CQT researchers land on a magic wavelength for scaling atomic arraysThe group of Principal Investigator Loh Huanqian has become the first to use a class of ‘magic wavelengths’ for atom-trapping first predicted to exist over a decade ago. They used D1 magic wavelength optical tweezers to scale up their atom array numbers to an order of magnitude larger than was possible before. These findings are reported in Physical Review Research. |

Researchers propose tool to extract better performance from noisy quantum computersCQT PhD graduates Tobias Haug and Kishor Bharti and their collaborator demonstrate a tool that measures the power of parametrised quantum circuits, a building block of algorithms for quantum computers. The new approach could pave the way for improved circuit design. Better circuits could help extract better performance overall. |
Writers stand to win prizes of up to $1,500 for short stories that draw inspiration from topics in quantum physics
Working on time-space trade-offs in quantum computing, PhD student Debbie Lim is eager to learn and discover new knowledge in quantum computer science.

Popular Q Camp materials shared online for school studentsIn June, CQT hosted a virtual version of Q Camp, its annual outreach camp for Singapore school students, after COVID-19 made events on the university campus impossible. The camp was fully subscribed, with almost 40 students from 11 different schools participating. To open access to more students and learners in other countries, a big chunk of camp materials has now been posted online. |
