Photonic spatial quantum states are a subject of great interest for applications in communication. One important challenge has been how to dynamically generate these using only fiber-optical components. Here we propose and experimentally demonstrate an all-fiber system that can switch between any general transverse qubit state based on linearly polarized modes. Our platform is fast optical Sagnac interferometer combined with photonic lantern few-mode fibers. We show switching times modes the...
Wave-particle duality is one of the most notable and counterintuitive features quantum mechanics, illustrating that two incompatible observables cannot be measured simultaneously with arbitrary precision. In this work, we experimentally demonstrate equivalence wave-particle entropic uncertainty relations using orbital angular momentum (OAM) states light. Our experiment uses an innovative reconfigurable platform composed few-mode optical fibers photonic lanterns, showcasing versatility...
The orbital angular momentum (OAM) spatial degree of freedom light has been widely explored in many applications, including telecommunications, quantum information, and light-based micromanipulation. ability to separate distinguish between the different transverse modes is called mode sorting or demultiplexing, it essential recover encoded information such applications. An ideal d sorter should be able faithfully modes, with minimal losses, have outputs fast response times. All previous...
