Abstract

We present our progress in the development of an integrated technology suitable for the photonic quantum information processing, showing the first autocorrelator based on two separated detectors integrated on top of the same ridge waveguide. An efficiency of ~1% at 1300 nm for both detectors and independent of the polarization of the incoming photons, is reported. This ultracompact device enables the on-chip measurement of the second-order correlation function g(2)(τ) . We will further discuss ongoing work on the integration of detectors with single-photon sources.

We demonstrate an integrated autocorrelator based on two superconducting single-photon detectors patterned on top of a GaAs ridge waveguide. This device enables the on-chip measurement of the second-order intensity correlation function g(2)(τ). A polarization-independent device quantum efficiency in the 1% range is reported, with a timing jitter of 88 ps at 1300 nm. g(2)(τ) measurements of continuous-wave and pulsed laser excitations are demonstrated with no measurable crosstalk within our measurement accuracy.

Waveguide superconducting single-photon autocorrelators for quantum photonic applications

Dondu Sahin, Alessandro Gaggero, G. Frucci +9 more

We report a novel component for integrated quantum photonic applications, a waveguide single-photon autocorrelator. It is based on two superconducting nanowire detectors patterned onto the same GaAs ridge waveguide. Combining the electrical output of the two detectors in a correlation card enables the measurement of the second-order correlation function g(2) (τ), which realizes the functionality of a Hanbury-Brown and Twiss experiment in a very compact integrated device. Each detector shows a polarization-independent quantum efficiency of ~0.5-1% at 1300 nm. This autocorrelator represents a key building block for quantum photonic integrated circuits including single-photon sources and linear optics.

Single-photon and photon-number-resolving detectors integrated with waveguide circuits

The integration of single-photon and photon-number-resolving detectors with single-photon sources and passive circuits is essential to realise fully-functional quantum photonic integrated circuits. We have recently demonstrated the first waveguide single photon detectors (WSPDs) [1] and a polarisation-independent on-chip autocorrelator for the measurement of the second-order correlation function g(2)(τ) [2], based on superconducting NbN nanowires on top of a GaAs/AlGaAs ridge waveguide.

Waveguide Nanowire Superconducting Single-Photon Detectors Fabricated on GaAs and the Study of Their Optical Properties

Dondu Sahin, Alessandro Gaggero, J. W. Weber +9 more

Quantum photonic integration is one of the leading approaches for enabling the implementation of quantum simulation and computing at the scale of tens to hundreds of photons. Quantum photonic integrated circuits require the monolithic integration of single-photon sources and passive circuit elements, such as waveguides and couplers, with single-photon detectors. A promising approach for on-chip single-photon detection is the use of superconducting nanowires on top of semiconductor waveguides. Here, we present state-of-the-art NbN films on GaAs for the realization of waveguide superconducting single-photon detectors, suitable for integration with sources and linear optical circuits. Based on the measured optical properties, we propose a new design which allows high absorptance for short nanowires in order to increase the integration density in a quantum photonic chip. Finally, we review recent results on integrated single-photon and photon-number-resolving detectors, and integrated autocorrelators.

Scaling waveguide-integrated superconducting nanowire single-photon detector solutions to large numbers of independent optical channels

Matthias Häußler, Robin Terhaar, Martin A. Wolff +11 more

Superconducting nanowire single-photon detectors are an enabling technology for modern quantum information science and are gaining attractiveness for the most demanding photon counting tasks in other fields. Embedding such detectors in photonic integrated circuits enables additional counting capabilities through nanophotonic functionalization. Here, we show how a scalable number of waveguide-integrated superconducting nanowire single-photon detectors can be interfaced with independent fiber optic channels on the same chip. Our plug-and-play detector package is hosted inside a compact and portable closed-cycle cryostat providing cryogenic signal amplification for up to 64 channels. We demonstrate state-of-the-art multi-channel photon counting performance with average system detection efficiency of (40.5 ± 9.4)% and dark count rate of (123 ± 34) Hz for 32 individually addressable detectors at minimal noise-equivalent power of (5.1 ± 1.2) · 10−18 W/Hz. Our detectors achieve timing jitter as low as 26 ps, which increases to (114 ± 17) ps for high-speed multi-channel operation using dedicated time-correlated single photon counting electronics. Our multi-channel single photon receiver offers exciting measurement capabilities for future quantum communication, remote sensing, and imaging applications.
