Classical Analog: Microprocessors
• Integrated Circuits Technology (Kilby & Noyce, 1958)
- Scalable technology platform for creating functional circuits
- Reduced the cost and increased the functionality of
electronic functions by a factor of a million in last 30 years

Quantum Version of “IC” Technology
• Physical system dependent
• Capability to integrate ALL ELEMENTS required
• Quantum-classical boundary between the qubits and controller
Matching the temperature, size, speed, etc. is critical!!!
