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…
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…
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…
