On the Equivalence between Classical Position Verification and Certified Randomness
Fatih Kaleoglu, Minzhao Liu, Kaushik Chakraborty +4
Gate-based quantum computers hold enormous potential to accelerate classically intractable computational tasks. Random circuit sampling (RCS) is the only known task that has been a…
Certified randomness using a trapped-ion quantum processor
Minzhao Liu, Ruslan Shaydulin, Pradeep Niroula +29
While quantum computers have the potential to perform a wide range of practically important tasks beyond the capabilities of classical computers, realizing this potential remains a…
Applications of Certified Randomness
Omar Amer, Shouvanik Chakrabarti, Kaushik Chakraborty +8
Certified randomness can be generated with untrusted remote quantum computers using multiple known protocols, one of which has been recently realized experimentally. Unlike the ran…
On the Relativistic Zero Knowledge Quantum Proofs of Knowledge
Kaiyan Shi, Kaushik Chakraborty, Wen Yu Kon +3
We initiate the study of relativistic zero-knowledge quantum proof of knowledge systems with classical communication, formally defining a number of useful concepts and constructing…
Quantum Authenticated Key Expansion with Key Recycling
Wen Yu Kon, Jefferson Chu, Kevin Han Yong Loh +5
Data privacy and authentication are two main security requirements for remote access and cloud services. While QKD has been explored to address data privacy concerns, oftentimes it…
100 Gbps Quantum-safe IPsec VPN Tunnels over 46 km Deployed Fiber
Obada Alia, Albert Huang, Huan Luo +3
We demonstrated for the first time quantum-safe high-speed 100 Gbps site-to-site IPsec tunnels secured using Quantum Key Distribution (QKD) technology. The demonstration was conduc…
