As long as the quantum modules have good memory and quality internal operations, we can take a poor quality link and enhance it to function as a high-quality link.

Using multiple links in quantum communication can improve the quality of information transfer, similar to how conventional technology compensates for weak signals by requesting data multiple times to ensure accuracy.

We can create qubits that are entangled at 90% quality, but we can store them practically forever, allowing us to enhance their quality through a process similar to improving a staticky communication channel.

Network approaches to quantum computing enable any qubit to link with any other qubit, enhancing connectivity and power, despite the increased risk of errors if not managed correctly.

To determine if a quantum computer can be modular, we need to assess whether we can achieve good quality entanglements between two modules, which would prove they are part of the same quantum state.

Improving the reliability of quantum gates and reducing error rates will be crucial for scaling quantum computers and enabling them to solve more complex problems.

If you can't achieve entanglement between the Alice module and the Bob module, your quantum machine will essentially remain a collection of separate units, unable to perform a unified quantum calculation.

The key to effective quantum computing is ensuring qubits interact as desired, rather than just focusing on increasing coherence times.

The approach to scalability in quantum computing involves creating small, efficient quantum modules that can be linked together, rather than trying to scale up a single large quantum computer, which presents numerous challenges.
