Can Gravity Entangle Diamonds? A Quantum Quest

This white paper proposes an experiment to test if gravity is quantum by seeing if it can entangle two micron-sized diamonds in superposition. The experiment relies on embedding spins in the diamonds and using the Stern-Gerlach effect to create the superposition, with measurements of the spins then used to detect entanglement.

Identified Weaknesses

Technological Challenges

Creating and maintaining the required quantum superpositions for macroscopic objects like diamonds poses huge technological hurdles, such as isolating them from noise and decoherence.

Minimizing EM Interactions

Since gravity is much weaker than electromagnetic forces, even tiny electromagnetic interactions could swamp the gravitational effect and obscure the results. Precise shielding and control is crucial.

Theoretical Uncertainties

While the protocol is based on plausible assumptions, there are open theoretical questions regarding the validity of the assumptions and the interpretation of potential results.

Experimental Complexity

This experiment is extremely ambitious, demanding cutting-edge technologies, extensive engineering, and a large, collaborative effort. Many things could go wrong.

Rating Explanation

The paper proposes a compelling experiment to test a fundamental question about the nature of gravity. The methodology is sound, although achieving the required level of experimental control presents formidable challenges. It represents a significant push in the field, with potential to resolve a long-standing theoretical debate. Therefore, a rating of 4 is justified despite the experimental hurdles and theoretical uncertainties involved.
