A promising near-term application of a quantum computer consisting of O(100) qubits is quantum simulation of fermionic systems, which exceeds the computational power of the world’s largest classical supercomputer due to the exponential growth of the Hilbert-space size. The target systems range from large molecules in quantum chemistry such as fertilizer made with lower energy cost, to strongly correlated electronic materials such as the notoriously difficult high-Tc superconductors. This killer app happens to coincide with Feynman’s original vision of universal quantum simulator, which uses a quantum system to simulate another and hence “fight fire with fire”.

Entanglement spectrum, the full spectrum of the reduced density matrix of a subsystem, plays a major role in characterising many-body quantum systems. In recent years, it has been widely studied in the fields of condensed matter physics, quantum information, high energy and black-hole physics.

A hallmark feature of topological physics is the presence of one-way propagating chiral modes at the system boundary. The chirality of these edge modes is a consequence of the topological character of the bulk.
