Boosting end-to-end entanglement fidelity in quantum repeater networks via hybridized strategies
Poramet Pathumsoot, Theerapat Tansuwannont, Naphan Benchasattabuse +5
Quantum networks are expected to enhance distributed quantum computing and quantum communication over long distances while providing security dependent upon physical effects rather…
Preparing a commercial quantum key distribution system for certification against implementation loopholes
Vadim Makarov, Alexey Abrikosov, Poompong Chaiwongkhot +9
A commercial quantum key distribution (QKD) system needs to be formally certified to enable its wide deployment. The certification should include the system's robustness against kn…
Hybrid Error-Management Strategies in Quantum Repeater Networks
Poramet Pathumsoot, Theerapat Tansuwannont, Naphan Benchasattabuse +5
A quantum network is expected to enhance distributed quantum computing and quantum communication over a long distance while providing unconditional security. As quantum entanglemen…
Protecting fiber-optic quantum key distribution sources against light-injection attacks
Anastasiya Ponosova, Daria Ruzhitskaya, Poompong Chaiwongkhot +3
A well-protected and characterised source in a quantum key distribution system is needed for its security. Unfortunately, the source is vulnerable to light-injection attacks, such…
Hybrid Quantum-Classical Algorithms for Loan Collection Optimization with Loan Loss Provisions
Jirawat Tangpanitanon, Jirawat Saiphet, Pantita Palittapongarnpim +6
Banks are required to set aside funds in their income statement, known as a loan loss provision (LLP), to account for potential loan defaults and expenses. By treating the LLP as a…
Faking photon number on a transition-edge sensor
Poompong Chaiwongkhot, Jiaqiang Zhong, Anqi Huang +3
We study potential security vulnerabilities of a single-photon detector based on superconducting transition-edge sensor. In a simple experiment, we show that an adversary could fak…
Enhancing secure key rates of satellite QKD using a quantum dot single-photon source
Poompong Chaiwongkhot, Sara Hosseini, Arash Ahmadi +6
Global quantum secure communication can be achieved using quantum key distribution (QKD) with orbiting satellites. Established techniques use attenuated lasers as weak coherent pul…
An approach for security evaluation and certification of a complete quantum communication system
Shihan Sajeed, Poompong Chaiwongkhot, Anqi Huang +8
Although quantum communication systems are being deployed on a global scale, their realistic security certification is not yet available. Here we present a security evaluation and…
Laser seeding attack in quantum key distribution
Anqi Huang, Álvaro Navarrete, Shi-Hai Sun +3
Quantum key distribution (QKD) based on the laws of quantum physics allows the secure distribution of secret keys over an insecure channel. Unfortunately, imperfect implementations…
Eavesdropper's ability to attack a free-space quantum-key-distribution receiver in atmospheric turbulence
Poompong Chaiwongkhot, Katanya B. Kuntz, Yanbao Zhang +6
The ability of an eavesdropper (Eve) to perform an intercept-resend attack on a free-space quantum key distribution (QKD) receiver by precisely controlling the incidence angle of a…
Eavesdropping and countermeasures for backflash side channel in quantum cryptography
Paulo Vinicius Pereira Pinheiro, Poompong Chaiwongkhot, Shihan Sajeed +5
Quantum key distribution (QKD) promises information theoretic secure key as long as the device performs as assumed in the theoretical model. One of the assumptions is an absence of…
Finite-key-size effect in commercial plug-and-play QKD system
Poompong Chaiwongkhot, Shihan Sajeed, Lars Lydersen +1
A security evaluation against the finite-key-size effect was performed for a commercial plug-and-play quantum key distribution (QKD) system. We demonstrate the ability of an eavesd…
Testing random-detector-efficiency countermeasure in a commercial system reveals a breakable unrealistic assumption
Anqi Huang, Shihan Sajeed, Poompong Chaiwongkhot +3
In the last decade, efforts have been made to reconcile theoretical security with realistic imperfect implementations of quantum key distribution (QKD). Implementable countermeasur…
Creation of backdoors in quantum communications via laser damage
Vadim Makarov, Jean-Philippe Bourgoin, Poompong Chaiwongkhot +7
Practical quantum communication (QC) protocols are assumed to be secure provided implemented devices are properly characterized and all known side channels are closed. We show that…
Security loophole in free-space quantum key distribution due to spatial-mode detector-efficiency mismatch
Shihan Sajeed, Poompong Chaiwongkhot, Jean-Philippe Bourgoin +3
In free-space quantum key distribution (QKD), the sensitivity of the receiver's detector channels may depend differently on the spatial mode of incoming photons. Consequently, an a…
