Consecutive Measurement Tradeoffs in Quantum Cryptography
Chen-Xun Weng, Minglong Qin, Yanglin Hu +1
Measuring a quantum system can reveal information while disturbing its state. Consequently, the probabilities of obtaining desired outcomes in individual measurements constrain the…
Sample Optimal and Memory Efficient Quantum State Tomography
Yanglin Hu, Enrique Cervero-Martín, Elias Theil +2
Quantum state tomography is the fundamental physical task of learning a complete classical description of an unknown state of a quantum system given coherent access to many identic…
Device independent security of quantum key distribution from monogamy-of-entanglement games
Enrique Cervero-Martín, Marco Tomamichel
We analyse two party non-local games whose predicate requires Alice and Bob to generate matching bits, and their three party extensions where a third player receives all inputs and…
Practical relativistic bit commitment
Tommaso Lunghi, Jędrzej Kaniewski, Felix Bussieres +4
Bit commitment is a fundamental cryptographic primitive in which Alice wishes to commit a secret bit to Bob. Perfectly secure bit commitment between two mistrustful parties is impo…
Experimental bit commitment based on quantum communication and special relativity
T. Lunghi, J. Kaniewski, F. Bussieres +6
Bit commitment is a fundamental cryptographic primitive in which Bob wishes to commit a secret bit to Alice. Perfectly secure bit commitment has been proven impossible through asyn…
