A graph-theoretical approach to spin-polarised quantum walks in chiral environment — •Saba Arshad¹, Sibylle Gemming¹, and Shahid Iqbal² — ¹TU Chemnitz, Chemnitz, Germany — ²NUST, Islamabad, Pakistan

Exploring the model where a particle or system of particles moves between neighboring nodes couple with autonomous spins on the edges, leading to the propagation of entanglement. The work highlights how entanglement, along with spin oscillations and relaxation dynamics, offers significant advantages while transmitting directed quantum information through the quantum walks, providing faster quantum computations. This approach establishes a connection between spin dynamics and quantum computation, with potential applications in cryptography, quantum key distribution, super-dense coding, teleportation, and quantum computing, leveraging entangled states for secure and efficient information processing.
