Quantum Computing in the Presence of Errors

Explore the challenges and potential of quantum computing in this colloquium talk by Ignacio Cirac, Director of the Max Planck Institute of Quantum Optics. Delve into the promise of quantum computers to solve problems beyond the capabilities of classical supercomputers, from basic mathematical operations to simulating quantum materials and chemical compounds. Examine recent advances that have led to the first quantum computer prototypes, their current limitations, and the hope for practical applications. Investigate how errors may impact quantum computers in optimization problems and revisit the challenge of solving quantum many-body problems with imperfect systems. Gain insights into the prospects of achieving quantum advantage despite the presence of errors in current quantum computing technologies.
