Delta.g, a UK-based company, has won the 2025 qBIG prize awarded by the Institute of Physics (IOP) for its gravity sensors.
The company specializes in making quantum sensors that measure the local gravity gradient using atom interferometry technology.
The qBIG prize, sponsored by Quantum Exponential, includes a £10,000 cash prize, mentoring, and business support for Delta.g.
The IOP commended two runners-up, Neuranics and Smith Optical, for their innovative quantum sensor and augmented reality display technologies, respectively.
