Abstract: Einstein's equivalence principle, which states that all physical laws take their special-relativistic form in any local inertial frame, is the core of general relativity. How this principle extends to the quantum framework is still a matter of debate among physicists. Tests of the principle are performed by default on particles with defined masses, in classical reference frames, and in well-defined spacetimes. I will formulate extensions of the principle to quantum systems in superpositons of energies (i.e., masses), for quantum reference frames (the reference frames that can be attached to a freely falling quantum particles), and non-classical spacetimes. I will argue that these extensions of the principle have not yet been tested in experiments to date.
