These feats reveal that, given the striking success of quantum mechanics, attributes such as 'particle' and 'wave' cannot sustain any higher epistemic meaning. Preparing a photon in a coherent ...

The Einstein equivalence principle (EEP) has a central role in the understanding of gravity and space–time. In its weak form, or weak equivalence principle (WEP), it directly implies equivalence ...

Quantum effects have been demonstrated on one of the largest scales ever, pushing the boundaries of the quantum world. A crystal of 10^16 atoms has been placed in a superposition of two quantum states ...
