Paper

Anonymous conference key agreement in linear quantum networks

Jarn de Jong, Frederik Hahn, Jens Eisert, Nathan Walk, and Anna Pappa,

Quantum 7, 1117 (2023).

Sharing multi-partite quantum entanglement between parties allows for diverse secure communication tasks to be performed. Among them, conference key agreement (CKA) – an extension of key dis…

Paper

Coherent errors and readout errors in the surface code

Áron Márton and János K. Asbóth,

Quantum 7, 1116 (2023).

We consider the combined effect of readout errors and coherent errors, i.e., deterministic phase rotations, on the surface code. We use a recently developed numerical approach, via a mapping…

Paper

Random unitaries, Robustness, and Complexity of Entanglement

J. Odavić, G. Torre, N. Mijić, D. Davidović, F. Franchini, and S. M. Giampaolo,

Quantum 7, 1115 (2023).

It is widely accepted that the dynamic of entanglement in presence of a generic circuit can be predicted by the knowledge of the statistical properties of the entanglement spectrum. We teste…

Paper

Tilted Hardy paradoxes for device-independent randomness extraction

Shuai Zhao, Ravishankar Ramanathan, Yuan Liu, and Paweł Horodecki,

Quantum 7, 1114 (2023).

The device-independent paradigm has had spectacular successes in randomness generation, key distribution and self-testing, however most of these results have been obtained under the assumpti…

Paper

Quantum Gauge Networks: A New Kind of Tensor Network

Kevin Slagle,

Quantum 7, 1113 (2023).

Although tensor networks are powerful tools for simulating low-dimensional quantum physics, tensor network algorithms are very computationally costly in higher spatial dimensions. We introdu…

Paper

A “thoughtful” Local Friendliness no-go theorem: a prospective experiment with new assumptions to suit

Howard M. Wiseman, Eric G. Cavalcanti, and Eleanor G. Rieffel,

Quantum 7, 1112 (2023).

A recent paper by two of us and co-workers [1], based on an extended Wigner's friend scenario, demonstrated that certain empirical correlations predicted by quantum theory (QT) violate inequ…

Paper

Encoding trade-offs and design toolkits in quantum algorithms for discrete optimization: coloring, routing, scheduling, and other problems

Nicolas PD Sawaya, Albert T Schmitz, and Stuart Hadfield,

Quantum 7, 1111 (2023).

Challenging combinatorial optimization problems are ubiquitous in science and engineering. Several quantum methods for optimization have recently been developed, in different settings includ…

Paper

Quantum Interior Point Methods for Semidefinite Optimization

Brandon Augustino, Giacomo Nannicini, Tamás Terlaky, and Luis F. Zuluaga,

Quantum 7, 1110 (2023).

We present two quantum interior point methods for semidefinite optimization problems, building on recent advances in quantum linear system algorithms. The first scheme, more similar to a cla…

Paper

Noise-robust ground state energy estimates from deep quantum circuits

Harish J. Vallury, Michael A. Jones, Gregory A. L. White, Floyd M. Creevey, Charles D. Hill, and Lloyd C. L. Hollenberg,

Quantum 7, 1109 (2023).

In the lead up to fault tolerance, the utility of quantum computing will be determined by how adequately the effects of noise can be circumvented in quantum algorithms. Hybrid quantum-classi…

Paper

LIMDD: A Decision Diagram for Simulation of Quantum Computing Including Stabilizer States

Lieuwe Vinkhuijzen, Tim Coopmans, David Elkouss, Vedran Dunjko, and Alfons Laarman,

Quantum 7, 1108 (2023).

Efficient methods for the representation and simulation of quantum states and quantum operations are crucial for the optimization of quantum circuits. Decision diagrams (DDs), a well-studied…

Paper

Forging quantum data: classically defeating an IQP-based quantum test

Gregory D. Kahanamoku-Meyer,

Quantum 7, 1107 (2023).

Recently, quantum computing experiments have for the first time exceeded the capability of classical computers to perform certain computations – a milestone termed "quantum computational adv…

Paper

Operational Quantum Average-Case Distances

Filip B. Maciejewski, Zbigniew Puchała, and Michał Oszmaniec,

Quantum 7, 1106 (2023).

We introduce distance measures between quantum states, measurements, and channels based on their statistical distinguishability in generic experiments. Specifically, we analyze the average T…

Paper

Testing identity of collections of quantum states: sample complexity analysis

Marco Fanizza, Raffaele Salvia, and Vittorio Giovannetti,

Quantum 7, 1105 (2023).

We study the problem of testing identity of a collection of unknown quantum states given sample access to this collection, each state appearing with some known probability. We show that for…

Paper

The Round Complexity of Local Operations and Classical Communication (LOCC) in Random-Party Entanglement Distillation

Guangkuo Liu, Ian George, and Eric Chitambar,

Quantum 7, 1104 (2023).

A powerful operational paradigm for distributed quantum information processing involves manipulating pre-shared entanglement by local operations and classical communication (LOCC). The LOCC…

Paper

On a gap in the proof of the generalised quantum Stein’s lemma and its consequences for the reversibility of quantum resources

Mario Berta, Fernando G. S. L. Brandão, Gilad Gour, Ludovico Lami, Martin B. Plenio, Bartosz Regula, and Marco Tomamichel,

Quantum 7, 1103 (2023).

We show that the proof of the generalised quantum Stein's lemma [Brandão & Plenio, Commun. Math. Phys. 295, 791 (2010)] is not correct due to a gap in the argument leading to Lemma III.9. He…

Paper

Integral formula for quantum relative entropy implies data processing inequality

Péter E. Frenkel,

Quantum 7, 1102 (2023).

Integral representations of quantum relative entropy, and of the directional second and higher order derivatives of von Neumann entropy, are established, and used to give simple proofs of fu…
