Sample Optimal and Memory Efficient Quantum State Tomography
Yanglin Hu, Enrique Cervero-MartÃn, 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…
Consecutive Measurement Tradeoffs in Quantum Cryptography
Chen-Xun Weng, Minglong Qin, Yanglin Hu +1
Mistrustful quantum cryptographic protocols encode information in incompatible observables, so that any attempt by a dishonest party to access multiple pieces of information necess…
String commitment from unstructured noise
Jiawei Wu, Masahito Hayashi, Marco Tomamichel
Noisy channels are a foundational resource for constructing cryptographic primitives such as string commitment and oblivious transfer. The noisy channel model has been extended to…
Device independent security of quantum key distribution from monogamy-of-entanglement games
Enrique Cervero-MartÃn, 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…
