# Quantum gravitational decoherence of light and matter

@article{Oniga2016QuantumGD, title={Quantum gravitational decoherence of light and matter}, author={Teodora Oniga and Charles H.-T. Wang}, journal={Physical Review D}, year={2016}, volume={93}, pages={044027} }

Real world quantum systems are open to perpetual influence from the wider environment. Quantum gravitational fluctuations provide a most fundamental source of the environmental influence through their universal interactions with all forms of energy and matter causing decoherence. This may have subtle implications on precision laboratory experiments and astronomical observations and could limit the ultimate capacities for quantum technologies prone to decoherence. To establish the essential… Expand
