Quantum Error Correction-like Noise Mitigation for Wave-like Dark Matter Searches with Quantum Sensors
Hajime Fukuda, Takeo Moroi, Thanaporn Sichanugrist
We propose a quantum error correction-like noise mitigation protocol for enhancing the sensitivity of wave-like dark matter searches with quantum sensors. Our protocol uses multipl…
Magnetic Helicity, Magnetic Monopoles, and Higgs Winding
Hajime Fukuda, Yuta Hamada, Kohei Kamada +2
Changes in magnetic helicity are often discussed across a variety of fields, from condensed matter physics to early universe cosmology. It is frequently stated that the helicity ch…
Background Suppression in Quantum Sensing of Dark Matter via Collective Entangled-State Projection
Shion Chen, Hajime Fukuda, Yutaro Iiyama +5
We show that measuring dark matter signal by projecting quantum sensors in the collective excited state can highly suppress the non-collective noise background, hence improving the…
Directional search for light dark matter with quantum sensors
Hajime Fukuda, Yuichiro Matsuzaki, Thanaporn Sichanugrist
The presence of dark matter (DM) stands as one of the most compelling indications of new physics in particle physics. Typically, the detection of wave-like DM involves quantum sens…
Search for Dark Photon Dark Matter with a Mass around 36.1 μeV Using a Frequency-tunable Cavity Controlled through a Coupled Superconducting Qubit
Kan Nakazono, Shion Chen, Hajime Fukuda +10
We report the results of a search for dark photon dark matter using a cavity that employs a transmon qubit as a frequency tuner. The tuning mechanism utilizes the energy level shif…
Entanglement-enhanced AC magnetometry in the presence of Markovian noises
Thanaporn Sichanugrist, Hajime Fukuda, Takeo Moroi +5
Entanglement is a resource to improve the sensitivity of quantum sensors. In an ideal case, using an entangled state as a probe to detect target fields, we can beat the standard qu…
Non-thermal production of Higgsino dark matter by late-decaying scalar fields
Hajime Fukuda, Qiang Li, Takeo Moroi +1
We study the non-thermal production of the Higgsino dark matter (DM). Assuming that the lightest neutral Higgsino is the lightest supersymmetric particle (LSP) in minimal supersymm…
Leptogenesis from magnetic helicity of gauged
Hajime Fukuda, Kohei Kamada, Thanaporn Sichanugrist
If the symmetry is gauged with the addition of right-handed neutrinos, the standard model current is anomalous with respect to the gauge field itself. Then, the a…
Search for QCD axion dark matter with transmon qubits and quantum circuit
Shion Chen, Hajime Fukuda, Toshiaki Inada +3
We propose a direct axion dark matter (DM) search using superconducting transmon qubits as quantum sensors. With an external magnetic field applied, axion DM generates an oscillati…
Quantum Enhancement in Dark Matter Detection with Quantum Computation
Shion Chen, Hajime Fukuda, Toshiaki Inada +3
We propose a novel method to significantly enhance the signal rate in qubit-based dark matter detection experiments with the help of quantum interference. Various quantum sensors p…
Search for WIMPs at future colliders
Hajime Fukuda, Takeo Moroi, Atsuya Niki +1
Weakly interacting massive particles (WIMPs) with electroweak charges, such as the wino and the Higgsino, stand out as natural candidates for dark matter in the universe. In this p…
