Photonic quantum technologies represent a promising platform for several applications,
ranging from long-distance communications to the simulation of complex phenomena …

In recent years, quantum computing has made significant strides, particularly in light-based
technology. The introduction of quantum photonic chips has ushered in an era marked by …

Conventionally, unconditional information security has been studied by quantum
cryptography although the assumption of an omnipotent eavesdropper is too strict for some …

With the vastly growing need for secure communication, quantum key distribution (QKD) has
been developed to provide high security for communications against potential attacks from …

One of the main challenges in quantum technologies is the ability to control individual
quantum systems. This task becomes increasingly difficult as the dimension of the system …

Quantum key distribution (QKD) assures the theoretical information security from the
physical layer by safely distributing true random numbers to the communication parties as …

Quantum cryptography is the study of unconditional information security against an all-
powerful eavesdropper in secret key distillation. However, the assumption of an omnipotent …

Traditionally, the study of quantum key distribution (QKD) assumes an omnipotent
eavesdropper that is only limited by the laws of physics. However, this is not the case for …

We propose an improved quantum key distribution (QKD) protocol based on orbital angular
momentum (OAM) entangled states. Three Lucas-valued OAM entangled photons are …

Drawing inspiration from the Fibonacci sequence and its complementary Lucas sequence,
this paper introduces an innovative encryption and decryption algorithm tailored for multi …
