Quantum Computing, Communication, and Sensing

TL;DR;
- The potentials and commercial applications in the NISQ era for Quantum computing, Quantum communication, and Quantum sensing.
- Quantum computing applications for optimization, machine learning, and chemistry. Quantum communication applications with classical (e.g., PQC) or Quantum approach (e.g., QKD). Quantum sensing applications for medical devices, aerospace, and defense industries.
