Quantum detector tomography of high-dimensional multiplexed superconducting detectors

Abstract

We demonstrate quantum detector tomography of three different multiplexed SNSPDs, including a nonlinear detector of dimension > 103. We use this to extract efficiency, dark-count and cross-talk probability from just four elements of the reconstructed POVMs.

Quantum detector tomography of a high dynamic-range superconducting nanowire single-photon detector

Timon Schapeler, Jan Philipp Höpker, Tim J. Bartley

Abstract We demonstrate and verify quantum detector tomography of a superconducting nanowire single-photon detector (SNSPD) in a multiplexing scheme which permits measurement of up to 71 000 photons per input pulse. We reconstruct the positive operator valued measure (POVM) of this device in the low photon-number regime, and use the extracted parameters to show the POVMs spanning the whole dynamic range of the device. We verify this by finding the mean photon number of a bright state. Our work shows that a reliable quantum description of large-scale SNSPD devices is possible, and should be applicable to other multiplexing configurations.

Quantum detector tomography of a 2×2 multi-pixel array of superconducting nanowire single photon detectors

Timon Schapeler, Jan Philipp Höpker, Tim J. Bartley

We demonstrate quantum detector tomography of a commercial 2×2 array of superconducting nanowire single photon detectors. We show that detector-specific figures of merit including efficiency, dark-count and cross-talk probabilities can be directly extracted, without recourse to the underlying detector physics. These figures of merit are directly identified from just four elements of the reconstructed positive operator valued measure (POVM) of the device. We show that the values for efficiency and dark-count probability extracted by detector tomography show excellent agreement with independent measurements of these quantities, and we provide an intuitive operational definition for cross-talk probability. Finally, we show that parameters required for the reconstruction must be carefully chosen to avoid oversmoothing the data.

Quantum detector tomography of a time-multiplexed superconducting nanowire single-photon detector at telecom wavelengths

Chandra M. Natarajan, Lijian Zhang, Hendrik B. Coldenstrodt-Ronge +5 more

Superconducting nanowire single-photon detectors (SNSPDs) are widely used in telecom wavelength optical quantum information science applications. Quantum detector tomography allows the positive-operator-valued measure (POVM) of a single-photon detector to be determined. We use an all-fiber telecom wavelength detector tomography test bed to measure detector characteristics with respect to photon flux and polarization, and hence determine the POVM. We study the SNSPD both as a binary detector and in an 8-bin, fiber based, Time-Multiplexed (TM) configuration at repetition rates up to 4 MHz. The corresponding POVMs provide an accurate picture of the photon number resolving capability of the TM-SNSPD.

Tomography and state reconstruction with superconducting single-photon detectors

J. J. Renema, G. Frucci, M. J. A. de Dood +3 more

We investigate the performance of a single-element superconducting single-photon detector (SSPD) for quantum state reconstruction. We perform quantum state reconstruction, using the measured photon counting behavior of the detector. Standard quantum state reconstruction assumes a linear response; this simple model fails for SSPDs, which are known to show a nonlinear response intrinsic to the detection mechanism. We quantify the photon counting behavior of the SSPD by a sparsity-based detector tomography technique and use this to perform quantum state reconstruction of both thermal and coherent states. We find that the nonlinearities inherent in the detection process enhance the ability of the detector to do state reconstruction compared to a linear detector with similar efficiency for detecting single photons.
