Quantum Channel Certification with Incoherent Strategies
Omar Fawzi, Nicolas Flammarion, Aurélien Garivier +1
In the problem of quantum channel certification, we have black box access to a quantum process and would like to decide if this process matches some predefined specification or is…

Sample-Optimal Quantum Process Tomography with Non-Adaptive Incoherent Measurements
Aadil Oufkir
How many copies of a quantum process are necessary and sufficient to construct an approximate classical description of it? We extend the result of Surawy-Stepney, Kahn, Kueng, and…

Lower Bounds on Learning Pauli Channels with Individual Measurements
Omar Fawzi, Aadil Oufkir, Daniel Stilck França
Understanding the noise affecting a quantum device is of fundamental importance for scaling quantum technologies. A particularly important class of noise models is that of Pauli ch…
