Quantum Computing and Secure Communication Advances

Quantum Computing Evolution: • Satellite-Based Quantum Communication: Develop intermediate-scale quantum computers

with 20-50 physical qubits (3 years), 50-100 physical qubits (5 years), and 50-1000

physical qubits (8 years) across platforms like superconducting and photonic technologies to

advance computational capabilities.Establish satellite-enabled quantumsecured communication between two ground

stations over 2000 km within India and extend this technology for long-distance secure quantum communication

with other countries.• Inter-City Quantum Key Distribution (QKD): Implement quantum-secured

communication spanning 2000 km using trusted nodes and wavelength division multiplexing (WDM)

on existing optical fiber infrastructure, enhancing secure data transmission.• Multi-Node Quantum
