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.

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 initial speed of our modular quantum computer will be limited by the connection rate between modules, but for small problems, the computation speed won't be a major concern.

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.

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.
