An Upper Bound on Effective Quantum Computation?

A recent paper suggests a theoretical upper bound on the number of qubits that can be effectively superposed and entangled in quantum computing, potentially impacting industrial cryptography. The proposed limit is on the interdependence of qubits in a quantum algorithm, not the total number of qubits in a quantum computer. The paper explores the concept of discretized space and its implications for quantum computing, proposing a limit of 1000 qubits for effectively addressing legal states. Practical tests for this limit could be conducted within the next 5-10 years, with potential implications for the future of quantum computing if the theory holds true.
