A series of quantum physics experiments and theoretical papers now suggest that heat can flow spontaneously from a cold object to a hot one, provided the right quantum conditions are in place. This ...

A number of experiments have been proposed to generate and witness gravitational entanglement, but Aziz and Howl’s work suggests that the presence of gravitational entanglement is not a ‘smoking gun’ ...
