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 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…
