprecedented sensitivity, resolution, chemical specificity and data acquisition speed with a primary focus on application to biomedical research
