Quantum Computers Challenged by Many-Body Chaos by Alexander Altland

Explore the challenges posed by many-body chaos to quantum computers in this 32-minute lecture by Alexander Altland at the International Centre for Theoretical Sciences. Delve into the intersection of condensed matter physics and quantum information as part of the "Condensed Matter Meets Quantum Information" program. Learn about quantum phases of condensed matter, such as superconductors and topological insulators, and their potential as substrates for quantum information processing. Discover the applications of superconducting quantum interference devices (SQUIDs) in encoding qubits and recent proposals for using quantum Hall systems and Majorana modes in quantum wires. Gain insights into topological protection and its role in making quantum systems robust against local disorder and decoherence. This lecture is part of a broader program aimed at bridging the gap between condensed matter and quantum information researchers, featuring courses on quantum information foundations, quantum Hall effects, quantum computation algorithms, superconductivity basics, and non-abelian anyons in fractional quantum Hall states.
