Experimental Demonstration of Free-Space Unidimensional Continuous-Variable Quantum Key Distribution Under High Detector Noise
Rachita Nandan, Jayanth Ramakrishnan, Shashi Prabhakar +1
Continuous-variable quantum key distribution (CV-QKD), which uses quadratures of the electromagnetic field, enables practical quantum communication using standard telecommunication…
Strengthening the No-Go Theorem for QRNGs
Vardaan Mongia, Abhishek Kumar, Shashi Prabhakar +1
Quantum random numbers are essential for security against quantum algorithms. Randomness as a beacon is a service being provided for companies and governments to upgrade their secu…
Enhancing key rates of QKD protocol by Coincidence Detection
Tanya Sharma, Rutvij Bhavsar, Jayanth Ramakrishnan +4
In theory, quantum key distribution (QKD) provides unconditional security; however, its practical implementations are susceptible to exploitable vulnerabilities. This investigation…
Investigating a Device Independence Quantum Random Number Generation
Vardaan Mongia, Abhishek Kumar, Shashi Prabhakar +2
Quantum random number generation (QRNG) is a resource that is a necessity in the field of cryptography. However, its certification has been challenging. In this article, we certify…
