Phase-Sensitive Characterisation of Quantum Frequency Conversion by Spectral Interferometry

Abstract

We propose a scheme for phase-sensitive characterisation of coherent frequency conversion using the Green function formalism, for optimising nonlinear conversion in quantum and classical photonics experiments. We demonstrate this experimentally for Bragg-scattering four-wave mixing in photonic crystal fibre.

Phase-sensitive characterization of a quantum frequency converter by spectral interferometry

Mateusz J Olszewski, Kasper Hecht Alexander, Michael T M Woodley +3 more

We introduce an experimental technique for complete phase-sensitive characterization of arbitrary unitary spectral-temporal transformations of optical modes. Our method recovers the complex spectral transfer function, or Green's function, of a frequency converter by analyzing spectral interference in the response to a tunable bichromatic probe. We perform a proof-of-concept experiment on a frequency conversion module based on Bragg-scattering four-wave mixing in photonic crystal fiber. Our results validate our technique by recovering useful information in the phase of the Green's function, revealing the relative positions of regions of active frequency conversion and passive dispersive propagation within the module. Our work introduces a new approach to characterizing the performance of a variety of active devices with diverse applications in emerging quantum technologies.

Impulse response characterization of a quantum frequency converter

Kasper Alexander, Mateusz J. Olszewski, Michael T. M. Woodley +6 more

We present an experimental method for characterizing the (Green) cross-transfer functions of quantum frequency conversion (QFC) systems, which provide a complete spectral characterization of the underlying parametric interaction. We demonstrate the approach on a kilometer-scale fiber Bragg-scattering four-wave-mixing (BS-FWM) converter, retrieving its transfer functions directly from classical probe measurements. The reconstructed responses reveal clear departures from theory that we attribute primarily to longitudinal dispersion variations in the physical medium. Incorporating such variations in a numerical model yields quantitative agreement with experiment and accurately predicts single-photon conversion efficiencies measured independently in another experiment. The outlined method provides a practical route to characterizing and optimizing complex QFC systems using only classical probes, offering predictive insight directly relevant to applications in the quantum regime.

Coherent frequency conversion for quantum information processing

Stéphane Clemmen

Efficient frequency conversion is crucial for interfacing photons with a variety of quantum systems ranging from matter qubits (color centers, quantum dots, atoms), optical fibers, detectors, that often operate at widely different wavelengths. Frequency conversion is also a resource to process quantum information.1, 2 Parametric processes such as sum frequency generation (SFG) and Bragg scattering four wave mixing (BS-FWM) offer a good versatility for such frequency conversion. It is well understood that those nonlinear processes have to be strong enough and satisfy phase matching to achieve a high conversion efficiency. While it is enough to consider those two aspects for moderate conversion efficiency up to 50%, the analysis is a bit more complicated when targeting efficiencies closely approaching unity. We are reviewing the pitfall that must be avoided to indeed reach near unity frequency transduction.

Tunable phase-coherent FWM for quantum wavelength interconnects

Hao Zhang, Yang Xu, Linshan Sun +3 more

Quantum frequency conversion (QFC) plays a pivotal role in enabling coherent photonic interfaces across disparate quantum systems, serving as a foundation for scalable and interoperable quantum networks. Among various approaches, four-wave mixing (FWM) offers a promising path toward efficient, broadband QFC. In this work, we investigate the feasibility of phase-preserving frequency conversion, a necessary condition for coherent quantum state transfer, by characterizing the spectral phase mapping from input to output fields. We model nonlinear propagation through a gas-filled hollow-core capillary fiber, to demonstrate highly phase-coherent frequency conversion across a broad spectral range, including the infrared to ultraviolet, such as telecom (1550 nm) to visible (516 nm) and deep-UV (308 nm). We further examine how phase-mapping quality and conversion efficiency depend on key system parameters, including the intermediate pulse bandwidth and input pulse energy. Our results reveal optimal operating conditions for achieving future efficient and coherent QFC and provide valuable insights into the nonlinear dynamics underlying FWM-based transduction. These findings lay the groundwork for integrating heterogeneous quantum platforms across widely separated optical bands.
