Quantum Journal Club: Description of quantum coherence in thermodynamic processes requires constraints beyond free energy
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...

Selection from heaps, row-sorted matrices and X+Y using soft heaps
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...

Observation of conclusive one-way quantum steering and heralded quantum steering
Abstract: Within the hierarchy of quantum correlations, the Einstein-Podolsky-Rosen steering task (also called quantum steering) is distinguished from both entanglement verification and Bell nonlocal...

Architecture and parameter optimization for quantum algorithms
Abstract: In the noisy intermediate-scale quantum era (NISQ), we are likely to achieve practical quantum advantage using near-term programmable quantum hardware. We focus on the variational quantum a...

Entanglement of random hypergraph states
Abstract: 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 n...

Quantum Journal Club: Probing Johnson noise and ballistic transport in normal me
Abstract: Thermally induced electrical currents, known as Johnson noise, cause fluctuating electric and magnetic fields in proximity to a conductor. These fluctuations are intrinsically related to th...
