Quantum Information and Quantum Computation

• Quantum error-correction code: Topological quantum error-correcting codes, homological codes, topological quantum computation.

• Spatiotemporal quantum states: pseudo-density operators, superdensity operators, doubled density operators; quantum chaos; multi-time quantum process..

• Quantum causality, process matrices, quantum Bayesian inference, quantum retrodiction.

• Quantum foundations: quantum discord, quantum entanglement, quantum steering, Bell nonlocality, quantum contextuality.
