Acknowledgments s
II am indebted to Harry Buhrman for his guidance, advice, and comradeship. Mostt problems addressed in this thesis were raised by him; his ideas also contributedd to many of the solutions. I am also very grateful to Paul Vitanyi, whoo offered me the PhD position and whose pragmatic yet highly competent managementt style I admire.
Speciall thanks go to Ronald de Wolf. He was the first real quantum-computingg researcher I ever talked to, the night before AQIP 98. His close readingg of the thesis improved it a lot; all remaining errors are of course mine. He,, John Tromp, and I shared an office—the drie 'heren' frequently were the onlyy people at the institute at night and during the weekend.
II also thank my other coauthors of the papers that are the foundation of thiss thesis: Andris Ambainis, Yevgeniy Dodis, Lance Fortnow, Peter H0yer, Sergee Massar, and Ilan Newman. During my studies, I spent a substantial amountt of time as guest of Lov Grover at Bell Labs. What I know about quantumm search, I learned from him.
Twoo long-time mentors deserve special mention here: Prof. Dr. Karl Hensen,, my "Vertrauensdozent" in the Studienstiftung, was a constant point off reference outside my specialty. FVom Prof. Dr. Dr. h.c. mult. Günter Hotz II learned to critically review objectives of research in a wider context.
Forr many pleasant, instructive, and fruitful scientific discussions, I thank Scottt Aaronson, Luis Antunes, Eldar Fischer, Peter Gacs, Mart de Graaf, Pe-terr Grünwald, Jaap-Henk Hoepman, Troy Lee, Ashwin Nayak, Daniel Preda, Yaoyunn Shi, Robert Spalek, and Arjen de Vries. For introducing me to new worlds,, for advice and friendship, and generally a good time I thank Tor ben Hagerup,, Ute Röhrig, Richard Hahnloser, Sebastian Seung, Tarmo Johannes, Dashaa Beltsiukova, Liddy Shriver, Markus Jakobsson, and Susanne Wetzel. Thankss to Rudi Cilibrasi and Rudolf Janz for proofreading drafts of this the-siss and instructing me to exorcize parentheses; Stefan Manegold and Kolja Sulimmaa provided valuable advice about printing this thesis.
II am grateful to my parents for their support throughout my studies. Andd Tzveta, thanks for always stimulating me to finish this thesis and for providingg distraction from work!
