  • Combining on-chip photon-pair sources, two sets of linear integrated circuits for path entanglements and two path-to-orbital angular momentum converters, free-space-entangled orbital angular momentum photon pairs can be generated in high-dimensional vortex states, offering a high level of programmable dynamical reconfigurability.

  • A photonic anomalous Floquet insulator is emulated in a silicon photonic chip. Up to four-photon topologically protected entangled states are generated in a monolithically integrated emitter in ambient conditions through four-wave mixing on top of the edge modes of the insulator.

  • Qudit-based quantum devices can outperform qubit-based ones, but a programmable qudit-based quantum computing device is still missing. Here, the authors fill this gap using a programmable silicon photonic chip employing ququart-based encoding, showing the scaling advantages compared to the qubit counterpart.

  • Switching the magnetization of a ferromagnetic layer with a current induced spin-orbit torques requires the breaking symmetry, either via an in-plane magnetic field, or in the case of field-free switching via a device asymmetry. Here, Liang et al carefully control the Burgers vector of crystal dislocations to break the in-plane symmetry and allow for field-free switching of magnetization in a Pt/Co heterostructure.

  • A graph-theoretical programmable quantum photonic device composed of about 2,500 components is fabricated on a silicon substrate within a 12 mm × 15 mm footprint. It shows the generation, manipulation and certification of genuine multiphoton multidimensional entanglement, as well as the implementations of scattershot and Gaussian boson sampling.

  • Designing an efficient activation function for optical neural networks remains a challenge. Here, the authors demonstrate a modulator-detector-in-one graphene/silicon heterojunction ring resonators enabling on-chip reconfigurable activation function devices with phase activation capability for optical neural networks.

  • There has been substantial interest in using magnons for information processing. At low magnetic fields, many magnets can form complex domain structures. Here, Li et al study how magnons propagate in a ferrimagnet with domains, finding that the passage of magnons is remarkably insensitive to this complex domain landscape.

  • Evolution of accretion disk and corona during outbursts in black hole binary systems is still unclear. Here, the authors show spectral analysis of MAXI J1820+070 and propose a scenario of a dynamical corona to explain the evolution of the reflection fraction observed by Insight-HXMT.
