Abstract: Quantum information science and technology enables informational secure quantum cryptography (quantum communication). This presentation will highlight a few of our progress towards the ulti...
Abstract: Quantum error correction is a key approach to achieve large-scale quantum computing. Due to the low encoding rate of surface codes, fault-tolerant quantum computing schemes based on surface...
Abstract: We report on the experimental violation of multipartite Bell inequalities by entangled states of trapped ions. First, we consider resource states for measurement-based quantum computation o...
Abstract: Quantum error correction (QEC) can overcome the errors experienced by qubits1 and is therefore an essential component of a future quantum computer. To implement QEC, a qubit is redundantly ...
Abstract: Recent studies have developed fundamental limitations on nanoscale thermodynamics, in terms of a set of independent free energy relations. Here we show that free energy relations cannot pro...
Abstract: We use soft heaps to obtain simpler optimal algorithms for selecting the k-th smallest item, and the set of k smallest items, from a heap-ordered tree, from a collection of sorted lists, an...
