• Title: Quantum rotation sensor with real-time readout based on an atom-cavity system
• Authors: Jim Skulte, Jayson G. Cosme, Ludwig Mathey
• Abstract summary: We propose to combine the effective gauge phase of rotated neutral atoms and the superradiant phase transition to build a highly sensitive and fast quantum rotation sensor. The atoms in a well-controlled array of Bose-Einstein condensates are coupled to a single light mode of an optical cavity. The photon emission from the cavity indicates changes in the rotation frequency in real time, which is crucial for inertial navigation.

• Abstract: Using an atom-cavity platform, we propose to combine the effective gauge phase of rotated neutral atoms and the superradiant phase transition to build a highly sensitive and fast quantum rotation sensor. The atoms in a well-controlled array of Bose-Einstein condensates are coupled to a single light mode of an optical cavity. The photon emission from the cavity indicates changes in the rotation frequency in real time, which is crucial for inertial navigation. We derive an analytical expression for the phase boundaries and use a semi-classical method to map out the phase diagram numerically, which provides the dependence of the photon emission on the rotation. We further suggest to operate the sensor with a bias rotation, and to enlarge the enclosed area, to enhance the sensitivity of the sensor.

  Microwave or radio-frequency driving poses a significant limitation for miniaturization, energy-efficiency and non-invasiveness of quantum sensors. We overcome this limitation by demonstrating a purely optical approach to coherent quantum sensing. Our results pave the way for highly compact quantum sensors to be employed for magnetometry or gyroscopy applications.

  We demonstrate the control of giant polarisation rotations induced by a single electron spin. We find that the polarisation state of the reflected photons can be manipulated in most of the Poincar'e sphere, through controlled spin-induced rotations. This control allows the operation of spin-photon interfaces in various configurations, including at zero or low magnetic fields.

• Bosonic pair production and squeezing for optical phase measurements in long-lived dipoles coupled to a cavity [0.0]
  Entanglement between atoms, generated by the exchange of virtual photons through a common cavity mode, grows exponentially fast. We propose to exploit this for quantum-enhanced sensing of an optical phase (common and differential between two ensembles) Our proposal can open unique opportunities for the observation of continuous variable entanglement in atomic systems and associated applications in next-generation optical atomic clocks.

• Optical Entanglement of Distinguishable Quantum Emitters [0.0]
  We propose and demonstrate an efficient method for entangling emitters with optical transitions separated by many linewidths. In our approach, electro-optic modulators enable a single photon to herald a parity measurement on a pair of spin qubits. Working with distinguishable emitters allows for individual qubit addressing and readout, enabling parallel control and entanglement of both co-located and spatially separated emitters.

We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.
