• Title: Conceptual study of a two-layer silicon pixel detector to tag the passage of muons from cosmic sources through quantum processors
• Authors: Ulascan Sarica
• Abstract summary: In quantum computing, the contribution of muons from cosmic sources can constitute a significant fraction of these interactions. A conceptual study of a two-layer silicon pixel detector to tag their hits on a solid-state quantum processor is presented. We propose a novel research program that could allow the development of silicon pixel detectors that are fast enough to provide input to quantum error correction algorithms.

• Abstract: Recent studies in quantum computing have shown that quantum error correction with large numbers of physical qubits are limited by ionizing radiation from high-energy particles. Depending on the physical setup of the quantum processor, the contribution of muons from cosmic sources can constitute a significant fraction of these interactions. As most of these muons are difficult to stop, we perform a conceptual study of a two-layer silicon pixel detector to tag their hits on a solid-state quantum processor instead. With a typical dilution refrigerator geometry model, we find that efficiencies greater than 50% are most likely to be achieved if at least one of the layers is operated at the deep-cryogenic (<1 K) flanges of the refrigerator. Following this finding, we further propose a novel research program that could allow the development of silicon pixel detectors that are fast enough to provide input to quantum error correction algorithms, can operate at deep-cryogenic temperatures, and have very low power consumption.

  We propose a novel method to significantly enhance the signal rate in qubit-based dark matter detection experiments. We show that the signal rate scales proportionally to $n_rm q2$, with $n_rm q$ being the number of sensor qubits. In the dark matter detection with a substantial number of sensor qubits, a significant increase in the signal rate can be expected.
