Quantum policy gradient algorithms
Sofiene Jerbi, Arjan Cornelissen, Māris Ozols +1
Understanding the power and limitations of quantum access to data in machine learning tasks is primordial to assess the potential of quantum computing in artificial intelligence. P…
Upper Bounds on the Distillable Randomness of Bipartite Quantum States
Ludovico Lami, Bartosz Regula, Xin Wang +1
The distillable randomness of a bipartite quantum state is an information-theoretic quantity equal to the largest net rate at which shared randomness can be distilled from the stat…
Single-qubit loss-tolerant quantum position verification protocol secure against entangled attackers
Llorenç Escolà-Farràs, Florian Speelman
Protocols for quantum position verification (QPV) which combine classical and quantum information are insecure in the presence of loss. We study the exact loss-tolerance of the mos…
(No) Quantum space-time tradeoff for USTCON
Simon Apers, Stacey Jeffery, Galina Pass +1
Undirected -connectivity is important both for its applications in network problems, and for its theoretical connections with logspace complexity. Classically, a long line of w…
Generating EPR-pairs from an -party resource state
Sergey Bravyi, Yash Sharma, Mario Szegedy +1
Motivated by quantum network applications over classical channels, we initiate the study of -party resource states from which LOCC protocols can create EPR-pairs between any …
Parallel repetition of local simultaneous state discrimination
Llorenç Escolà-Farràs, Jaròn Has, Maris Ozols +2
Local simultaneous state discrimination (LSSD) is a recently introduced problem in quantum information processing. Its classical version is a non-local game played by non-communica…
