Multiple Technical Approaches Being Developed

1. Superconductors

2. Photons

3. Trapped Ions

4. Quantum Dot

5. Nitrogen Vacancy Centers in Diamond For architectural major architectural approaches include:

6. Quantum Annealing

7. Analog Quantum

8. Gate Level Quantum Computers

9. Topological Quantum Computing In addition, implementations can differ on whether they require error correction or can achieve satisfactory results without using error correction.
