An efficient method for spot-checking quantum properties with sequential trials
Yanbao Zhang, Akshay Seshadri, Emanuel Knill
In practical situations, the reliability of quantum resources can be compromised due to complex generation processes or adversarial manipulations during transmission. Consequently,…
Quantum Position Verification with Remote Untrusted Devices
Gautam A. Kavuri, Yanbao Zhang, Abigail R. Gookin +16
Position information underpins many modern technologies, from navigation and timing to authentication and critical infrastructure. However, classical methods of proving that inform…
Traceable random numbers from a nonlocal quantum advantage
Gautam A. Kavuri, Jasper Palfree, Dileep V. Reddy +20
The unpredictability of random numbers is fundamental to both digital security and applications that fairly distribute resources. However, existing random number generators have li…
Security proof of practical quantum key distribution with detection-efficiency mismatch
Yanbao Zhang, Patrick J. Coles, Adam Winick +2
Quantum key distribution (QKD) protocols with threshold detectors are driving high-performance QKD demonstrations. The corresponding security proofs usually assume that all physica…
Tsirelson Polytopes and Randomness Generation
Peter Bierhorst, Yanbao Zhang
We classify the extreme points of a polytope of probability distributions in the (2,2,2) CHSH-Bell setting that is induced by a single Tsirelson bound. We do the same for a class o…
Experimental Realization of Device-Independent Quantum Randomness Expansion
Ming-Han Li, Xingjian Zhang, Wen-Zhao Liu +12
Randomness expansion where one generates a longer sequence of random numbers from a short one is viable in quantum mechanics but not allowed classically. Device-independent quantum…
