Abstract

We demonstrate a sub-shot noise quantum optical sensor combining path entan- glement and standard intensity detection. Exploiting our exceptionally high sampling rates (100 kHz), we implement an optical microphone, allowing humans to hear the quantum advantage.

Quantum Optical Microphone in the Audio Band

The ability to perform high-precision optical measurements is paramount in science and engineering.Laser interferometry enables interaction-free sensing with a precision ultimately limited by shot noise.Quantum optical sensors can surpass this limit but single-or multiphoton schemes are challenged by low experimental sampling rates, while squeezed-light approaches require complex optical setups and sophisticated time gating.Here, we introduce a simple method that infers optical phase shifts through standard intensity measurements while still maintaining the quantum advantage in the measurement precision.Capitalizing on the robustness and high sampling rates of our device, we implement a quantum optical microphone in the audio band.Its performance is benchmarked against a classical laser microphone in a standardized medically approved speech-recognition test on 45 subjects.We find that quantum-recorded words improve the speech-recognition threshold by -0.57dB SPL , thus making the quantum advantage audible.Not only do these results open the door toward applications in quantum nonlinear interferometry but they also show that quantum phenomena can be experienced by humans.

Hearing the Quantum Difference

Hearing the Quantum DifferenceAt very low volume, a quantum optical microphone performs better than a classical device, and humans can hear the difference.By Michael Schirber Q uantum devices are often touted as performing better than classical ones, but the impact can seem far from our everyday lives.Researchers have now demonstrated a quantum optical microphone that listeners say produces a clearer sound than a classical counterpart [1].The microphone was tested under specific conditions (low volume and high noise), outside of which the quantum advantage would not be noticeable.Despite this limitation, the new quantum techniques could prove useful elsewhere: they could eventually be used to improve imaging of biological samples.Many high-precision measurements, such as gravitational-wave detection, rely on interferometers that measure interference effects, such as fringes, that arise when photons are sent through two possible paths.Using pairs of

Quantum Sensing with Squeezed Light

Benjamin J. Lawrie, Paul D. Lett, Alberto M. Marino +1 more

The minimum resolvable signal in sensing and metrology platforms that rely on optical readout fields is increasingly constrained by the standard quantum limit, which is determined by the sum of photon shot noise and back-action noise. A combination of back-action and shot noise reduction techniques will be critical to the development of the next generation of sensors for applications ranging from high-energy physics to biochemistry and for novel microscopy platforms capable of resolving material properties that were previously obscured by quantum noise. This Perspective reviews the dramatic advances made in the use of squeezed light for sub-shot-noise quantum sensing in recent years and highlights emerging applications that enable new science based on signals that would otherwise be obscured by noise at the standard quantum limit.

Generation of audio-band frequency squeezed light at 1.34 μm

Feng Jin-Xia, 杜京师 DU Jing-shi, Jin Xiao-Li +2 more

Continuous variable (CV) audio-band frequency squeezed states at the fiber telecommunication wavelength is an important quantum resource for the practical applications based on optical fiber. As is well known, the optical power attenuation and phase diffusion effect of light at 1.3 μm in standard telecommunication fibres are low and small, respectively. The audio-band frequency squeezed light at 1.34 μm can be utilized to realize quantum precision measurement, such as quantum-enhanced sensing in the low-frequency range, laser interferometer for gravitational wave detection. In this paper, CV audio-band frequency vacuum squeezed states at 1.3 μm are experimentally generated by using a type-I degenerate optical parametric oscillator (DOPO) below the threshold. A home-made continuous-wave single-frequency dual-wavelength (671 nm and 1.34 μm) Nd:YVO4/LBO laser is used as a pump source for DOPO based on a type-I quasi-phase-matched periodically poled KTiOPO4 (PPKTP) crystal. Mode cleaners with a finesse of 400 and linewidth of 0.75 MHz are used to filter the noise of lasers at 671 nm and 1.34 μm, respectively. The intensity noises of the two lasers reach a shot noise level for analysis frequencies higher than 1.0 MHz and their phase noises reach shot noise level for analysis frequencies higher than 1.3 MHz, respectively. The low noise single-frequency 671 nm laser is utilized as a pump of the DOPO. The threshold power of the DOPO is 450 mW. In order to detect the audio-band frequency vacuum squeezed states, the power of local oscillator of a homodyne detector system is optimized to 60 μupW. Furthermore, the effect of common mode rejection ratio (CMRR) of detectors is discussed in detecting the audio-band frequency vacuum squeezed states. Improvement of CMRR of detectors is a good way to detect the audio-band frequency vacuum squeezed states effectively. When the phase matching temperature of PPKTP crystal is controlled at 53℃ by using a home-made temperature controller and the pump power is 95 mW, the vacuum squeezed states are generated at analysis frequency ranging from 8-100 kHz. A maximum measured squeeze of 5.0 dB is obtained at analysis frequency of 36 kHz. A 3.0 dB squeezed light is obtained at an audio-band frequency of 8 kHz.
