- Acceleration causes asymmetry in shared entanglement affecting protocol performance
- Extra LOCC steps can mitigate asymmetry-induced losses
- Relativistic effects extend beyond simple entanglement degradation

## Abstract

We investigate how relativistic acceleration of the observers can affect the performance of the quantum teleportation and dense coding for continuous variable states of localized wavepackets. Such protocols are typically optimized for symmetric resources prepared in an inertial frame of reference. A mismatch of the sender's and the receiver's accelerations can introduce asymmetry to the shared entanglement, which has an effect on the efficiency of the protocol that goes beyond entanglement degradation due to acceleration. We show how these asymmetry losses can be reduced by an extra LOCC step in the protocols.
