The primary goal of QuCoM is to demonstrate the proof of concept (TRL 1) for a levitated acceleration sensor capable of detecting gravity in the quantum-controlled regime, especially for small masses. To achieve this objective, we aim to explore the interplay between quantum mechanics and gravity within a parameter range conducive to cost-effective tabletop experiments. Our approach involves suspending sub-millimetre particles in optical and magnetic traps, using them to detect gravitational forces in an unprecedented mass regime. Additionally, we will investigate quantum superpositions in which these masses exhibit delocalisation.
The project will address prominent theoretical proposals that combine quantum physics and gravity in unconventional ways, assessing their limits of validity and potentially constraining the values of their parameters. The consortium comprises two experimentalists, two theorists, and two SMEs, pooling their expertise to achieve the project’s objectives. Leveraging the experimental knowledge of consortium partners, QuCoM aims to go beyond by demonstrating two-mass gravity sensing and operating sensors in the quantum domain.
The theoretical aspects, including state preparation, control, and analysis schemes, are grounded in the expertise of our theory partners. High-tech SMEs within the QuCoM consortium will play a crucial role in optimising the experimental apparatus to meet the targeted objectives. This optimisation will position them to offer improved products, specifically sub-mK, low-vibration cryogenic equipment, to the market.
Furthermore, we will explore the feasibility of implementing our technology into a micro-satellite platform for space-based metrology and Earth exploration, utilising gravitational detection. This represents a direct technology impact and an innovation case for QuCoM.
