Abstract: Quantum computers bring in extraordinary capabilities at solving certain problems by taking classically inaccessible paths. A practical quantum computer will need a large number of qubits w...
Abstract: Topological states of matter provide a fertile ground for discovering new quasiparticles in condensed matter physics, such as Weyl and Dirac fermions, which were originally predicted in hig...
Abstract: Trapped ion systems are a leading platform for quantum simulation of spin models. Current experiments are limited to less than 55 ions due to collisions with background gas that destroy the...
Abstract: Among various implementations of QKD, the entanglement-based approach is especially promising for future applications, as it forms the basis of device-independent quantum secure cryptograph...
Abstract: In science, we often want to characterise dynamical processes to identify the underlying physics and predict the future states of the system. If the state of the system at any time depends ...
Abstract: As quantum computing technology develops, there is a growing interest in finding useful applications of near-term quantum machines. In this talk, I will describe our recent works on using n...
