Abstract

Detection based on quantum principles such as entanglement has the capacity to achieve finessed levels of sensitivity, bringing transformative impacts to applications. In this study, we propose a rotation sensor using ultra-cold dipolar atoms trapped in a four-well configuration. The design, based on a simple population imbalance measurement to quantify rotation, profits from the property of superintegrability. The implementation of the measurement protocol achieves rotation-detection sensitivity beyond the Heisenberg limit. Our results spotlight superintegrability opportunities for advancing the field of quantum sensing.

High-fidelity transfer of entangled states on a quantum turntable

Leandro Hayato Ymai, Karin Wittmann Wilsmann, Arlei Prestes Tonel +2 more

The reliable transfer of quantum states lies at the heart of developing quantum technologies. Several platforms have been proposed to achieve this, leveraging the properties offered by cold atom systems. In this direction, we design a quantum turntable to spatially transfer entangled bosonic states. It is implemented via a rotating, tetrahedral circuit. The proposal is guided by the property of superintegrability, offering a rich theoretical framework to build upon. To illustrate the process, NOON states and generalizations are employed. The performance is quantified through fidelity analyses. We identify the occurrence of a phase shift during the operation, with potential applications for quantum sensing. We also discuss the feasibility of engineering the system through ultracold dipolar atoms. Our results showcase the benefits of superintegrability in the design of supersensitive quantum architectures.

Tunneling control of dipolar boson in triple well circuit via dipole polarization orientation and quantum sensing application

Leandro Hayato Ymai, Arlei Prestes Tonel

Precise control of the transport of ultra-cold atoms in optical lattices is essential for the exploration of quantum phenomena and the development of advanced quantum technologies. Harnessing the distinctive characteristics of the system near integrability, we investigate the tunneling control of dipolar bosons confined within a triple-well circuit via dipole polarization orientation. Based on this control mechanism, we propose a quantum magnetic compass that shows sensitivity beyond the Heisenberg limit to small variations in the orientation of magnetic fields, making it a promising candidate for sensing applications.

Quantum Sensors Based on Quantum Isotopes

Jincheng Zhang

This paper explores the potential of quantum isotopes as the foundation for developing high-precision and high-sensitivity quantum sensors. Traditional sensors are often limited by inherent noise and fundamental physical constraints, hindering their ability to measure extremely small physical quantities with high accuracy. Quantum isotopes, possessing unique properties derived from their nuclear structure – specifically, their quantized spin or nuclear energy levels – offer a pathway to overcome these limitations. This work details the theoretical framework for leveraging these isotopes in sensor design, focusing on utilizing their inherent sensitivity to external forces and fields. The proposed approach relies on the precise measurement of shifts in these energy levels, providing a mechanism for detecting and quantifying weak interactions. The core claim of this research is the ability to construct highly accurate and sensitive quantum sensors through the exploitation of quantum isotopic characteristics. This paper outlines the key principles, potential applications, and the anticipated advancements enabled by this technology. ---

Vectorial quantum sensors

Philippe Bouyer

Inertial sensors based on cold atoms and light-pulse interferometry exhibit state-of-the-art sensitivity and ultra-low measurement bias that could revolutionize a variety of fields including geophysics and seismology, gravitational wave detection and fundamental tests of gravity, and inertial navigation. In the latter case, cold-atom interferometers are widely considered as breakthrough technology for future autonomous INSs. Nowadays, absolute quantum inertial sensors are available as commercial and field-deployable devices. Yet, their current size and complexity has not yet reached a technology readiness level compatible with mobile applications or plug-and-play operation by non-specialists. These systems are in desperate need of further development and miniaturization. We will present progress beyond these first experiments while exploring new methods relying on 3D matter-wave manipulation that can lead to interferometer geometries that are simultaneously sensitive to accelerations and rotations in 3D and can discern their vector components within a single measurement. These novel innovations produce additional sensitivity to rotations and gravity gradients which has not yet been exploited experimentally and could be a game changing innovation for future atomic sensors. The ability to measure the full acceleration and rotation vectors with a compact, high-precision, low-bias inertial sensor could strongly impact the fields of inertial navigation, gravity gradiometry, and gyroscopy.

Interacting Atomic Interferometry for Rotation Sensing Approaching the Heisenberg Limit

Stephen Ragole, Jacob M. Taylor

Atom interferometers provide exquisite measurements of the properties of noninertial frames. While atomic interactions are typically detrimental to good sensing, efforts to harness entanglement to improve sensitivity remain tantalizing. Here we explore the role of interactions in an analogy between atomic gyroscopes and SQUIDs, motivated by recent experiments realizing ring-shaped traps for ultracold atoms. We explore the one-dimensional limit of these ring systems with a moving weak barrier, such as that provided by a blue-detuned laser beam. In this limit, we employ Luttinger liquid theory and find an analogy with the superconducting phase-slip qubit, in which the topological charge associated with persistent currents can be put into superposition. In particular, we find that strongly interacting atoms in such a system could be used for precision rotation sensing. We compare the performance of this new sensor to an equivalent noninteracting atom interferometer, and find improvements in sensitivity and bandwidth beyond the atomic shot-noise limit.

Super-sensitive rotation measurement with an orbital angular momentum atom-light hybrid interferometer

Sheng Ming

Lights carrying orbital angular momentum (OAM) have potential applications in precise rotation measurement, especially in remote sensing. Interferometers, especially nonlinear quantum interferometers, have also been proven to greatly improve the measurement accuracy in quantum metrology. By combining these two techniques, we theoretically propose a new atom-light hybrid Sagnac interferometer with OAM lights to advance the precision of the rotation measurement. A rotation sensitivity below standard quantum limit is achieved due to the enhancement of the quantum correlation of the interferometer even with 96% photon losses. This makes our protocol robustness to the photon loss. Furthermore, combining the slow light effect brings us at least four orders of magnitude of sensitivity better than the earth rotation rate. This new type interferometer has potential applications in high precision rotation sensing.
