Quantum Sensing & Metrology (QSM)

RESEARCH FOR REAL-WORLD IMPACT

Q.InC's Quantum Sensing and Metrology (QSM) pillar develops advanced quantum sensing technologies that translate into real-world application. By leveraging the principles of quantum mechanics, our sensors achieve unprecedented sensitivity that surpasses the limits of today’s technologies. This leap in capability is set to transform critical fields, such as biomedicine, defense, space, and fundamental physics.

Answering the unanswered

To answer fundamental questions about quantum physics and gravity, we need to measure large quantum systems with unprecedented accuracy. At Q.InC, we are developing precisely these capabilities, pushing the boundaries of quantum sensing to uncover weaker signals and finer details than ever before. We don’t just build sensors; we bridge the gap from lab to life. Our aim is to create robust devices that perform in real-world environments, establishing Singapore as a global leader in next-generation sensing and helping harness quantum phenomena for the technologies of tomorrow.

Making the invisible visible

Our quantum technologies make the invisible visible, revealing critical information hidden from conventional sensors. By accessing new parts of the light spectrum, we can develop methods to detect minute traces of explosives or identify early markers of disease in biological samples. Sensing subtle shifts in Earth’s gravitational and electromagnetic fields also opens new possibilities. This capability enables ultra-precise navigation in GPS-denied environments and allows for the detection and identification of distant drones. Furthermore, our enhanced sensitivity allows us to peer deep beneath the ocean's surface or the Earth’s crust to uncover hidden structures, submarines, or natural resources.

OUR WORK

We harness quantum phenomena like superposition and entanglement to engineer sensors with exceptional sensitivity and precision. Our diverse portfolio includes deployable squeezed light sensors, sensitive atomic vapor sensors, quantum levitated sensors, and novel quantum imaging and spectroscopy techniques. In parallel, we develop key enabling technologies for quantum networks, such as advanced quantum light sources and realistic simulations.

Our research advances a wide range of sensing platforms to solve key problems:

Sensing minute signals

Atomic vapour cells, which employ clouds of atoms whose quantum spins react to incredibly small fluctuations in magnetic fields, for extreme sensitivity

Overcome environmental limitations

Magnetic and superconducting levitation to isolate systems from environmental noise, facilitating the utilisation of quantum phenomena in noisy, real-world environments

Achieving classically impossible precision

Optical techniques such as quantum imaging, spectroscopy, squeezed light and optical atomic clocks, to measure systems with precision that is classically impossible

Validate real-world quantum advantage

Novel concepts in quantum metrology to rigorously quantify "quantum advantage," identifying practical use cases where quantum sensors deliver a decisive edge over state-of-the-art classical technologies
