Quantitative Quantum Zeno and Strong Damping Limits in Strong Topology
Robert Salzmann
Frequent applications of a mixing quantum operation to a quantum system slow down its time evolution and eventually drive it into the invariant subspace of the named operation. We…
Optimal Fidelity Estimation from Binary Measurements for Discrete and Continuous Variable Systems
Omar Fawzi, Aadil Oufkir, Robert Salzmann
Estimating the fidelity between a desired target quantum state and an actual prepared state is essential for assessing the success of experiments. For pure target states, we use fu…
Convergence Rates for the Trotter Splitting for Unbounded Operators
Simon Becker, Niklas Galke, Robert Salzmann +1
We study convergence rates of the Trotter splitting in the strong operator topology. In the first part, we use complex interpola…
Robustness of Fixed Points of Quantum Channels and Application to Approximate Quantum Markov Chains
Robert Salzmann, Bjarne Bergh, Nilanjana Datta
Given a quantum channel and a state which satisfy a fixed point equation approximately (say, up to an error ), can one find a new channel and a state, which are respec…
An invitation to the sample complexity of quantum hypothesis testing
Hao-Chung Cheng, Nilanjana Datta, Nana Liu +3
Quantum hypothesis testing (QHT) has been traditionally studied from the information-theoretic perspective, wherein one is interested in the optimal decay rate of error probabiliti…
