Entanglement of random hypergraph states
内容： Random quantum states and operations are of fundamental and practical interests. In this work, we investigate the entanglement properties of random hypergraph states, which generalize the notio...

On the existence of thermodynamic potentials for quantum systems: A resource-theoretic approach
内容： In equilibrium thermodynamics, the Boltzmann entropy serves as a complete thermodynamic potential that characterizes state convertibility in a necessary and sufficient manner. In this talk, I w...

Progress toward an information theoretic account of why apples fall
内容： Here are three things about gravity--one problem, one fact, and a piece of lore: (1) Gravity is the only known force, which is not understood on the quantum level. (2) Gravity is "holographic":...

Machine Learning Methods in Quantum Physics
内容： In quantum physics, we usually face exponentially large degrees of freedom and the large-scale data obtained from quantum systems, which constantly defy our analysis capability. Here, we sketch...

High coherence fluxonium and its two-qubit gate scheme
内容： Improving control over physical qubits is a crucial component of quantum computing research. We report our recent fluxonium qubit with coherence time reaching T2*= 1.48±0.13 ms [1], which excee...
