Abstract

We demonstrate the detection of a linear superposition of two distributed phases with a 1.7 dB quantum noise reduction using a tSU(1,1) interferometer. We extend the system theoretically to a multi-phase distributed sensing scheme.

Quantum-enhanced distributed phase sensing with a truncated SU(1,1) interferometer

Seongjin Hong, Matthew A. Feldman, Claire E. Marvinney +5 more

In recent years, distributed quantum sensing has gained interest for a range of applications requiring networks of sensors, from global-scale clock synchronization to high energy physics. In particular, a network of entangled sensors can improve not only the sensitivity beyond the shot noise limit, but also enable a Heisenberg scaling with the number of sensors. Here, using bright entangled twin beams, we theoretically and experimentally demonstrate the detection of a linear combination of two distributed phases beyond the shot noise limit with a truncated SU(1,1) interferometer. Specifically, we show a quantum noise reduction of 1.7 ± 0.3 dB below what is possible with the corresponding classical configuration. Additionally, we theoretically extend the use of a truncated SU(1,1) interferometer to a multi-phase-distributed sensing scheme that leverages entanglement as a resource to achieve a quantum improvement in the scaling with the number of sensors in the network. Our results pave the way for developing quantum-enhanced sensor networks that can achieve an entanglement-enhanced sensitivity.

Distributed phase sensing using two-mode squeezed states in a truncated SU(1,1) interferometer

Seongjin Hong, Matthew A. Feldman, Claire E. Marvinney +3 more

We demonstrate distributed phase sensing with a truncated SU(1,1) interferometer through the measurement of a linear combination of two phases distributed between the two beams of a two-mode squeezed state. We theoretically analyze the sensitivity enhancement with respect to the corresponding classical strategy and experimentally demonstrate a 2 dB quantum noise reduction in the measurement of a linear combination of two phases.

Quantum twin interferometers

Quantum-correlated interferometer is an emerging tool in quantum technology that offers classical-limit-breaking phase sensitivity. However, to date, there exists a configurational bottleneck for its practicability due to the low phase-sensing power limited by the current detection strategies. Here, we establish an innovative development termed as "quantum twin interferometer" with dual pairs of entangled twin beams arranged in the parallel configuration, allowing full exploitation of the quantum resource through the configuration of entangled detection. We observe the distributed phase sensing with 3-decibel quantum noise reduction in phase-sensing power at the level of milliwatts, which advances the record of signal-to-noise ratio so far achieved in photon-correlated interferometers by three orders of magnitude. The developed techniques in this work can be used to revolutionize a diversity of quantum devices requiring phase measurement.

Quantum-Enhanced Interferometer for Multiphase Sensing

Yanni Feng, Zhaoqing Zeng, Jialin Cheng +6 more

Quantum-enhanced interferometers have been widely used in single-parameter precision measurement, and multiparameter precision measurement is the building block of numerous sensing and imaging applications. However, it remains challenging to realize high-sensitivity multiparameter sensing without increasing power, which is crucial for biological science. Here, we propose and demonstrate a deterministic quantum-enhanced interferometer, where high-sensitivity multiparameter sensing is realized by effectively squeezing noises and amplifying signals. Key technologies are essential to the results, including the parallel and sequential use of squeezed states inside the interferometer. Notably, in the quantum-enhanced three-arm interferometer, not only joint but also individual values of three signals are simultaneously measured with a signal-to-noise ratio of more than 10.37±0.13 dB compared with that of the conventional interferometer under the same phase-sensing power. These advances constitute a critical step toward observing multiple elusive signals and give rise to a wide range of sensing and imaging applications.
