Abstract

A new strategy of iterative quantum receivers with photon-number-resolving detectors is proposed to discriminate coherent states. The iterative quantum receiver provides a bit error rate closer to the Helstrom limit when compared with a recently proposed non-iterative quantum receiver. Moreover, the proposed iterative receiver is robust against various imperfections, such as mode mismatch, non-ideal quantum efficiency and dark counts. The simulation results indicate that the iterative receiver is capable of achieving 2.16 dB improvement upon the standard quantum limit, leaving only 0.65 dB from the Helstrom limit. Besides, with Turbo encoder and decoder, the iterative receiver gives about 1.46 dB improvement over the conventional non-iterative quantum receiver and approaches the equivalent Helstrom limit.

Soft Iterative Quantum Receivers Approaching the Helstrom Limit Using Realistic Quantum Devices

One of the most crucial challenges in quantum communication is the discrimination of the non-orthogonal coherent states approaching the Helstrom limit. In this paper, a soft iterative quantum receiver is derived for discriminating among the coherent states. The receivers employing the iterative strategy for optimizing the feedback measurement are capable of operating closer to the theoretical error probability limit, actuating about 1.05 dB improvement over a recent proposed quantum receiver. The iterative quantum receivers achieve excellent performance despite using a reduced number of feedback measurement steps. Monte Carlo simulations are performed for quantifying the influence of practical quantum-domain impairments. These results suggest that iterative detection offers substantial robustness against many imperfections degrading realistic experimental implementation.

Hybrid near-optimum binary receiver with realistic photon-number-resolving detectors

Michele N. Notarnicola, Matteo G. A. Paris, Stefano Olivares

We propose a near-optimum receiver for the discrimination of binary phase-shift-keyed coherent states employing photon-number-resolving detectors. The receiver exploits a discrimination strategy based on both so-called homodyne-like and direct detection, thus resulting in a hybrid scheme. We analyze the performance and robustness of the proposed scheme under realistic conditions, namely, in the presence of inefficient detection and dark counts. We show that the present hybrid setup is near- optimum and beats both the standard quantum limit and the performance of the Kennedy receiver.

Quantum receivers with squeezing and photon-number-resolving detectors for M -ary coherent state discrimination

Shuro Izumi, Masahiro Takeoka, Kazuhiro Ema +1 more

We propose quantum receivers with optical squeezing and photon-number-resolving detectors (PNRDs) for the near-optimal discrimination of quaternary phase-shift-keyed coherent state signals. The basic scheme is similar to the previous proposals [e.g., Izumi et al., Phys. Rev. A 86, 042328 (2012)] in which displacement operations, on-off detectors, and electrical feedforward operations were used. Here we study two types of receivers, one of which installs optical squeezings and the other uses PNRDs instead of on-off detectors. We show that both receivers can attain lower error rates than that in the previous scheme. In particular, we show the PNRD-based receiver has a significant gain when the ratio between the mean photon number of the signal and the number of the feedforward steps is relatively high, in other words, when the probability of detecting two or more photons at each detector is not negligible. Moreover, we show that the PNRD-based receiver can suppress the errors due to dark counts, which the receiver with the on-off detector cannot do with a small number of feedforwards.

Discrimination of optical coherent states using a photon number resolving detector

Wittmann, C., Ulrik L. Andersen, Gerd Leuchs

The discrimination of non-orthogonal quantum states with reduced or without errors is a fundamental task in quantum measurement theory. In this work, we investigate a quantum measurement strategy capable of discriminating two coherent states probabilistically with significantly smaller error probabilities than can be obtained using non-probabilistic state discrimination. We find that appropriate postselection of the measurement data of a photon number resolving detector can be used to discriminate two coherent states with small error probability. We compare our new receiver to an optimal intermediate measurement between minimum error discrimination and unambiguous state discrimination.
