Quantum-Secured Data Centre Interconnect in a field environment
Kaiwei Qiu, Jing Yan Haw, Hao Qin +3
In the evolving landscape of quantum technology, the increasing prominence of quantum computing poses a significant threat to the security of conventional public key infrastructure…
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…
Experimental vulnerability analysis of QKD based on attack ratings
Rupesh Kumar, Francesco Mazzoncini, Hao Qin +1
Inspired by the methodology used for classical cryptographic hardware, we consider the use of attack ratings in the context of QKD security evaluation. To illustrate the relevance…
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…
Homodyne-detector-blinding attack in continuous-variable quantum key distribution
Hao Qin, Rupesh Kumar, Vadim Makarov +1
We propose an efficient strategy to attack a continuous-variable quantum key distribution (CV-QKD) system, that we call homodyne detector blinding. This attack strategy takes advan…
Quantum hacking: saturation attack on practical continuous-variable quantum key distribution
Hao Qin, Rupesh Kumar, Romain Alléaume
We identify and study a new security loophole in continuous-variable quantum key distribution (CV-QKD) implementations, related to the imperfect linearity of the homodyne detector.…
Coexistence of continuous variable QKD with intense DWDM classical channels
Rupesh Kumar, Hao Qin, Romain Alléaume
We demonstrate experimentally the feasibility of continuous variable quantum key distribution (CV-QKD) in dense-wavelength-division multiplexing networks (DWDM), where QKD will typ…
