Quantum Processors, Computation & Simulation

The promise that quantum computers can tackle problems beyond the reach of today’s most powerful supercomputers is driving research worldwide in universities and businesses. At CQT, we work on a broad array of research problems in quantum computing and simulation. Our team includes computer scientists designing quantum algorithms, theorists working on approaches to error correction and experimentalists developing quantum hardware. We host experiments for analogue quantum simulation with ultracold atoms, ions and molecules.

CQT is also a founding member of Singapore’s National Quantum Computing Hub. The hub pools expertise and resources from CQT, A*STAR’s Institute of High Performance Computing (IHPC) and the National Supercomputing Centre (NSCC) Singapore to develop quantum computing capabilities and explore applications through industry collaborations. CQT is leading the National Quantum Processor Initiative launched under Singapore’s National Quantum Strategy in 2024 to develop capabilities to build a quantum processor with trapped ions or neutral atoms and support projects in photonics and control electronics.
