A theoretical ceiling of 127 fully entangled logical qubits would limit quantum state space to 2^127, potentially capping computational power.
This constraint could hinder solving classically intractable problems requiring larger qubit counts, like advanced cryptography or material simulations.
However, 127 qubits may still suffice for near-term quantum advantage in optimization, chemistry, and machine learning applications.
The industry's long-term ambitions, such as fault-tolerant quantum computing, might require surpassing this limit to unlock full potential.
If physically unavoidable, research would shift focus to maximizing efficiency within this bound rather than scaling qubit numbers.

Summarize this article with:
Would it be a problem for Quantum Computing if there is a strict ceiling to fully big the state space can get say 2^127 , ie. if it turns out to be physically impossible to have more than 127 fully entangled (logical) qubits? Is it good enough for the industry's ambitions? submitted by /u/Background-Eye9365 [link] [comments]
