• Abstract summary: We present a signal enhancement technique that utilizes a superconducting qubit to prepare a superconducting microwave cavity in a non-classical Fock state. We conduct a dark photon search in a band around $mathrm5.965, GHz, (24.67, mu eV)$, where the kinetic mixing angle $epsilon geq 4.35 times 10-13$ is excluded.

• Abstract: The manipulation of quantum states of light has resulted in significant advancements in both dark matter searches and gravitational wave detectors [1-4]. Current dark matter searches operating in the microwave frequency range use nearly quantum-limited amplifiers [3, 5, 6]. Future high frequency searches will use photon counting techniques [1] to evade the standard quantum limit. We present a signal enhancement technique that utilizes a superconducting qubit to prepare a superconducting microwave cavity in a non-classical Fock state and stimulate the emission of a photon from a dark matter wave. By initializing the cavity in an $|n=4\rangle$ Fock state, we demonstrate a quantum enhancement technique that increases the signal photon rate and hence also the dark matter scan rate each by a factor of 2.78. Using this technique, we conduct a dark photon search in a band around $\mathrm{5.965\, GHz \, (24.67\, \mu eV)}$, where the kinetic mixing angle $\epsilon \geq 4.35 \times 10^{-13}$ is excluded at the $90\%$ confidence level.

  Single photon detectors (SPDs) were demonstrated from $gamma$-rays to infrared wavelengths. The energy of $10,mathrmGHz$ microwave photon, about $40,mathrmmu eV$ or $7, mathrmyJ,$ is enough to force a superconducting Josephson junction into its resistive state. The device shows an efficiency up to 40% and a dark count rate of $0.1,mathrmHz$ in a bandwidth of several gigahertz.

• Search for dark photons with synchronized quantum sensor network [18.00599935008738]
  Current constraints on the existence of dark photons with masses below MHz are predominantly set by cosmological or astrophysical limits. Here, we demonstrate a network of 15 atomic magnetometers, which are synchronized with the Global Positioning System (GPS) and are situated on the edges of two meter-scale shielded rooms. Using this network, we constrain the kinetic mixing coefficient of dark photon dark matter over the mass range 1-500 Hz, which gives the strongest constraint of a terrestrial experiment within this mass window.

• An experimental setup to generate narrowband bi-photons via four-wave mixing in cold atoms [0.0]
  We create near-infrared and narrow-band correlated photon pairs by inducing four-wave mixing in a cold gas of $87$Rb atoms confined in a magneto-optical trap. The non-classical nature of the photons pairs is confirmed by observing a violation of Cauchy-Schwarz inequality by a factor of 5.6 $times 105$ in a Hanbury Brown - Twiss interferometer. The combination of high brightness and narrow-band spectrum makes this photon-pair source a viable tool in fundamental studies of quantum states and opens the door to use them in quantum technologies
