Scalable quantum computation, capable of outperforming classical systems for a wide range of tasks, fundamentally relies on quantum error correction (QEC)...
Show MoreUnderstanding the emergence of classicality from the underlying microscopic quantum dynamics—a process that gives rise to the so-called quantum-classical boundary—has long been a central challenge...
Show More
Both discrete quantum systems, such as qubits and qudits, and continuous-variable quantum systems, such as modes of light, play crucial roles as testbeds for the study of quantum information theory and quantum computation...
