Munich Quantum Software Forum 2024: Quick Opinions with Jens Eisert and Austin Fowler

Title:
The Quest for Fault Tolerance: Should we give up right away?
Everyone knows or believes large-scale quantum computing applications must be fault- tolerant and will require quantum error correction. And the theory seems to be there. However, turning that into software triggers colossal challenges. Given that fault-tolerant preparation of the initial state (an "empty" circuit) already requires dozens of qubits and hundreds of gates, how we are ever supposed to realize a circuit that actually performs a useful computation? Is there any hope or prospect to get there? And, if yes, what is the starting point to not get overwhelmed?
