November 18 10:15 in 1520732  Efficient Characterization and Optimal Control of Open Quantum Systems Daniel Reich, University of Kassel, Germany Since no system can ever be completely isolated from its environment the study of open quantum systems is pivotal to reliably and accurately control complex quantum systems. In practice, reliability of the control needs to be confirmed via certification of the target evolution while accuracy requires the derivation of highfidelity control schemes in the presence of decoherence. We present frameworks for highly efficient characterization of unitary transformations and their application to gate certification and Optimal Control Theory. Furthermore, we devise control techniques that work not only against but also with the environment to fulfill certain quantum control tasks. In particular, we will demonstrate the power of Optimal Control Theory in the presence of environmental effects for vibrational cooling of molecules and superconducting quantum gate implementations. 
October 13 14:15 in 1520616  Qubit interference at avoided crossings: The role of driving shape and bath coupling Ralf Blattmann, University of Augsburg, Germany Sweeping through an avoided crossing with a periodic, large amplitude driving leads to a sequence of transition, where the phase accumulation between transition may result in constructive or destructive interference. This leads to so called LandauZenerStueckelbergMajorana (LZSM) interference patterns. We derive the structure of the LZSM patterns for a qubit that experiences quantum dissipation and is additionally subjected to timeperiodic but otherwise general driving. Numerical as well as analytical results predict a peak structure that depends sensitively on the details of the qubitbath coupling. The Fourier transforms of the LZSM patterns exhibit arc structures which reflect the shape of the driving, and provide an opportunity to characterize the qubit coherence. We derive an analytical description for the observed structures and numerically determine their decay as a function of dissipation strength and temperature.

June 12 15:15 in 1525323  Quantum digital signatures Erika Andersson, HeriotWatt University, Edinburgh, Scotland Digital signatures ensure that messages cannot be forged or tampered with. They are widely used to provide security for electronic communications, for example in financial transactions and electronic mail. Importantly, signed messages are also transferrable, meaning that if one recipient accepts a message as genuine, then she is guaranteed that others will also accept the same message if it is forwarded. Digital signatures are different from encryption, which guarantees the privacy of a message. Currently used classical digital signature schemes, however, only offer security relying on unproven computational assumptions. In contrast, quantum digital signatures (QDS), similar to quantum key distribution (QKD), offer informationtheoretic security based on principles of quantum mechanics. A serious drawback of previous QDS schemes is however that they require longterm quantum memory, making them unfeasible. We present protocols which do not need quantum memory and which use only standard linear optical components and photodetectors. With this, it seems that QDS and QKD are similar in terms of experimental requirements. Important work remains in investigating which QDS schemes are most suited for real applications, and in completing full security proofs.
