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…

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…

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…
Experimental Low-Latency Device-Independent Quantum Randomness
Yanbao Zhang, Lynden K. Shalm, Joshua C. Bienfang +10
Applications of randomness such as private key generation and public randomness beacons require small blocks of certified random bits on demand. Device-independent quantum random n…
Bounding the plausibility of physical theories in a device-independent setting via hypothesis testing
Yeong-Cherng Liang, Yanbao Zhang
The device-independent approach to physics is one where conclusions about physical systems (and hence of Nature) are drawn directly and solely from the observed correlations betwee…
Certifying Quantum Randomness by Probability Estimation
Yanbao Zhang, Emanuel Knill, Peter Bierhorst
We introduce probability estimation, a broadly applicable framework to certify randomness in a finite sequence of measurement results without assuming that these results are indepe…
