The abelian state hidden subgroup problem: Learning stabilizer groups and beyond

Marcel Hinsche, Jens Eisert, Jose Carrasco

Identifying the symmetry properties of quantum states is a central theme in quantum information theory and quantum many-body physics. In this work, we investigate quantum learning…

On the average-case complexity of learning output distributions of quantum circuits

Alexander Nietner, Marios Ioannou, Ryan Sweke +4

In this work, we show that learning the output distributions of brickwork random quantum circuits is average-case hard in the statistical query model. This learning model is widely…

Clifford testing: algorithms and lower bounds

Marcel Hinsche, Zongbo Bao, Philippe van Dordrecht +3

We consider the problem of Clifford testing, which asks whether a black-box -qubit unitary is a Clifford unitary or at least -far from every Clifford unitary. We gi…

Efficient distributed inner product estimation via Pauli sampling

Marcel Hinsche, Marios Ioannou, Sofiene Jerbi +3

Cross-platform verification is the task of comparing the output states produced by different physical platforms using solely local quantum operations and classical communication. W…

Will it glue? On short-depth designs beyond the unitary group

Lorenzo Grevink, Jonas Haferkamp, Markus Heinrich +4

We study the formation of short-depth designs beyond the unitary group. We provide a range of results on several groups of broad interest in quantum information science: the Cliffo…

Interactive proofs for verifying (quantum) learning and testing

Matthias C. Caro, Jens Eisert, Marcel Hinsche +3

We consider the problem of testing and learning from data in the presence of resource constraints, such as limited memory or weak data access, which place limitations on the effici…
