“This quantum calligraphy allows deterministic placement and real time design of arbitrary patterns of SPEs for facile coupling with photonic waveguides, cavities and plasmonic structures,” said Berend Jonker, Ph.D., senior scientist and principal investigator. “Our results also indicate that a nano-imprinting approach will be effective in creating large arrays or patterns of quantum emitters for wafer scale manufacturing of quantum photonic systems.”
Dr. Matthew Rosenberger, lead author of the study, points out the importance of this discovery stating, “In addition to enabling versatile placement of SPEs, these results present a general methodology for imparting strain into two dimensional (2D) materials with nanometer-scale precision, providing an invaluable tool for further investigations and future applications of strain engineering of 2D devices.”
The results of this study pave the way for the use of 2D materials as solid state hosts for single photon emitters in applications relevant to the Department of Defense (DoD) mission, such as secure communications, sensing and quantum computation. Such applications enable communication between distant DoD forces which is not vulnerable to eavesdropping or decryption, an essential requirement to insure the safety of the warfighter.
Quantum computation on a chip provides onboard capability to rapidly analyze very large data sets acquired by sensor arrays, so that the entire data set does not have to be transmitted, reducing bandwidth requirements. The research results are reported in the January 2019 ACS Nano (DOI: 10.1021/acsnano.8b08730).
