Quantum And An Error-Corrected Logical Qubit
As we look further into the future, there are types of problems that classical computing will not be able to solve in a reasonable time. Quantum computing represents a fundamental shift, because it harnesses the properties of quantum mechanics and gives us the best chance of understanding the natural world.
Achieving our quantum milestone was a tremendous accomplishment, but we are still at the very beginning of a multi-year journey. One problem we face today is that our physical qubits are very fragile. Even cosmic rays from outer space can destroy quantum information.
To solve more complex problems, our next milestone is to create an error-corrected logical qubit. It’s simply a collection of physical qubits stable enough to hold quantum information for a long period of time. We start by reducing the error rate of our physical qubits, then combining 1,000 physical qubits to create a single logical qubit, and then scaling that up to 1000 logical qubits, at which point, we will have created an error-corrected quantum computer.
Today, we are focused on enabling scientists and developers to access beyond-classical computational resources. But we hope to one day create an error-corrected quantum computer, and success could mean everything from increasing battery efficiency, to creating more sustainable energy, to improved drug discovery and so much more. The roadmap begins in our new data center, which we are calling the Quantum AI campus (in Santa Barbara, Calif.).
We recognize that building an error-corrected quantum computer will be incredibly challenging. But solving hard problems and advancing the state of the art is how we build the most helpful products.
