Twisted photons can be used as alphabets to encode information beyond one bit per single
photon. This ability offers great potential for quantum information tasks, as well as for the …

Whenever a quantum system undergoes a cyclic evolution governed by a slow change of
parameters, it acquires a phase factor: the geometric phase. Its most common formulations …

The robust generation and propagation of multiphoton quantum states are crucial for
applications in quantum information, computing, and communications. Although photons are …

Topological photonics is a rapidly emerging field of research in which geometrical and
