We are progressing through the Quantum Decade, the decade when enterprises begin to see business value from quantum computingonce viewed as a futuristic technology that would change everything, if it ever moved from the fantastical to the practical.

What can and should farsighted leaders and organizations do to position themselves effectively in this brave new era? Our key learnings, explained in detail in the latest edition of The Quantum Decade, revolve around phases of organizational evolutionfrom Quantum Awareness to Quantum Advantage.

Whats new in the third edition of The Quantum Decade:

Quantum Advantage: A process, not a destination

When quantum demonstrates its superiority over traditional computing for a specific problem, thats Quantum Advantage. Its gradual, coming in waves that both progress and pause, but ultimately move the technology forward.

CEOs of Fortune 500 companies have a once-in-a lifetime opportunity. They cannot afford to play catchup.

Industry use case

By combining hybrid classical and quantum resources, IBM and Boeing are advancing quantum chemistry research on the mechanism for corrosion.

Designing corrosion-resistant materials is a critical task that could make airplanes easier to maintain, but performing experiments on these new materials is often very expensive or otherwise impractical. Numerical simulations present a much more practical alternative for researchers who wish to model and study the molecular systems that make up experimental materials. However, classical computers are only able to create approximate simulations of molecular systems, and those approximations become even less accurate when dealing with molecular systems that are large in size.

Quantum computers, by contrast, have the potential to compute precise simulations of even incredibly complex molecular systems. However, these systems may be too large for our current generation of quantum hardware to simulate them all at once. Thats why researchers use a class of techniques called circuit knitting to break up those larger molecular systems into smaller simulation problems.

A circuit knitting technique like quantum embedding, for example, makes it possible to focus the quantum computers efforts on a tractable partition of the full simulation problem. When researchers combine circuit knitting with classical pre- and post- processing techniques like active space selectionwhich serves to identify the portion of the chemical system that is active during chemical reactionsthey can extrapolate their solutions to understand properties of the entire system.

Researchers from IBM and Boeing collaborated to develop automated methods of active space selection suited to studying not only corrosion but all manner of chemical reactions that take place on surfaces. By leveraging local embedding methods with the designated active spaces, the researchers were able to use variational quantum algorithms to study the splitting of a water molecule on a magnesium surface. At the time of completion, this study represented one of the first ever instances of quantum algorithms being used to investigate surface reactions.
