Abstract: Orbital angular momentum (OAM) states of photons span a high-dimensional Hilbert space, and by using it, higher information capacity and enhanced security can be achieved for both classical ...

Orbital-angular-momentum (OAM) multiplexing optical wireless communications (OWCs) enable to provide ultralarge capacity, high-speed, low-latency, low-energy consumption, secure, and reliable ...

After the sharp rise in 2024, which saw the market cap cross $3 trillion, attention is now turning to whether that momentum is sustainable and what ... The rollback of SEC guidelines such as SAB 121 ...
