Quantum Journal Club: Extending the lifetime of a quantum bit with error correction in superconducting circuits
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 ...

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...
