A Classical Quadratic Speedup for Planted XOR
Meghal Gupta, William He, Ryan O'Donnell +1
A recent work of Schmidhuber et al (QIP, SODA, & Phys. Rev. X 2025) exhibited a quantum algorithm for the noisy planted XOR problem running quartically faster than all known cla…

Few Single-Qubit Measurements Suffice to Certify Any Quantum State
Meghal Gupta, William He, Ryan O'Donnell
A fundamental task in quantum information science is state certification: testing whether a lab-prepared -qubit state is close to a given hypothesis state. In this work, we show…
