Sample-optimal learning of stabilizer states

Rebecca Chang, Matthias C. Caro, Martin Larocca +1

It is well-known that learning a pure $n$ -qubit stabilizer state $∣ ψ ⟩$ both requires, and can be accomplished with, access to a number of copies of $∣ ψ ⟩$ linear in $n$ .…

Classical shadows over symmetric spaces

Rebecca Chang, Maureen Krumtünger, Martin Larocca +1

Efficiently learning expectation values of unknown quantum states via classical shadows has become an important primitive in both theoretical and experimental aspects of quantum co…
