Paper

Automated Generation of Shuttling Sequences for a Linear Segmented Ion Trap Quantum Computer

Jonathan Durandau, Janis Wagner, Frédéric Mailhot, Charles-Antoine Brunet, Ferdinand Schmidt-Kaler, Ulrich Poschinger, and Yves Bérubé-Lauzière,

Quantum 7, 1175 (2023).

A promising approach for scaling-up trapped-ion quantum computer platforms is by storing multiple trapped-ion qubit sets ('ion crystals') in segmented microchip traps and to interconnect the…

Paper

Quantum Alphatron: quantum advantage for learning with kernels and noise

Siyi Yang, Naixu Guo, Miklos Santha, and Patrick Rebentrost,

Quantum 7, 1174 (2023).

At the interface of machine learning and quantum computing, an important question is what distributions can be learned provably with optimal sample complexities and with quantum-accelerated…

Paper

A rapidly mixing Markov chain from any gapped quantum many-body system

Sergey Bravyi, Giuseppe Carleo, David Gosset, and Yinchen Liu,

Quantum 7, 1173 (2023).

We consider the computational task of sampling a bit string $x$ from a distribution $\pi(x)=|\langle x|\psi\rangle|^2$, where $\psi$ is the unique ground state of a local Hamiltonian $H$. Our main r…

Paper

Relaxing Hardware Requirements for Surface Code Circuits using Time-dynamics

Matt McEwen, Dave Bacon, and Craig Gidney,

Quantum 7, 1172 (2023).

The typical time-independent view of quantum error correction (QEC) codes hides significant freedom in the decomposition into circuits that are executable on hardware. Using the concept of d…

Paper

Preparing quantum many-body scar states on quantum computers

Erik J. Gustafson, Andy C. Y. Li, Abid Khan, Joonho Kim, Doga Murat Kurkcuoglu, M. Sohaib Alam, Peter P. Orth, Armin Rahmani, and Thomas Iadecola,

Quantum 7, 1171 (2023).

Quantum many-body scar states are highly excited eigenstates of many-body systems that exhibit atypical entanglement and correlation properties relative to typical eigenstates at the same en…

Paper

Dissipative phase transitions in $n$-photon driven quantum nonlinear resonators

Fabrizio Minganti, Vincenzo Savona, and Alberto Biella,

Quantum 7, 1170 (2023).

We investigate and characterize the emergence of finite-component dissipative phase transitions (DPTs) in nonlinear photon resonators subject to $n$-photon driving and dissipation. Exploiting…

Paper

The quantum switch is uniquely defined by its action on unitary operations

Qingxiuxiong Dong, Marco Túlio Quintino, Akihito Soeda, and Mio Murao,

Quantum 7, 1169 (2023).

The quantum switch is a quantum process that creates a coherent control between different unitary operations, which is often described as a quantum process which transforms a pair of unitary…

Paper

Minimum Trotterization Formulas for a Time-Dependent Hamiltonian

Tatsuhiko N. Ikeda, Asir Abrar, Isaac L. Chuang, and Sho Sugiura,

Quantum 7, 1168 (2023).

When a time propagator $e^{\delta t A}$ for duration $\delta t$ consists of two noncommuting parts $A=X+Y$, Trotterization approximately decomposes the propagator into a product of exponentials of…

Paper

Quantum algorithm for ground state energy estimation using circuit depth with exponentially improved dependence on precision

Guoming Wang, Daniel Stilck França, Ruizhe Zhang, Shuchen Zhu, and Peter D. Johnson,

Quantum 7, 1167 (2023).

A milestone in the field of quantum computing will be solving problems in quantum chemistry and materials faster than state-of-the-art classical methods. The current understanding is that ac…

Paper

Covariant catalysis requires correlations and good quantum reference frames degrade little

Lauritz van Luijk, Reinhard F. Werner, and Henrik Wilming,

Quantum 7, 1166 (2023).

Catalysts are quantum systems that open up dynamical pathways between quantum states which are otherwise inaccessible under a given set of operational restrictions while, at the same time, t…

Paper

On low-depth algorithms for quantum phase estimation

Hongkang Ni, Haoya Li, and Lexing Ying,

Quantum 7, 1165 (2023).

Quantum phase estimation is one of the critical building blocks of quantum computing. For early fault-tolerant quantum devices, it is desirable for a quantum phase estimation algorithm to (1…

Paper

Fault-tolerant quantum computation of molecular observables

Mark Steudtner, Sam Morley-Short, William Pol, Sukin Sim, Cristian L. Cortes, Matthias Loipersberger, Robert M. Parrish, Matthias Degroote, Nikolaj Moll, Raffaele Santagati, and Michael Streif,

Quantum 7, 1164 (2023).

Over the past three decades significant reductions have been made to the cost of estimating ground-state energies of molecular Hamiltonians with quantum computers. However, comparatively lit…

Paper

Robust Extraction of Thermal Observables from State Sampling and Real-Time Dynamics on Quantum Computers

Khaldoon Ghanem, Alexander Schuckert, and Henrik Dreyer,

Quantum 7, 1163 (2023).

Simulating properties of quantum materials is one of the most promising applications of quantum computation, both near- and long-term. While real-time dynamics can be straightforwardly imple…

Paper

Operational meanings of a generalized conditional expectation in quantum metrology

Mankei Tsang,

Quantum 7, 1162 (2023).

A unifying formalism of generalized conditional expectations (GCEs) for quantum mechanics has recently emerged, but its physical implications regarding the retrodiction of a quantum observab…

Paper

Finite-time Landauer principle beyond weak coupling

Alberto Rolandi and Martí Perarnau-Llobet,

Quantum 7, 1161 (2023).

Landauer's principle gives a fundamental limit to the thermodynamic cost of erasing information. Its saturation requires a reversible isothermal process, and hence infinite time. We develop…

Paper

Integrable Quantum Circuits from the Star-Triangle Relation

Yuan Miao and Eric Vernier,

Quantum 7, 1160 (2023).

The star-triangle relation plays an important role in the realm of exactly solvable models, offering exact results for classical two-dimensional statistical mechanical models. In this articl…
