Alexander Poremba

I am a third year Ph.D. student in computer science at Caltech under the supervision of Thomas Vidick. I am affiliated with the Department of Computing and Mathematical Sciences and the Institute for Quantum Information and Matter. My research is supported by the Kortschak Scholars Fellowship and the ERP Fellowship by the German National Academic Foundation.

My research is focused on quantum computation and cryptography. I'm mainly interested in designing new applications for quantum computers, including near-term quantum algorithms and novel cryptographic protocols. Much of my work focuses on the developement of quantum computing applications that lie beyond the scope of conventional digital computers. More recently, I've been working on quantum copy-protection and various cryptographic protocols based on lattice-based cryptography.

Curriculum Vitae

PhD, Computer Science, California Institute of Technology (2018 - present)
MSc, Physics, University of Heidelberg (2015 - 2017)
BSc, Mathematics, University of Heidelberg (2011 - 2015)

I was a long-term visitor at the Simons Institute for the Theory of Computing at the University of California, Berkeley, to attend the 2020 spring program The Quantum Wave in Computing. In the summer of 2018, I was awarded a Quantum Computing Summer Fellowship to visit Los Alamos National Laboratory, New Mexico. Before I came to Caltech, I was a long-term visitor at the University of Copenhagen, where I was fortunate to work with Gorjan Alagic at the Centre for the Mathematics of Quantum Theory.

A detailed academic CV is available upon request.
