Quantum Two-Way Protocol Beyond Superdense Coding: Joint Transfer of Data and Entanglement

January 10, 2025Kristian S. Jensen, Lorenzo Valentini, René B. Christensen, Marco Chiani, Petar PopovskiQuantum InternetEncoding, Metadata, Photonics, Proposals, Protocols, Quantum channels, Quantum entanglement, Qubit, Repeaters, Throughput

In this article, we introduce a generalization of one-way superdense coding to two-way communication protocols for transmitting classical bits by using entangled quantum pairs. The proposed protocol jointly addresses the provision of entangled pairs and superdense coding, introducing an integrated approach for managing entanglement within the communication protocol. To assess the performance of the proposed […]

Fault-Tolerant One-Way Noiseless Amplification for Microwave Bosonic Quantum Information Processing

August 7, 2024Hany Khalifa, Riku Jäntti, Gheorghe Sorin ParaoanuQuantum InternetComputational modeling, Logic gates, Microwave amplifiers, Photonics, Propagation losses, Quantum entanglement, Qubit

Microwave quantum information networks require reliable transmission of single-photon propagating modes over lossy channels. In this article, we propose a microwave noiseless linear amplifier (NLA) suitable to circumvent the losses incurred by a flying photon undergoing an amplitude damping channel (ADC). The proposed model is constructed by engineering a simple 1-D four-node cluster state. Contrary […]

Detectors capable of resolving the number of photons are essential in many applications, ranging from classic photonics to quantum optics and quantum communication. In particular, photon-number-resolving detectors based on arrays of superconducting nanostrips can offer a high detection efficiency, a low dark count rate, and a recovery time of a few nanoseconds. In this work, […]

The light’s image is the primary source of information carrier in nature. Indeed, a single photon’s image possesses a vast information capacity that can be harnessed for quantum information processing. Our scheme for implementing quantum information processing on a discretized photon wavefront via universal multiport processors employs a class of quantum Fourier optical systems composed […]

Rateless Protograph LDPC Codes for Quantum Key Distribution

February 2, 2024Alberto Tarable, Rudi Paolo Paganelli, Marco Ferrari,Quantum InternetCodes, Parity check codes, Photonics, Protocols, Quantum channels, Quantum key distribution, Qubit

Information reconciliation (IR) is a key step in quantum key distribution (QKD). In recent years, blind reconciliation based on low-density parity-check (LDPC) codes has replaced Cascade as a standard de facto since it guarantees efficient IR without a priori quantum bit error rate estimation and with limited interactivity between the parties, which is essential in […]

Time Binning Method for Nonpulsed Sources Characterization With a Superconducting Photon Number Resolving Detector

September 19, 2023Pasquale ErcolanoQuantum EngineeringDetectors, High-temperature superconductors, Light sources, Photonics, Recording, Superconducting integrated circuits, Superconducting photodetectors

Photon number resolving detectors find space in many fields, such as quantum optics, boson sampling, and fluorescence spectroscopy. In particular, the reconstruction of the input photon distribution is essential in quantum communications to detect photon-number-splitting attacks. In this work, we discuss the operation configurations of a photon number resolving detector based on superconducting nanostrips at […]

MIMO Terahertz Quantum Key Distribution Under Restricted Eavesdropping

June 14, 2023Neel Kanth KunduQuantum InformationEavesdropping, MIMO communication, Photonics, Quantum computing, Quantum key distribution, Security, Wireless communication

Quantum key distribution (QKD) can provide unconditional security to next-generation communication networks guaranteed by the laws of quantum physics. This article studies the secret key rate (SKR) of a continuous variable QKD (CV-QKD) system using multiple-input multiple-output (MIMO) transmission and operating at terahertz (THz) frequencies. Distinct from previous works, we consider a practical “restricted” eavesdropping […]
