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.
Singapore hosts optimistic ending to Bloomberg quantum documentary
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. “On the gleaming streets of Singapore, the quantum revolution has found fertile ground” said the show’s host, Hannah Fry, Professor in the Mathematics of Cities at University College London, UK.
Singapore research organisations and Quantinuum signed a Memorandum of Understanding enabling access to Quantinuum's advanced quantum computer, and to explore and collaborate on quantum computing use cases.
CQT researchers have found a way to make their circuit quantum electrodynamics (cQED) setup tunable. The key addition is a tiny handmade structure that can direct magnetic fields like water through a hose.
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.
