QCodes: Quantum Information and Error-Correction

Quantum information represents an entirely new way of representing, communicating, and computing with information. A complete theory of quantum information continues to this day, combining concepts from physics, mathematics, and computer science.

Quantum processing is particularly susceptible to errors, as good qubits and quantum gates must exist in near-perfect isolation. Researchers in the DQC have pioneered the concept of quantum error correction, refined codes especially suited for our atomic qubits, and have implemented aspects of quantum error correction in real systems.

As we grow and scale our systems to larger numbers of qubits and circuit depths, quantum error correction will become very important to reliably execute quantum applications on our machines. This area of research spans pure mathematics and information/coding theory, and also overlaps strongly with many areas of theoretical physics. Indeed, there may be exotic materials that naturally “error correct,” such as topological materials, that can be simulated on our machines.
