Single-Qubit Measurements Recovered Sparse Entangled States
The method avoided entangling measurement gates under sparsity assumptions.
Summary
The method avoided entangling measurement gates under sparsity assumptions.
The authors show that quantum states sparse in an unknown product basis can be learned from single-qubit measurements with polynomial sample complexity. Constant sparsity also permits polynomial classical computation; polynomially growing sparsity can make the classical step harder. The guarantees rely on the stated sparsity and basis structure.
Why it matters
The method avoided entangling measurement gates under sparsity assumptions.
