Anti-symmetrization is cheap and useful
Adam Bene Watts, John Bostanci, Matthias C. Caro +3
We consider the computational task of anti-symmetrization of an unknown mixed quantum state: Given iid copies of a rank- qudit state $ρ=\sum_{i=1}^r λ_i |φ_i\rangle\!\langleφ_i|…
Cloning is as Hard as Learning for Stabilizer States
Nikhil Bansal, Matthias C. Caro, Gaurav Mahajan
The impossibility of simultaneously cloning non-orthogonal states lies at the foundations of quantum theory. Even when allowing for approximation errors, cloning an arbitrary unkno…
Improved classical shadows from local symmetries in the Schur basis
Daniel Grier, Sihan Liu, Gaurav Mahajan
We study the sample complexity of the classical shadows task: what is the fewest number of copies of an unknown state you need to measure to predict expected values with respect to…
