Description
Superconducting qubits are sensitive to noise - from electromagnetic disturbances, impurities in the material, and even cosmic rays can easily perturb their quantum states and induce errors. From the quantum computer point of view, none of these are desirable. On the other hand, this very sensitivity implies that qubits can be used as highly sensitive sensors for weak fields—such as dark matter. DarQ experiment (Dark matter search using Qubits) is a research effort to search for wave-like dark matter using superconducting qubits.
In this talk, the concept, status, and prospects of the experiment are discussed, as well as the possibility of using quantum computers themselves as dark matter detectors.
