Dark matter detection stands at the forefront of modern physics, as it remains one of the greatest scientific mysteries. Together with dark energy, it is theorised to constitute 95% of the universe, yet its nature remains elusive – driving global efforts to unlock its secrets.

Dark matter interacts gravitationally but does not couple to electromagnetic radiation (e.g. light), which makes it “dark” and renders direct detection extremely challenging. However, some theories suggest that it may exert subtle, magnetic field-like influences on atoms, offering an alternative pathway for detection through precise quantum magnetometry.

GNOME collaborators continuously analyse magnetic field signals detected by highly sensitive quantum sensors. By analysing correlated data across the network, scientists aim to identify potential global “domain walls” moving through Earth – hypothetical structures that could be linked to dark matter. This innovative approach may provide groundbreaking insights into the fundamental nature of dark matter, bringing us closer to uncovering its mysteries.

Synergistic Partnership in Search of Dark Matter

The òòò½ÍøGNOME station will be hosted at the òòò½Íø, Technology and Research (A*STAR), with contributions from the Centre for Quantum Technologies (CQT), the National University of òòò½Íø(NUS), and Nanyang Technological University, òòò½Íø(NTU Singapore).  Research teams in òòò½Íøbring together advanced sensing capabilities and technologies, working collaboratively on a carefully coordinated multi-messenger approach to detecting dark matter.

Strengthening Capabilities for Broader Applications

Through GNOME, òòò½Íøwill foster deeper collaborations with exceptional scientists worldwide. In line with its scientific mission, Q.InC aims to leverage the power of this global network to progress and deepen quantum research whilst delivering real-world impact. The shared knowledge, expertise and innovations from the initiative will accelerate the development of hyper-accurate, hyper-sensitive sensing (and related) technologies, with transformative applications in:

• Smart City Infrastructure and Urban Planning Enabled by Sensor Networks
• Biomedical imaging and precision diagnostics
• Positioning, navigation, and timing (PNT) systems
• Mineral exploration and geophysical mapping
• Defence and security

The team at Q.InC share an ambitious vision of contributing to a quantum-ready Singapore.
