Abstract

Maintenance-free wavelength-division-multiplexing quantum key distribution for 30 days was achieved through a 22-km field fiber. Using polarization-independent interferometers and stabilization techniques, we attained a quantum bit error rate as low as 1.70% and an estimated secure key rate as high as 112.4 kbps for a record-breaking 291.3 Gbits of estimated secure keys accumulated over an uninterrupted operation period.

1. Introduction

Many contemporary cryptographic protocols are implemented by computer algorithms based on the assumption that certain mathematical problems are extraordinarily difficult to solve using current computer resources and well-known attacks. Such algorithmic cryptography is not provably secure and is vulnerable to off-line attacks that can occur long after a secret message has been sent. One well known scheme of a provably secure protocol is Vernam's one-time pad (OTP). In this protocol, a truly random key whose length is the same as that of a plain text is shared between the legitimate sender and receiver. Bit wise exclusive OR is calculated in encryption and decryption. And shared keys are used only once. Quantum key distribution (QKD) provides a method of sharing such a truly random key on demand between two users through a physical channel of photon transmission. Its security can be proven against eavesdroppers with unbounded abilities.

Although QKD technology is now in practical use, its speed and distance remain limited. Commercial products typically operate at key rates of about a few kbps over field fibers a few tens of km long [13]. They are often therefore not used in the OTP mode but in a hybrid mode combined with contemporary cryptographic protocols such as the scheme that refreshes the seed keys for symmetric key encryption [4, 5]. As for QKD systems in laboratories, key rates typically reach a few hundred kbps over 40–50-km field fibers [57], thus enabling the support of OTP encryption of video data. However, increasing the key rate only with single-channel QKD results in a bottleneck due to the speed limit of single-photon detectors, whose novel types operate in the GHz range [811], and further improvements are not easy. Our recently developed wavelength-division multiplexing (WDM) QKD system [12, 13] provides a flexible solution to support a variety of applications including secure voice transmission and real-time secure TV conferencing with OTP encryption.

Currently, the main need in terms of putting state-of-the-art QKD technologies to practical use is quality assurance, especially for long-term maintenance-free operation. The high-speed QKD specifications mentioned above have been recorded only for two weeks at the longest [14], and their stability is not yet sufficient to be certified for practical services in commercial environments. The stability also directly affects the certification of QKD security. An experimental guarantee of stable key generation with a low enough quantum bit error rate (QBER) for a long period is a prerequisite for the quality assurance of any QKD system.

In this work, we report on maintenance-free, continuous key generation over 30 days using two quantum channels through a 22-km field fiber. Our WDM-QKD system has polarization-independent interferometers. Obviously, the decoy state is necessary for realizing reasonable performance in a contemporary BB84 QKD system. The intensity of the decoy state should be optimally chosen, and carefully stabilized. However the intensity fluctuation is more or less inevitable in practical environment. The security analysis taking into account such a fluctuation has not necessarily been established yet. Therefore we focused on evaluating the stability of the QKD system and transmission channel using sifted key rates and QBERs without decoy states as the first step of long-term reliable operation. Moreover, we develop a stabilization system against an elastic quantum channel and a drift of optical components due to air temperature change in the operating room. We achieved stable sifted key generation higher than 400 kbps in total and a QBER of 1.61% and 1.86% for each channel on average for 30 days. In addition, our system can operate with the decoy state protocol, hence we report estimated secure keys which are distilled with assuming the three-state decoy protocol.

2. WDM-QKD system

In previous works, we established a compact optical transmission block consisting of planar lightwave circuits (PLCs), which are superior in mass productivity, reliability, polarization-insensitivity, and controllability [1517]. Figure 1 shows a simplified functional diagram of the optical system. In the transmitter (Alice), a PLC-based 2 × 2 asymmetric Mach-Zehnder interferometer (AMZI) converts an optical pulse from a laser diode (LD) driven at 1.24 GHz into a pair of pulses with a time delay of 400 ps. A dual-drive Mach-Zehnder modulator used as an encoder puts data and basis information on the pair for preparing the time-bin signal in phase-time coding (see Fig. 1 inset). Then, a variable optical attenuator (VOA) attenuates the power of the pair to 0.5 photons. The quantum signal is combined with the clock signal for precise and automatic synchronization by using a WDM coupler and is transmitted through the same fiber. We minimize the power of clock signal (1570.42nm) around −20dBm to decrease Stokes and anti-Stokes emissions. Combining with the WDM couplers, there is no influence to quantum signals. In the receiver (Bob), a PLC-based 2 × 4 AMZI, which is totally passive, followed by four photon detectors, decodes the time-bin signal. The delay tuning of the AMZIs is made with the temperature controller (TC) within an accuracy of 0.01 K to attain a total extinction ratio as high as 20dB [15].

These technologies can be optimized to implement our GHz-clocked WDM-QKD system, which can potentially handle up to eight wavelength channels allocated on the ITU-T 100-GHz grid from 1545.3 to 1550.9 nm. One more important technology is required to make the WDM-QKD system cost-effective, which is a colorless interferometer consisting of the PLC AMZI whose temperature is controlled for polarization-independent interference and a technique of phase mismatch compensation for every wavelength. Figure 2 shows our WDM-QKD system. In the transmitter, optical pulses emitted by LDs are multiplexed with a WDM coupler. The multiplexed pulses pass through the PLC AMZI and are converted into the time-bin signals. They are then demultiplexed and each wavelength component is encoded with bit data and basis information by phase and amplitude modulation as denoted by ϕA(λn). Additional phase modulators denoted by Δθ(λn) follow to compensate for the phase mismatches. The receiver decodes the signals almost in the reverse manner. This colorless interferometer with the PLCs can be used to create a WDM-QKD with reduced system size, cost, and control complexity [12, 13].

Optical components, including the colorless interferometer and other elements required of the QKD system such as synchronization and key distillation, are mounted onto the advanced telecom computing architecture (ATCA) chassis and a 19-inch rack. Our WDM-QKD system is designed for a secure key rate of almost 1 Mbps over a 10-dB loss channel when eight wavelength channels are fully operational.

3. Stabilization techniques

Even if we set parameters to the optimal values at the beginning of operation, the key generation performance would degrade after a certain amount of time due to temperature change of the transmission fiber or location, drift of power-supply voltage, and temporal change of devices. For reliable long-term operation, we have to suppress these effects. For example, polarization variation in the transmission fiber is critical to the extinction ratio of the conventional interferometer and dramatically increases the QBER within a short period of time. The polarization variation could be solved by the polarization-independent interferometer based on the PLC technique [15] mentioned above. As another example, fiber expansion delays the optimal detection timing of photon detectors. In our system, the delay of 50 ps causes degradation of the photon count rate to around 80%. We therefore optimize the detection timing with an accuracy of 12.5 ps. To improve the reliability of the QKD system, such optimizations have to be done for various components constantly, so we have added the following stabilization controls:

  • - Detection timing of the photon detectors
  • - Bias voltage of the encoding modulator
  • - Temperature of the PLC interferometer
  • - Amplitude of the phase compensation modulator

The stabilization procedure is as follows: first, control software retrieves the key generation performance (photon count rates or QBERs) from the receiver (Bob, Fig. 2). Next, the software varies the operating point of one of the device components listed above to be slightly different from the present parameter and monitors the key generation performance again to see the results. Finally, the software compares the results and chooses better parameters. Then it goes to the other component and runs similar processing. After tuning all the components, it repeats from the start. The period of this cycle is approximately three minutes. This procedure is executed in parallel with the key generation. This control scheme keeps each parameter optimal and results in stable key generation performance even if the environmental or component conditions fluctuate.

4. Long-term field demonstration

We demonstrated our 2-channel WDM-QKD for the BB84 protocol using two wavelengths, λ1 (1547.72 nm) and λ2 (1550.92 nm). By using appropriate WDM filters, the cross-talk of these signals did not affect each other. The transmission channel is a 22-km field installed single-mode fiber in a loop-back configuration. More than 95% of the channel is in an aerial fiber over poles. The total loss is 12.6dB. Figure 3 shows a typical variation of fiber transmission characteristics in terms of polarization drift. Polarization fluctuates all the time, although it is more apparent during the day. In the receiver, two avalanche photodiode (APD) systems [11] were used. The quantum efficiency and dark count rate were 10–15% and 1–2 k count/s.

Figures 4(a) and 4(b) plot the QBERs, the sifted key rates and estimated secure key rates for the two channels, for 30 days respectively. Secure key rates are calculated assuming low-density parity check (LDPC) error correction code and the three-state decoy protocol for the privacy amplification. We assume a LDPC code applicable up to the error rate of 3% with coding rate of 0.77, which we have already built separately. As to the privacy amplification, we assume a three-state decoy protocol which is installed in our QKD system. The finite-length effect is taken into account based on the analysis by Hayashi [18]. Average photon number of signal is 0.5 while 0.2 and vacuum are used for decoy states. These decoy pulses are shuffled at rates of 6% and 4% respectively. From our preliminary experiment, it is known that the signal intensity fluctuates by up to +/− 7% in a long period. Since it is a challenging issue to reflect this fluctuation on the secure key rate, we estimate it assuming decoy state protocol without the intensity fluctuation. The QKD performance of each channel is summarized in Table 1. Over consecutive 30 days, sifted key generation at an average rate of 483.3 kbps in total, and an averaged QBER of 1.70% were achieved in maintenance-free operation.

Table 1. Key generation performance over 30 days.

In Fig. 4(b), the sifted key rate and the secure key rate gradually decreased. This is because the operation temperature of the APDs in λ2 had been raised from–40°C to –36°C during the 30 days of operation due to degradation of the APD’s package. This increase in temperature leads to an increase in the breakdown voltage of the APD. In this trial, the APDs were used at a constant bias voltage. Therefore, the detection efficiency of the APD in λ2 decreased, which led to the decline of the sifted key rate.

In Table 2, we compare the results of recent long-term field operations. The total number of estimated secure bits distributed over the 22-km installed fiber for a 30-day uninterrupted duration of continuous operation amounts to 291.3 Gbits. To the best of our knowledge, this is the largest in previous works reported thus far, such as the 70 Gbits over a 3.7-km installed fiber for 327 days (SQ3 link from 3 Sept. 2009 to 26 July 2010) by Stucki et al. [5] and the 63.3 Gbits by Dynes et al. over a 45-km installed fiber for 60 hours [19].

5. Conclusion

We have developed a high-speed QKD system based on the scalable WDM technique with polarization-independent interferometers and stabilization control of various parameters. By driving the system with two channels, we achieved 30 days of maintenance-free continuous key generation with QBERs of 1.70% and an estimated secure key rate of 112.4 kbps through a 22-km field fiber with 12.6-dB loss. We compared total secure keys distributed in continuous operation to quantify the quality of long-term QKD operation. Our results amounted to a record-breaking 291.3 Gbits.

However, we have to continue discussions on influence of stabilities in components. For example, the deviations of intensities in decoy pulses should be considered. Because those fluctuations will produce estimate error in distillation process and decrease secure key rates. Since the theory of the decoy state explicitly uses the information of photon number distributions of the decoy states and the signal, the fluctuations of the photon number distributions may lead to failure distillation of the secure key. Therefore, the measurement of fluctuations of distribution through long-term operation contributes to establish more rigorous security analysis and standardization of QKD systems.
