We plan to build a modular quantum computer made of small quantum modules that, when linked, can work together to form a unified quantum state.

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.

The timeline for building a modular quantum computer depends on interest and investment, but demonstrating two fully linked modules is an immediate goal for the next year.

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.

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.

The ability to perform hundreds of thousands of operations per second in quantum computing means that even a short decoherence time can be sufficient for many calculations.

The challenge in quantum computing lies in scaling; while achieving high fidelity with a small number of qubits is possible, creating a robust system that consistently performs well with a larger number of qubits is a significant engineering problem.

Quantum computing offers a faster and cheaper path to achieving high levels of computing power compared to traditional methods.
