Paper

Emergent quantum state designs and biunitarity in dual-unitary circuit dynamics

Pieter W. Claeys and Austen Lamacraft,

Quantum 6, 738 (2022).

Recent works have investigated the emergence of a new kind of random matrix behaviour in unitary dynamics following a quantum quench. Starting from a time-evolved state, an ensemble of pure…

Paper

One bound to rule them all: from Adiabatic to Zeno

Daniel Burgarth, Paolo Facchi, Giovanni Gramegna, and Kazuya Yuasa,

Quantum 6, 737 (2022).

We derive a universal nonperturbative bound on the distance between unitary evolutions generated by time-dependent Hamiltonians in terms of the difference of their integral actions. We apply…

Paper

Integrability of the $ν=4/3$ fractional quantum Hall edge states

Yichen Hu and Biao Lian,

Quantum 6, 736 (2022).

We investigate the homogeneous chiral edge theory of the filling $\nu=4/3$ fractional quantum Hall state, which is parameterized by a Luttinger liquid velocity matrix and an electron tunneling…

Paper

Genuine multipartite entanglement of quantum states in the multiple-copy scenario

Carlos Palazuelos and Julio I. de Vicente,

Quantum 6, 735 (2022).

Genuine multipartite entanglement (GME) is considered a powerful form of entanglement since it corresponds to those states that are not biseparable, i.e. a mixture of partially separable sta…

Paper

The Classification of Clifford Gates over Qubits

Daniel Grier and Luke Schaeffer,

Quantum 6, 734 (2022).

We examine the following problem: given a collection of Clifford gates, describe the set of unitaries generated by circuits composed of those gates. Specifically, we allow the standard circu…

Paper

Non-ergodic delocalized phase with Poisson level statistics

Weichen Tang and Ivan M. Khaymovich,

Quantum 6, 733 (2022).

Motivated by the many-body localization (MBL) phase in generic interacting disordered quantum systems, we develop a model simulating the same eigenstate structure like in MBL, but in the ran…

Paper

Solvable Criterion for the Contextuality of any Prepare-and-Measure Scenario

Victor Gitton and Mischa P. Woods,

Quantum 6, 732 (2022).

Starting from arbitrary sets of quantum states and measurements, referred to as the prepare-and-measure scenario, an operationally noncontextual ontological model of the quantum statistics a…

Paper

Topological phonons in arrays of ultracold dipolar particles

Marco Di Liberto, Andreas Kruckenhauser, Peter Zoller, and Mikhail A. Baranov,

Quantum 6, 731 (2022).

The notion of topology in physical systems is associated with the existence of a nonlocal ordering that is insensitive to a large class of perturbations. This brings robustness to the behavi…

Paper

A variational quantum algorithm for the Feynman-Kac formula

Hedayat Alghassi, Amol Deshmukh, Noelle Ibrahim, Nicolas Robles, Stefan Woerner, and Christa Zoufal,

Quantum 6, 730 (2022).

We propose an algorithm based on variational quantum imaginary time evolution for solving the Feynman-Kac partial differential equation resulting from a multidimensional system of stochastic…

Paper

Architecture aware compilation of quantum circuits via lazy synthesis

Simon Martiel and Timothée Goubault de Brugière,

Quantum 6, 729 (2022).

Qubit routing is a key problem for quantum circuit compilation. It consists in rewriting a quantum circuit by adding the least possible number of instructions to make the circuit compliant w…

Paper

Solving the Bose-Hubbard model in new ways

Artur Sowa and Jonas Fransson,

Quantum 6, 728 (2022).

We introduce a new method for analysing the Bose-Hubbard model for an array of bosons with nearest neighbor interactions. It is based on a number-theoretic implementation of the creation and…

Paper

Quantum Machine Learning with SQUID

Alessandro Roggero, Jakub Filipek, Shih-Chieh Hsu, and Nathan Wiebe,

Quantum 6, 727 (2022).

In this work we present the Scaled QUantum IDentifier (SQUID), an open-source framework for exploring hybrid Quantum-Classical algorithms for classification problems. The classical infrastru…

Paper

A general quantum algorithm for open quantum dynamics demonstrated with the Fenna-Matthews-Olson complex

Zixuan Hu, Kade Head-Marsden, David A. Mazziotti, Prineha Narang, and Sabre Kais,

Quantum 6, 726 (2022).

Using quantum algorithms to simulate complex physical processes and correlations in quantum matter has been a major direction of quantum computing research, towards the promise of a quantum…

Paper

A device-independent protocol for XOR oblivious transfer

Srijita Kundu, Jamie Sikora, and Ernest Y.-Z. Tan,

Quantum 6, 725 (2022).

Oblivious transfer is a cryptographic primitive where Alice has two bits and Bob wishes to learn some function of them. Ideally, Alice should not learn Bob's desired function choice and Bob…

Paper

One-Shot Hybrid State Redistribution

Eyuri Wakakuwa, Yoshifumi Nakata, and Min-Hsiu Hsieh,

Quantum 6, 724 (2022).

We consider state redistribution of a "hybrid" information source that has both classical and quantum components. The sender transmits classical and quantum information at the same time to t…

Paper

Universal Entanglement Transitions of Free Fermions with Long-range Non-unitary Dynamics

Pengfei Zhang, Chunxiao Liu, Shao-Kai Jian, and Xiao Chen,

Quantum 6, 723 (2022).

Non-unitary evolution can give rise to novel steady states classified by their entanglement properties. In this work, we aim to understand the effect of long-range hopping that decays with…
