Ghent University
26th Conference on Quantum Information Processing
A message from TQC:
The TQC Steering Committee is seeking a local organizer for the year 2024 and invites individuals who are interested in hosting the event to submit an expression of interest (EOI) to Min-Hsiu Hsieh via email at minhsiuh@gmail.com or to any of the Steering Committee members.
The program for QIP2023 can be downloaded here.
The international conference on Quantum Information Processing (QIP) is the premier annual meeting for quantum information research. Since the first meeting in Aarhus (Denmark) in 1998, the conference has featured breakthroughs by leaders in the disciplines of computing, cryptography, information theory, mathematics, and physics.
The scientific objective of the series is to gather the theoretical quantum information community to present and discuss the latest groundbreaking work in the field.
QIP 2023 will be hosted by the Quantum Group of Ghent University.
