Can I get a sense of the complexity achievable with quantum computing with, say, 20 atoms?

With 20 atoms acting as qubits in a quantum computer, you can achieve a moderate level of complexity. Here’s what you should know:

• Computational Power: 20 qubits allow for calculations within a state space of 2²⁰ (over a million) possible combinations. This surpasses the capabilities of classical computers for certain types of problems.
• Potential Applications:
• Quantum simulations: Simulate small molecules or simple materials with higher accuracy than classical methods.
• Optimization problems: Potentially find better solutions to optimization problems with a limited number of variables.
• Machine learning: Explore quantum machine learning algorithms for specific tasks.
• Limitations:
• Error correction: Quantum computers are susceptible to errors. With current technology, 20 qubits might not be enough for robust error correction, limiting the complexity of problems they can solve reliably.
• Noise: Environmental noise can disrupt quantum computations. Isolating and controlling 20 qubits…
