Paper

Pure non-Markovian evolutions

Dario De Santis,

Quantum 7, 1124 (2023).

Non-Markovian dynamics are characterized by information backflows, where the evolving open quantum system retrieves part of the information previously lost in the environment. Hence, the ver…

Paper

Correcting non-independent and non-identically distributed errors with surface codes

Konstantin Tiurev, Peter-Jan H. S. Derks, Joschka Roffe, Jens Eisert, and Jan-Michael Reiner,

Quantum 7, 1123 (2023).

A common approach to studying the performance of quantum error correcting codes is to assume independent and identically distributed single-qubit errors. However, the available experimental…

Paper

Quantum error correction with fractal topological codes

Arpit Dua, Tomas Jochym-O’Connor, and Guanyu Zhu,

Quantum 7, 1122 (2023).

Recently, a class of fractal surface codes (FSCs), has been constructed on fractal lattices with Hausdorff dimension $2+\epsilon$, which admits a fault-tolerant non-Clifford CCZ gate [1]. We i…

Paper

Warm-Started QAOA with Custom Mixers Provably Converges and Computationally Beats Goemans-Williamson’s Max-Cut at Low Circuit Depths

Reuben Tate, Jai Moondra, Bryan Gard, Greg Mohler, and Swati Gupta,

Quantum 7, 1121 (2023).

We generalize the Quantum Approximate Optimization Algorithm (QAOA) of Farhi et al. (2014) to allow for arbitrary separable initial states with corresponding mixers such that the starting st…

Paper

Testing symmetry on quantum computers

Margarite L. LaBorde, Soorya Rethinasamy, and Mark M. Wilde,

Quantum 7, 1120 (2023).

Symmetry is a unifying concept in physics. In quantum information and beyond, it is known that quantum states possessing symmetry are not useful for certain information-processing tasks. For…

Paper

Why interference phenomena do not capture the essence of quantum theory

Lorenzo Catani, Matthew Leifer, David Schmid, and Robert W. Spekkens,

Quantum 7, 1119 (2023).

Quantum interference phenomena are widely viewed as posing a challenge to the classical worldview. Feynman even went so far as to proclaim that they are the $\textit{only mystery}$ and the…

Paper

Analysis of arbitrary superconducting quantum circuits accompanied by a Python package: SQcircuit

Taha Rajabzadeh, Zhaoyou Wang, Nathan Lee, Takuma Makihara, Yudan Guo, and Amir H. Safavi-Naeini,

Quantum 7, 1118 (2023).

Superconducting quantum circuits are a promising hardware platform for realizing a fault-tolerant quantum computer. Accelerating progress in this field of research demands general approaches…

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…
