  • A skyrmion is a topologically stable field configuration. A non-local skyrmion, which has been hitherto elusive in condensed-matter physics, is realized by using entangled photons with a non-trivial topology. The connection between the notions of topology and entanglement is investigated, revealing topological invariance even when entanglement is fragile.

  • High-dimensional quantum states allow for several advantages in quantum communication, but protocols such as teleportation require additional entangled photons as the dimension increases. Here, the authors show how to transport a high-dimensional quantum state from a bright coherent laser field to a single photon, using two entangled photons as the quantum channel.

  • A mooted advantage of high-dimensional states is their robustness to noise, yet their fragility in noisy channels has hindered their deployment. A demonstration shows how to exploit entanglement to restore quantum correlations lost in transmission.

  • The limited control of electrons by light has resulted in photonic-driven circuits lagging far behind their electronic counterparts. Now, a technique exploiting coherent control with structured light has been used to sculpt the spatial distribution of electric currents, ushering in vectorized optoelectronic control in semiconductors.
