Efficient Learning of Structured Quantum Circuits via Pauli Dimensionality and Sparsity

Sabee Grewal, Daniel Liang

We study the problem of efficiently learning an unknown $n$ -qubit unitary channel in diamond distance given query access. We present a general framework showing that if Pauli opera…

Hamiltonian Locality Testing via Trotterized Postselection

John Kallaugher, Daniel Liang

The (tolerant) Hamiltonian locality testing problem, introduced in [Bluhm, Caro,Oufkir `24], is to determine whether a Hamiltonian $H$ is $ε_{1}$ -close to being $k$ -local (…
