Simon's Algorithm for the Even-Mansour Cipher on Quantum Hardware
Anina Köhler, Jakob Murauer, Tim Heine +2
Simon's algorithm is a polynomial period-finding algorithm that has been used to exploit the algebraic structure of specific symmetric ciphers, showing that exponential speedups in…

Monitoring of quantum walks with weak measurements
Klaus Ziegler, Tim Heine, Sabine Tornow
Measurements can be used to monitor the evolution of quantum systems and can give rise to quantized return statistics. It is known that the mean return time is quantized for strong…

Quantum Walks: First Hitting Times with Weak Measurements
Tim Heine, Eli Barkai, Klaus Ziegler +1
We study the first detected recurrence time problem of continuous-time quantum walks on graphs. While previous works have employed projective measurements to determine the first re…
