Quantum Computing and Communication (Cryptography) Integration

Quantum Computing and Communication (Cryptography) Integration

Although quantum cryptography offers extremely high security, it still faces two major challenges: transmission distance and quantum key rate. To improve this technology, we must employ powerful theoretical and computational tools—one of which is tensor networks, particularly the Multi-scale Entanglement Renormalization Ansatz (MERA) architecture. MERA provides an efficient structure for the optimal encoding of quantum states of matter, especially in critical states. In this seminar, we will demonstrate how MERA can serve as a novel mathematical and algorithmic language, opening new horizons in quantum cryptography. Finally, we will discuss the role of trapped-ion systems as one of the leading experimental platforms for implementing such networks.
