On the set of reduced states of translation invariant, infinite quantum systems
Vjosa Blakaj, Michael M. Wolf
The set of two-body reduced states of translation invariant, infinite quantum spin chains can be approximated from inside and outside using matrix product states and marginals of f…
Hay from the haystack: explicit examples of exponential quantum circuit complexity
Yifan Jia, Michael M. Wolf
The vast majority of quantum states and unitaries have circuit complexity exponential in the number of qubits. In a similar vein, most of them also have exponential minimum descrip…
'Interaction-Free' Channel Discrimination
Markus Hasenöhrl, Michael M. Wolf
In this work, we investigate the question, which objects one can discriminate perfectly by 'interaction-free' measurements. To this end, we interpret the Elitzur-Vaidman bomb-teste…
Measurement-Disturbance Tradeoff Outperforming Optimal Cloning
Lukas Knips, Jan Dziewior, Anna-Lena K. Hashagen +3
One of the characteristic features of quantum mechanics is that every measurement that extracts information about a general quantum system necessarily causes an unavoidable disturb…
When Do Composed Maps Become Entanglement Breaking?
Matthias Christandl, Alexander Müller-Hermes, Michael M. Wolf
For many completely positive maps repeated compositions will eventually become entanglement breaking. To quantify this behaviour we develop a technique based on the Schmidt number:…
Universality and Optimality in the Information-Disturbance Tradeoff
Anna-Lena K. Hashagen, Michael M. Wolf
We investigate the tradeoff between the quality of an approximate version of a given measurement and the disturbance it induces in the measured quantum system. We prove that if the…
