Impact of potential changes to quantum mechanics on quantum computing

Investigate how hypothetical modifications to the foundational theory of quantum mechanics would affect the theory and practice of quantum computing and quantum information, including implications for models, algorithms, and capabilities.

Background

While quantum mechanics is currently regarded as the most accurate physical theory at microscopic scales, the authors note it might require future modifications. The consequences of such changes for quantum computation and information are uncertain.

They emphasize that any new physical theory could potentially yield a new computational paradigm, possibly more powerful than current quantum computing.

References

If and when such a scenario becomes a reality, it is unclear how will that change in the theory of quantum mechanics reflect on quantum computing and quantum information; however, "the novel physical theory that will emerge may give rise to a new computational paradigm, maybe even more powerful than quantum computing."
