“…In France, significant progress has been made towards the 200 m baseline underground gravitational wave detector prototype MIGA (Matter-wave laser based Interferometer Gravitation Antenna) [20]. A follow-on proposal has called for the construction of ELGAR (European Laboratory for Gravita-tion and Atom-interferometric Research) [21,69], an underground detector with horizontal 32 km arms aiming to detect gravitational waves in the mid-band (infrasound) frequency range. In China, work has started to build ZAIGA (Zhaoshan long-baseline Atom Interferometer Gravitation Antenna) [23], a set of 300 m vertical shafts separated by kilometer-scale laser links that will use atomic clocks and atom interferometry for a wide range of research, including gravitational wave detection and tests of general relativity.…”

A wide range of quantum sensing technologies are rapidly being integrated into the experimental portfolio of the high energy physics community. Here we focus on sensing with atomic interferometers; mechanical devices read out with optical or microwave fields; precision spectroscopic methods with atomic, nuclear, and molecular systems; and trapped atoms and ions. We give a variety of detection targets relevant to particle physics for which these systems are uniquely poised to contribute. This includes experiments at the precision frontier like measurements of the electron dipole moment and electromagnetic fine structure constant and searches for fifth forces and modifications of Newton's law of gravity at micron-to-millimeter scales. It also includes experiments relevant to the cosmic frontier, especially searches for gravitional waves and a wide variety of dark matter candidates spanning heavy, WIMP-scale, light, and ultra-light mass ranges. We emphasize here the need for more developments both in sensor technology and integration into the broader particle physics community.

“…Other projects are in their very preliminary study phase, as is the case of the Italian project MAGIA-Advanced, which is studying the feasibility of a vertical instrument with a baseline of a few 100s meters to be installed in a former mine shaft in Sardinia [33], or are at the stage of study proposals such as the The European Laboratory for Gravitation and Atom-interferometric Research (ELGAR) [33,31] and the Atomic Experiment for Dark Matter and Gravity Exploration in Space (AEDGE) [50].

Quantum sensors exploiting matter waves interferometry promise to realize a new generation of Gravitational Wave detectors. The intrinsic stability of specific atomic energy levels makes atom interferometers and clocks ideal candidates to extend the frequency window for the observation of Gravitational Waves in the mid-frequency band, ranging from 10 mHz to 10 Hz. We present the geometry and functioning of this new class of ground and space detectors and detail their main noise sources. We describe the different projects undertaken worldwide to realize large scale demonstrators and push further the current limitations. We finally give the roadmap for achieving the instrumental sensitivity required to seize the scientific opportunities offered by this new research domain.

“…where to estimate the parameter φ err /k, one can use the Eqs. (2)(3)(4). Despite the fact that at each step the error (6) does not depend on T , the total error ∆X during navigation time t n accumulates after repeated measurement of phases at times multiple to T , .…”

Local positioning system as a classic alternative to atomic navigation

A local positional system (LPS) is proposed, in which particles are launched at given velocities, and a sensor system measures the trajectory of particles in the platform frame. These measurements allow us to restore the position and orientation of the platform in the frame of the rotating Earth, without solving navigation equations. When the platform velocity is known and if the platform orientation stays the same, the LPS-technique allows a navigational accuracy of 100µ per one hour to be achieved. In this case, the LPS technique is insensitive to the type of platform trajectory. If there are also velocimeters installed on the platform, then one can restore the velocity and angular rate of the platform rotation in respect to the Earth. Instead of navigational equations, it is necessary to obtain the classical trajectory of a particle in the field of a rotating gravity source. Taking into account the gravity-gradient, Coriolis, and centrifugal forces, the exact expression for this trajectory is derived, which can be widely used in atomic interferometry. A new iterative method for restoring the orientation of the platform without using gyroscopes is developed. The simulation allowed us to determine the conditions under which the LPS-navigation error per hour is about 10m.
