Self-testing randomness from a nuclear spin system
Xing Chen, Minsik Kwon, Vadim Vorobyov +2
Randomness is a very important resource for cryptography, algorithms, and scientific simulations. Since all classical processes are considered to be intrinsically deterministic, we…
Single Photon Randomness based on a Defect Center in Diamond
Xing Chen, Johannes Greiner, Jörg Wrachtrup +1
The prototype of a quantum random number generator is a single photon which impinges onto a beam splitter and is then detected by single photon detectors at one of the two output p…
Certified Randomness from Remote State Preparation Dimension Witness
Xing Chen, Kai Redeker, Robert Garthoff +3
Randomness in Bell test data can be device-independently certified by Bell's theorem without placing assumptions about the experimental devices. The device-independent randomness h…
All entangled states can generate certified randomness
Xing Chen
Random number has many applications, it plays an important role in quantum information processing. It's not difficult to generate true random numbers, the main difficulty is how to…
Entanglement witness game
Xing Chen, Xueyuan Hu, D. L. Zhou
Motivated by Buscemi's semi-quantum nonlocal game [PRL 108, 200401(2012)], We propose an entanglement witness game, a quantum game based on entanglement witness. Similar as the sem…
Basis entropy: A useful physical quantity about projective measurement
Xing Chen
Projective measurement can increase the entropy of a state , the increased entropy is not only up to the basis of projective measurement, but also has something to do with the p…
