Near-optimal incoherent tomography of low-rank quantum channels
Kean Chen, Aadil Oufkir
We study tomography for quantum channels with input dimension , output dimension , and Kraus rank at most , to within diamond norm error , using adaptive…
Quantum channel tomography: optimal bounds and a Heisenberg-to-classical phase transition
Kean Chen, Filippo Girardi, Aadil Oufkir +2
How many black-box queries to a quantum channel are needed to learn its full classical description? This question lies at the heart of quantum channel tomography (also known as qua…
Certifying and learning local quantum Hamiltonians
Andreas Bluhm, Matthias C. Caro, Francisco Escudero Gutiérrez +4
In this work, we study the problems of certifying and learning quantum -local Hamiltonians, for a constant . Our main contributions are as follows: - Certification of Hamilto…
Improved Lower Bounds for Learning Quantum Channels in Diamond Distance
Aadil Oufkir, Filippo Girardi
We prove that learning an unknown quantum channel with input dimension , output dimension , and Choi rank to diamond distance requires $ Ω\!\left( \frac…
