Last February 15 Dr. Guilherme d´ Oliveira Martins, Administrator of the Fundação Calouste Gulbenkian, was in IT in Lisbon for the inauguration of the new QuTe Lab – Quantum Technologies Laboratory of the PIQT - Physics of Information and Quantum Technologies Group.
“Among other things, this laboratory is investigating free space quantum communications”, says Yasser Omar, Professor in the Department of Mathematics of IST and the coordinator of PIQT.
The experiments in the QuTe Lab are being developed by Prof. Manfred Niehus and IST undergraduate student José Jesus, a member of the Gulbenkian Programme New Talents in Quantum Technologies, a innovative program that was developed jointly between PIQT and the Serviço de Bolsas da Gulbenkian. These scholarships are designed to support undergraduate and masters students (in Physics, Mathematics, Electrical Engineering, Computer Engineering, among others) from Portuguese universities in the development of a small study and research project in quantum computing, quantum communications, metrology and quantum sensors, or other related areas. Students don´t need to have previous knowledge in Physics of Quantum Technologies since the program guarantees they will receive all the necessary training.
A cover article of the January 2019 issue of Nature Photonics, a highly-referenced journal in the field of photonics, describes a chip-scale Brillouin laser capable of emitting light with a fundamental linewidth of less than 1 Hz - narrow enough to move demanding scientific applications to the chip scale.
Cátia Pinho a fellow researcher from IT in Aveiro contributed to this work in the scope of a scientific research mission under her Ph.D. studies at the Optical Communications and Photonic Integration (OCPI) group from the University of California, Santa Barbara (UCSB) advised by Daniel Blumenthal, Professor of Department of Electrical and Computer Engineering at UCSB.
Spectrally pure lasers, the heart of precision high-end scientific and commercial applications, are poised to make the leap from the laboratory to integrated circuits. Translating this performance to integrated photonics will dramatically reduce cost and footprint for applications such as ultrahigh capacity fibre and data centre networks, atomic clocks and sensing. The demonstrated sub-hertz fundamental linewidth Brillouin laser translates advantages of non-integrated designs to the chip scale. Single- and multiple-frequency output operation provides a versatile low phase-noise solution, highlighted by the demonstration of an optical gyroscope and a low-phase-noise photonic oscillator.
Cátia Pinho is currently finalizing her Ph.D. from the MAP-tele Doctoral Programme in Telecommunications at the University of Aveiro, supervised by António Teixeira and Mário Lima, Professors of the Department of Electronics, Telecommunications and Informatics (DETI) of University of Aveiro and senior researchers from IT.
