SupercheQ: Quantum Advantage for Distributed Databases

E. R. Anschuetz, P. Gokhale, B. Tonekaboni +18

We introduce Supercheq, a family of quantum protocols that achieves asymptotic advantage over classical protocols for checking the equivalence of files, a task also known as finger…

Fragmentation is Efficiently Learnable by Quantum Neural Networks

Mikhail Mints, Eric R. Anschuetz

In certain classes of physical quantum systems, the exponentially large state space "fragments" into many low-dimensional, dynamically disconnected subspaces. We introduce a learni…

Optimizing Sparse SYK

Matthew Ding, Robbie King, Bobak T. Kiani +1

Finding the ground state of strongly-interacting fermionic systems is often the prerequisite for fully understanding both quantum chemistry and condensed matter systems. The Sachde…

Arbitrary Polynomial Separations in Trainable Quantum Machine Learning

Eric R. Anschuetz, Xun Gao

Recent theoretical results in quantum machine learning have demonstrated a general trade-off between the expressive power of quantum neural networks (QNNs) and their trainability;…

Q-CHOP: Quantum constrained Hamiltonian optimization

Michael A. Perlin, Ruslan Shaydulin, Benjamin P. Hall +7

Combinatorial optimization problems that arise in science and industry typically have constraints. Yet the presence of constraints makes them challenging to tackle using both class…

Quantum Glassiness From Efficient Learning

Eric R. Anschuetz

We show a relation between quantum learning theory and algorithmic hardness. We use the existence of efficient, local learning algorithms for energy estimation -- such as the class…
