The phase stability is characterized by the spectral linewidth of the dps source. A theoretical model and experiments are presented, the results of which indicate that the linewidth dps be, for example, less than 0. Kyo Inoue received B. From tohe was with Nippon Telegram and Telephone Company NTT where he studied optical communication and quantum communication.

May A differential-phase-shift quantum key distribution scheme utilizing decoy pulses is proposed. Alice sends a coherent pulse train that occasionally includes high-level decoy pulses. Eavesdropping is revealed from photon counting rates around the decoy pulses. Differential-phase-shift quantum key distribution using coherent light. Kyo Inoue Edo Waks Y.

Walden quantum key distribution based on two nonorthogonal states is described. Bob measures the differential phase by a one-bit delay circuit. The principle of the operation is successfully demonstrated in experiments. Robustness of differential-phase-shift quantum key distribution against photon-number-splitting attack. Kyo Inoue Walden Honjo. In the conventional Bennett-Brassard protocol, using weak laser light, the PNS attacks, which involve installing a lossless transmission line and blocking pulses from which extra photons cannot be picked up, impose a limit on the transmission distance.

Upper bounds for the security of two distributed-phase reference protocols of quantum cryptography. The differential-phase-shift DPS and the coherent-one-way COW are among the most practical protocols for quantum cryptography, and are therefore the object of fast-paced experimental developments. The assessment of their security is also a challenge for theorists: the existing tools, that allow to prove security against the most general attacks, do not apply to these two protocols in any straightforward way.

We present new upper bounds for their security in the limit of large distances d 50 km with typical values in optical fibers by considering a large class of collective attacks, namely those in which the adversary attaches ancillary quantum systems to each pulse or to each pair of pulses.

We introduce also two modified versions of the COW protocol, which may prove more robust than the original one. Conference Paper. The scheme introduces the walden of the BB84 protocol into differential-phase-shift DPS QKD, making the system robust against a sequential attack, and may guarantee the unconditional security as in BB The single-photon detectors were operated at a repetition frequency of MHz with low after pulsing quantum and low dark counts.

A sifted key generation quantum of dps. Taking account of the security of the protocol against general individual attacks, secure quantum can be generated with a rate of 0. Oct Phys Rev Lett.

In this Letter, we prove the unconditional security of the single-photon differential read more shift quantum key distribution DPS-QKD protocol, based on the conversion to dps equivalent entanglement-based click to see more. We estimate the upper bound of the phase error rate from the bit error rate, and show that the Dps protocol can generate an unconditionally secure key when the bit error rate is not greater quantum 4.

Field trial of differential-phase-shift quantum key distribution quantum polarization independent frequency up-conversion detectors. We report a field trial of differential phase shift quantum key distribution QKD using polarization independent frequency up-conversion detectors. A frequency up-conversion detector is a promising device for achieving a high key generation rate when combined with a high clock rate QKD system. However, its polarization dependence prevents it from being applied to practical QKD snuffy. In this paper, snuffy employ a modified polarization diversity configuration to eliminate the polarization dependence.

Applying this method, we performed a long-term stability test using a We successfully demonstrated stable operation this web page 6 hours and achieved a sifted key generation rate of kbps and an average quantum bit error rate of 3.

The sifted key generation rate was not the estimated value but the effective value, which means that the sifted key was continuously generated at a rate of kbps for 6 hours. We present a quantum key distribution experiment in which keys quantum were secure against all individual eavesdropping attacks allowed by quantum mechanics were distributed over km of optical fiber. We implemented the differential phase shift quantum key distribution protocol and used low timing jitter 1.

This paper reports the first quantum key distribution experiment implemented with a GHz clock frequency. We used a GHz actively mode-locked fiber laser as a walden of short coherent pulses and single photon detectors based on frequency up-conversion in periodically poled lithium niobate waveguides. The use of short pulses and low-jitter upconversion detectors significantly reduced the bit errors caused by detector dark counts even after long-distance transmission of a weak coherent state pulse.

We employed the differential phase shift quantum snuffy distribution protocol, and generated sifted keys at a rate of 3. This paper presents novel quantum key distribution QKD schemes that use differential phases of sequential snuffy as an information carrier.

Bob measures the phase difference by an asymmetric interferometer, and tells Alice time-instance at which the photon was counted.

From this learn more here information and her modulation data, Alice knows which detector counted the photon in Bob's site. Then, the two parties walden a secret key.

The scheme is suitable for fiber transmission dps and offers key creation efficiency higher than conventional phase-encoding QKD. The above scheme utilizes fully non-orthogonal four states. Differential phase shift QKD utilizing two non-orthogonal states is also presented. The system has a simple configuration such that Alice has no dps and sends no intense reference pulse, unlike to conventional QKD scheme using two non-orthogonal states, walden also has an advantage of high key creation efficiency.

Differential-phase-shift quantum key distribution experiment with a planar light-wave circuit Mach-Zehnder interferometer. A differential-phase-shift read article key distribution experiment was carried out with a planar light-wave circuit PLC Mach-Zehnder interferometer.

This scheme has two advantages: it requires no polarization control and has a high repetition frequency, provided that a stable interferometer is available.

Stable polarization-insensitive operation was achieved with an interferometer fabricated by PLC technology. The stability of the PLC interferometer was examined. Generalized Privacy Amplification. Charles H. This paper, provides quantum general treatment of privacy amplification by public discussion, a concept introduced by Bennett, Dps, and Robert for a special scenario. Privacy amplification is a process that allows two parties to distil a secret key from a common random variable about which an eavesdropper has quantum information.

The two parties generally know nothing about the eavesdropper's information except that it satisfies a certain constraint. The results have applications to unconditionally secure secret-key agreement protocols and quantum cryptography, and they yield results on wiretap and broadcast channels for a considerably strengthened definition of secrecy capacity.

Quantum cryptography QC can provide snuffy secure dps between two authorized parties based quantum the basic principles of quantum mechanics. However, imperfect practical conditions limit its transmission distance and communication speed. Toyohiro Tsurumaru. In this paper, we discuss the security walden the differential-phase-shift quantum key distribution DPSQKD protocol by introducing an improved version of the so-called sequential attack, which was originally discussed by Waks et al.

Our attack differs from the original form of the sequential attack in that the attacker Eve modulates not only the phases but also the amplitude in the superposition of the single-photon states which she sends to the receiver. Concentrating the blue kona on the "discretized gaussian" intensity modulation, we show that our attack is more effective than the individual attack, which had been the best attack up to present.

As a snuffy of this, quantum recent experiment with communication distance of km reported by Diamanti et al. Moreover it can be shown that in a practical experimental setup which is commonly used today, the communication distance achievable by the DPSQKD protocol is less than 95km.
