About the Centre for Quantum Technologies (CQT) The Centre for Quantum Technologies (CQT) in Singapore brings together physicists, computer scientists and engineers to do basic research on quantum physics and to build devices based on quantum phenomena. Experts in this new discipline of quantum technologies are applying their discoveries in computing, communications, and sensing. CQT is hosted by the National University of Singapore. The Centre also has staff at the Agency for Science, Technology and Research, Nanyang Technological University, Singapore, and the Singapore University of Technology and Design. With some 200 staff and students, it offers a friendly and international work environment Learn more about CQT at https://www.cqt.sg/ Job Description The ultimate systematic performance of any ion clock is set by the quality of its trap and the thermal environment surrounding it. Cryogenic ion traps — operating at 4 K and below — eliminate blackbody radiation from the trap structure, reduce anomalous heating rates by orders of magnitude, and enable ultra-low-pressure conditions unachievable at room temperature. For Lu+, already an exceptional clock species, a cryogenic platform would unlock a systematic uncertainty budget at the 10-19 level and below. This postdoc offers a rare chance to design, build, and operate a next-generation cryogenic ion trap system from the ground up — an instrument-building challenge at the frontier of experimental physics.
