Hybrid quantum computer observes foundational quantum effect in a new setting
Physicists in the Department of Physics at the University of Oxford have used a hybrid quantum computer, made up of qubits and quantum oscillators, to observe the Aharonov–Bohm effect in a quantum simulation.
Physicists in the Department of Physics at the University of Oxford have used a hybrid quantum computer, made up of qubits and quantum oscillators, to observe the Aharonov–Bohm effect in a quantum simulation.
The short version
- The effect is a quantum phenomenon in which a particle can acquire a measurable phase by traveling around a magnetic flux, even though it never passes through a region where a magnetic field is present.
- This article has been reviewed according to Science X's editorial process and policies .
- The result demonstrates how hybrid quantum systems can be used to simulate interactions between matter and gauge fields that become increasingly difficult to model on classical computers.
What happened
The paper has been published in Nature Physics . Physicists are now interested in seeing the effect emerge in a different setting: lattice gauge theories.
Why it matters
These are mathematical frameworks used to describe interactions between matter and gauge fields, including important models in particle and high-energy physics.
