| contents | We show the targeted phase-manipulation of an entangled photonic Bell state via non-inertial motion. To this end, we place a very compact laboratory, consisting of a SPDC source and a Sagnac interferometer, on a rotating platform (non-inertial reference frame). The photon pairs of a $\ketϕ$-state are in a superposition of co- and counter-rotation. The phase of the $\ketϕ$-state is linearly dependent on the angular velocity of the rotating platform due to the Sagnac effect. We measure the visibility and certify entanglement with the Bell-CHSH parameter $S$. Additionally, we conduct a partial quantum state tomography on the Bell states in a non-inertial environment. Our experiment showcases the unitary transformation of an entangled state via non-inertial motion and constitutes not only a switch between a $\ket{ϕ^{-}}$-state and a $\ket{ϕ^{+}}$-state but also a further experiment at the interplay of non-inertial motion and quantum physics. |
