Towards large-scale entanglement-enhanced interferometry

Abstract

We report progress measuring Earth’s rotation with entangled photons. In our 2 km fiber Sagnac interferometer, we achieve milliradian sensitivity with cw light, find a preliminary signal, and work towards injecting 2-photon NOON states.

Experimental observation of Earth’s rotation with quantum entanglement

Raffaele Silvestri, Haocun Yu, Teodor Strömberg +3 more

Precision interferometry with quantum states has emerged as an essential tool for experimentally answering fundamental questions in physics. Optical quantum interferometers are of particular interest because of mature methods for generating and manipulating quantum states of light. Their increased sensitivity promises to enable tests of quantum phenomena, such as entanglement, in regimes where tiny gravitational effects come into play. However, this requires long and decoherence-free processing of quantum entanglement, which, for large interferometric areas, remains unexplored territory. Here, we present a table-top experiment using maximally path-entangled quantum states of light in a large-scale interferometer sensitive enough to measure the rotation rate of Earth. The achieved sensitivity of 5 μrad s −1 constitutes the highest rotation resolution ever reached with optical quantum interferometers. Further improvements to our methodology will enable measurements of general-relativistic effects on entangled photons, allowing the exploration of the interplay between quantum mechanics and general relativity, along with tests for fundamental physics.

By inserting quantum entangled SU(1,1) interferometers into a Sagnac interferometers, we form a Sagnac-SU(1,1) interferometer for rotational sensing. We find the rotational signal comes from ``classical" and ``quantum" parts with the latter enhanced by quantum entanglement.

Entanglement-enhanced optical gyroscope

Matthias Fink, Fabian Steinlechner, Johannes Handsteiner +3 more

Abstract Fiber optic gyroscopes (FOG) based on the Sagnac effect are a valuable tool in sensing and navigation and enable accurate measurements in applications ranging from spacecraft and aircraft to self-driving vehicles such as autonomous cars. As with any classical optical sensors, the ultimate performance of these devices is bounded by the shot-noise limit (SNL). Quantum-enhanced interferometry allows us to overcome this limit using non-classical states of light. Here, we report on an entangled-photon gyroscope that uses path-entangled NOON-states (N = 2) to provide super-resolution and phase sensitivity beyond the shot-noise limit.
