Personal Information
Christopher Portmann, PhD student
Department of Mathematical and Computing Sciences

Research Interests
Anything related to quantum information theory, such as quantum coding, channel capacities, entropy measures, and applications to quantum cryptography.
I am currently working on encryption schemes which use quantum states as keys, and on classical privacy amplification against a quantum adversary.
