Constraints on recovering quantum information after erasure
Mohammad A. Alhejji, Noah Lordi, Omkar Baraskar +2
Suppose that we encode quantum information into physical carriers. With what probabilities can we perfectly recover the quantum information after sets of carriers have been e…
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 +17
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…
