Fault-Tolerant Quantum Computation
Fault-tolerant quantum computing aims to realize practical quantum logic circuits based on noisy hardware. Numerous theoretical and engineering challenges remain to be explored. Engineering issues involve integrating with practical platforms and designing more efficient fault-tolerant schemes, such as how to prepare accurate magic states more efficiently. Theoretical problems include investigating the profound mathematical structures and physical pictures within quantum error-correcting codes. For instance, this involves studying the relationship between code parameters and structures from homological algebra and algebraic geometry, as well as properties like the topological entanglement entropy of the codes.
Notes on this topic are collected in the blog tag for quantum error correction.
Topological Phases of Matter
Many profound physical phenomena originate from the topological properties of a system. The most fascinating aspect of topological states of matter is that certain global topological properties precisely determine the structure of the ground state and its excitations, leading the system to exhibit interesting entanglement and quasiparticle characteristics. From a physical perspective, these properties emerge from complex many-body interactions, representing novel physical behaviour. From the viewpoint of quantum information, they also provide significant inspiration for fault-tolerant quantum computing.
Quantum Simulation
Quantum simulation aims to study physical models on highly controllable atom-laser platforms. The ability to precisely manipulate individual atoms and tune the interactions between them is one of the most remarkable achievements of modern science. These precisely tunable atom-optical systems allow us to simulate various quantum models under exceptionally clean conditions. The optical tweezer-atom array architecture is also one of the most competitive platforms for realizing quantum computing today.
