When we joined Y Combinator in summer 2014, we had not built a single qubit, the fundamental building block of a quantum computer.

In the last three years, there's been a surge of interest from companies wanting to collaborate with academics on quantum computing research, marking a significant shift from previous years when companies were hesitant to invest.

The quantum computing field is diversifying, and there are now opportunities for software engineers and systems engineers to contribute without needing deep quantum physics knowledge.

To be genuinely useful, a quantum computer needs to exceed 50 qubits, as tasks requiring fewer qubits can still be efficiently simulated by classical computers, making them less impactful.

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.

Quantum startups are increasingly concentrated in the Bay Area due to the presence of the tech industry and investors interested in financing innovative technical ventures. This trend may continue as the field develops.

A single quantum chip with 60 or 70 qubits could outperform a traditional supercomputer that occupies half a football field.

Quantum computing has gained significant attention recently because it's starting to work in labs, reaching a point where it can perform tasks that classical computers cannot.

When forming a team for a quantum computing startup, it's crucial to have individuals with diverse expertise. Effective communication across different areas of knowledge, such as software and control engineering, is vital for success in this complex field.
