To continue this progress in quantum computing, we need better materials, fabrication, and control methods, particularly using microwave circuitry.

At Rigetti Computing, we're driving the transition from microchips to systems based on individual atoms or artificial atoms that we build in the lab.

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.

Integration within a hard tech organization allows for the creation of defensibility, enabling the development of a comprehensive business model in quantum computing.

The potential for quantum computers to simulate chemistry and material systems could lead to breakthroughs in various scientific fields, although the exact number of qubits required for these tasks remains uncertain.

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

In less than two years, we've built a five-qubit quantum computer and grown to about 35 people in a warehouse in Berkeley, including around 20 PhDs.

Feynman proposed the concept of a universal quantum simulator, which we now refer to as a quantum computer, to simulate quantum systems more effectively than classical computers.

The idea that a quantum computer would be powerful was emphasized over 30 years ago by Richard Feynman, who believed that nature is quantum mechanical and that simulating nature should also be quantum mechanical.
