QIP 20202020We prove that quantum Gibbs states of spin systems above a certain threshold temperature are approximate quantum Markov networks, meaning that the conditional mutual information decays rapidly with distance. We prove exponential decay (power-law decay) for short-ranged (long-ranged) interacting systems. As consequences, we establish the efficiency of quantum Gibbs sampling algorithms, a strong version of

QIP 20202020The concept of quantum complexity has far-reaching implications spanning theoretical computer science, quantum many-body physics, and high energy physics. The quantum complexity of a unitary transformation or quantum state is defined as the size of the shortest quantum computation that executes the unitary or prepares the state. It is reasonable to expect that the complexity of a quantum state governed

Physical Review Research2020Topological entanglement entropy has been extensively used as an indicator of topologically ordered phases. We study conditions for two-dimensional topologically trivial states to exhibit spurious contributions which suffer topological entanglement entropy. We show that if the state at the boundary of a subregion is a stabilizer state, then it has non-zero spurious contribution on the region if, and only

Interspeech 20202020Speaker identification based on voice input is a fundamental capability in speech processing enabling versatile downstream applications, such as personalization and authentication. With the advent of deep learning, most state-of-the-art methods apply machine learning techniques and derive acoustic embeddings from utterances with convolutional neural networks (CNNs) and recurrent neural networks (RNNs).

Interspeech 20202020Entity Linking (EL) recognizes textual mentions of entities and maps them to the corresponding entities in a Knowledge Graph (KG). In this paper, we propose a novel method for EL on short text using entity representations base on their name labels, descriptions, and other related entities in the KG. We then leverage a pre-trained BERT model to calculate the semantic similarity between the entity and the
