Quantum Realm

Although the path ahead for quantum computing is anything but certain, our analysis suggests companies will have the resources needed to make continued progress.

Accelerating technological breakthroughs, increasing investment flows, start-up proliferation, and promises of capable quantum systems by 2030 signal it’s time for business leaders to begin planning their quantum-computing strategies.

Our latest Quantum Technology Monitor shows industry interest remains strong, China is upping its game, and talent shortages require attention.

Causal influences are at the core of any empirical science, the reason why its quantification is of paramount relevance for the mathematical theory of causality and applications. Quantum correlations, however, challenge our notion of cause and effect, implying that tools and concepts developed over the years having in mind a classical world have to be reevaluated in the presence of quantum effects. Here, we propose the quantum version of the most common causality quantifier, the average causal effect, measuring how much a target quantum system is changed by interventions on its presumed cause. Not only does it offer an innate manner to quantify causation in two-qubit gates but also in alternative quantum computation models such as the measurement-based version, suggesting that causality can be used as a proxy for optimizing quantum algorithms. Considering quantum teleportation, we show that any pure entangled state offers an advantage in terms of causal effects as compared to separable states. This broadness of different uses showcases that, just as in the classical case, the quantification of causal influence has foundational and applied consequences and can lead to a yet totally unexplored tool for quantum information science.
