<div>The concept of mode division multiplexing also known as space division multiplexing was introduced as an alternative to combat the approaching capacity crunch in single mode fibers. Just like single mode fibers, space division multiplexed fibers will experience non-linearity at a different level and studies have shown that some linear effects can be beneficial in combating the nonlinear interference. This study aims to identify the benefits accrued when these linear effects are implemented by exploring the already existing models defined in the literature.</div>

Abstract Single photon or biphoton states propagating in optical bers or in free space are affected by random perturbations or imperfections along optical bers or free space that disturb the information encoded in such states and accordingly quantum key distribution is prevented. We propose three different systems for autocompensating such random perturbations and imperfections when a measurement-device-independent protocol is used. These systems correspond to different optical bers intended for space division multiplexing and supporting collinear modes, polarization modes or codirectional modes such as few-mode optical bers and multicore optical bers. Accordingly, we propose different Bell-states measurement devices. Finally, these types of optical bers allow the use of several transmission channels what compensates the reduction of the bit rate due to losses.

These systems correspond to different optical fibers intended for space division multiplexing and supporting collinear modes, polarization modes or codirectional modes such as few-mode optical fibers and multicore optical fibers. Accordingly, we propose different Bell-states measurement devices located at Charlie system and present simulations that confirm the importance of autocompensation. Moreover, these types of optical fibers allow the use of several transmission channels, which compensates the reduction of the bit rate due to losses.
