Continuous-variable quantum repeaters based on bosonic error-correction and teleportation: architecture and applications

Bo-Han Wu et al.

Summary: This paper introduces a CV quantum-repeater architecture based on CV quantum teleportation, which is assisted by the Gottesman-Kitaev-Preskill code to suppress physical noise. The designed CV quantum-repeater architecture significantly improves the performance of entanglement-assisted communication, target detection based on quantum illumination, and CV quantum key distribution.

Axion haloscope array with PT symmetry

Yifan Chen et al.

Summary: We generalize the PT-symmetric axion haloscope to a larger array with more PT-symmetric structures, significantly enhancing the optimized scan rate and signal power without increasing readout noise. The robustness of the detector towards variations in array coupling is maximized when a binary tree structure with enhanced PT symmetry is introduced. The scan rate can be further increased through the correlation of signals from multiple probing sensors. This type of array greatly boosts the search for axions, especially in detection using a superconducting radio-frequency cavity with an ac magnetic field.

Search for Invisible Axion Dark Matter in the 3.3-4.2 μeV Mass Range

C. Bartram et al.

Summary: Our experiment reported results from a haloscope search for axion dark matter, excluding the axion-photon coupling predicted by a benchmark model. The sensitivity was achieved through the use of a large-volume cavity, a superconducting magnet, an ultra low noise Josephson parametric amplifier, and subKelvin temperatures. The validity of the detection procedure was ensured by injecting and detecting blind synthetic axion signals.

Searching for Dark Matter with a Superconducting Qubit

Akash Dixit et al.

Summary: A novel microwave photon counting technique has been developed and a new exclusion limit on hidden photon dark matter has been proposed. By repeatedly making quantum nondemolition measurements of cavity photons with a superconducting qubit and applying hidden Markov model analysis, noise has been reduced to 15.7 dB below the quantum limit, enhancing sensitivity to the dark matter signal.

Ohjoon Kwon et al.

Summary: The Center for Axion and Precision Physics Research at the Institute for Basic Science in South Korea is conducting a search for axion dark matter using ultralow temperature microwave resonators. They have reported the exclusion of specific axion mass ranges and larger coupling sensitivity in other ranges for the first time. This study is the first to achieve results with a resonator physical temperature below 40 mK.

Searching for Dark Particles with Quantum Optics

J. Estrada et al.

Summary: Researchers propose a method to search for physics beyond the standard model using optical tools from quantum imaging and communication, focusing on dark-SPDC events where a new dark-sector particle replaces the idler. By the presence of an optical medium, the phase space of the down-conversion process is opened, which would be forbidden in a vacuum. They suggest search schemes that use optical imaging and/or spectroscopy of the signal photons, and analyze the characteristics of optical media required to enhance dSPDC and estimate the rate.

Error-Detected State Transfer and Entanglement in a Superconducting Quantum Network

Luke D. Burkhart et al.

Summary: Microwave photons are used to wire up modular quantum processors, with a low-loss bus resonator coupling bosonic qubits across a superconducting network to mitigate loss effects. A multiphoton qubit transfer and entanglement protocol using Hong-Ou-Mandel interference and error detection demonstrated improved fidelity and success probability, presenting new opportunities for resource-efficient direct gates between modules.

Dark matter interferometry

Joshua W. Foster et al.

Summary: The next generation of ultralight dark matter direct detection experiments will utilize multiple detectors operating at different terrestrial locations to confirm sub-eV bosons as the dominant source of DM. By combining data from multiple detectors, directional information about the DM phase space distribution can be constrained. Additionally, it is shown that the signal in multiple detectors exhibits a daily modulation effect unique to wavelike DM.
