Fault Tolerance for Quantum Inputs and Outputs with Matthias Christandl

What happens to fault tolerance when a quantum computer's job is not to spit out a classical answer, but to produce a quantum state that gets sent somewhere else — to another core, another machine, or across a network? Mathias Christandl, professor at the University of Copenhagen and director of the Quantum for Life Center, walks Sebastian through a reframing of the fault tolerance theorem for quantum input and quantum output, and what that shift means for distributed quantum computing, channel capacities, and the practical path to useful quantum simulation in the life sciences.
