  A primary requirement for a robust and unconditionally secure quantum network
is the establishment of quantum nonlocal correlations over a realistic channel.
While loophole-free tests of Bell nonlocality allow for entanglement
certification in such a device-independent setting, they are extremely
sensitive to loss and noise, which naturally arise in any practical
communication scenario. Quantum steering relaxes the strict technological
constraints of Bell nonlocality by re-framing it in an asymmetric manner, thus
providing the basis for one-sided device-independent quantum networks that can
operate under realistic conditions. Here we introduce a noise-robust and
loss-tolerant test of quantum steering designed for single detector
measurements that harnesses the advantages of high-dimensional entanglement. We
showcase the improvements over qubit-based systems by experimentally
demonstrating detection loophole-free quantum steering in 53 dimensions through
simultaneous loss and noise conditions corresponding to 14.2 dB loss equivalent
to 79 km of telecommunication fibre, and 36% of white noise. We go on to show
how the use of high dimensions counter-intuitively leads to a dramatic
reduction in total measurement time, enabling a quantum steering violation
almost two orders of magnitude faster obtained by simply doubling the Hilbert
space dimension. By surpassing the constraints imposed upon the
device-independent distribution of entanglement, our loss-tolerant,
noise-robust, and resource-efficient demonstration of quantum steering proves
itself a critical ingredient for making device-independent quantum
communication over long distances a reality.
