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.

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.

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 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.

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.

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.

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

Quantum computing is fundamentally different from classical computing, and if you can determine which computational path was taken, you lose the speed advantage that quantum computing offers. It's essential to sum all possible computations without knowing which path was followed to leverage quantum mechanics effectively.

Quantum entanglement is a key property that allows information to be stored in the correlations between parts of a quantum system, making it difficult to access that information by examining individual parts.
