Limits set on quantum radar’s ability to hide itself
How well can you see without been seen? CQT’s Mile Gu and his colleagues tackle that queston in research on the performance of quantum radars published in Physical Review Letters. They calculate from theoretical models how to optimise a quantum radar to detect a remote object without the signals it sends being detectable.
Meet a CQTian: Guo Naixu
Guo Naixu is currently a a third-year PhD student in Patrick Rebentrost's group working on on quantum algorithms and quantum learning theory. Naixu is also a guqin player. His interest in this instrument started as an undergraduate in Japan. He says, "It was very lucky that I found out there is a great Japanese guqin master, Muka Fushimi, in Kyoto and he lived near my home. I directly knocked on his door and began this music journey. I quite enjoy this kind of fate."
Bloomberg Originals has released a documentary on quantum computing that travels to Singapore. The episode of The Future with Hannah Fry includes an interview with CQT's Alexander Ling and scenes from CQT labs.
CQT Fellow Di was recently commended in the MIT Technology Review Innovators Under 35 (TR35) Asia Pacific list for his work in integrated quantum photonics. Congratulations!
Algorithm settles financial transactions with fewer qubits
Millions of transactions are executed in the financial markets every day, and finding an optimal way to settle them is a computationally heavy task. In a paper published in EPJ Quantum Technology, CQT Principal Investigator Dimitris Angelakis and his team report that a qubit-efficient optimisation algorithm they created in earlier work can tackle the financial transaction settlement problem.
