Characterization of the 3dδ Rydberg state of MgAr+ using a quantum-control optical scheme

M. Génévriez, D. Wehrli, T. Berglitsch, and F. Merkt

Phys. Rev. A 104, 042811 (2021) - Published 18 October, 2021

The authors developed a highly sensitive method based on a quantum-control double-resonance-spectroscopy scheme to study electronically excited states of molecular ions that do not dissociate. The method is used to study the 3dδ Rydberg state of MgAr+, and the results contribute to the first extensive characterization of the Rydberg states of a molecular cation.

Algebraic-geometric characterization of tripartite entanglement

Masoud Gharahi and Stefano Mancini

Phys. Rev. A 104, 042402 (2021) - Published 4 October, 2021

On the basis of an algebraic-geometric approach, the authors provide a rigorous characterization of pure states of three-qudit systems in terms of a finite number of families and subfamilies. The characterization has operational relevance for quantifying entanglement as a resource.

Fault-tolerant quantum error correction using error weight parities

Theerapat Tansuwannont and Debbie Leung

Phys. Rev. A 104, 042410 (2021) - Published 7 October, 2021

Current fault-tolerant quantum computation protocols require the preparation of a large number of auxiliary qubits. In contrast, the “weight parity error correction” introduced here is a remarkably qubit-efficient technique for correcting even high-weight errors in some stabilizer codes, provided that the weight parity is known.

Toward witnessing molecular exciton entanglement from spectroscopy

Andrew E. Sifain, Francesca Fassioli, and Gregory D. Scholes

Phys. Rev. A 104, 042416 (2021) - Published 20 October, 2021

Entanglement is both fragile and challenging to quantify experimentally, since the state density matrix is not readily available. Here, the authors propose an experimental measure of multipartite entanglement of excitons in some chemical systems using nonlinear optical spectroscopy.

Parametrized Hamiltonian simulation using quantum optimal control

Paul Kairys and Travis S. Humble

Phys. Rev. A 104, 042602 (2021) - Published 8 October, 2021

Building on known quantum control methods, the authors propose a technique to scalably use optimal control to simulate quantum dynamics. They validate this approach with numerical simulation of a system of superconducting transmons.

Theory of dissociative recombination of molecular ions with competing direct and indirect mechanisms applied to CH+

Xianwu Jiang, Josh Forer, Chi Hong Yuen, Mehdi Ayouz, and Viatcheslav Kokoouline

Phys. Rev. A 104, 042801 (2021) - Published 4 October, 2021

The authors present a computational analysis of dissociative recombination of CH+, in which both direct and indirect mechanisms are included. Good agreement with experiments is found in a wide regime while an explanation for disagreement was provided at lower energies. The theoretical method used in this study could be applicable in a wide range of diatomic cations.

Optimized pulsed sideband cooling and enhanced thermometry of trapped ions

A. J. Rasmusson, Marissa D'Onofrio, Yuanheng Xie, Jiafeng Cui, and Philip Richerme

Phys. Rev. A 104, 043108 (2021) - Published 21 October, 2021

Resolved-sideband cooling is a workhorse technique for a wide range of experiments with trapped ions, atoms, or micromechanical oscillators in the quantum regime. In this work, the authors provide both a novel approach to effectively optimize the cooling sequences using graph theory, as well as a technique to measure the ion temperature more accurately. The procedure should be applicable to any trapped-ion experiment.

IR-photon quenching of delayed electron detachment from hot pentacene anions

S. Iida, S. Kuma, M. Kuriyama, T. Furukawa, M. Kusunoki, H. Tanuma, K. Hansen, H. Shiromaru, and T. Azuma

Phys. Rev. A 104, 043114 (2021) - Published 27 October, 2021

The authors report a detailed study of the spontaneous decay and the laser-induced delayed detachment associated with radiative cooling processes of hot anions of pentacene, a prototypical member of the polycyclic aromatic hydrocarbon (PAH) family of molecules. As an important constituent of interstellar clouds, this molecule is of particular interest to the fields of astrophysics and astrochemistry.

Universal thermodynamics of an SU(N) Fermi-Hubbard model

Eduardo Ibarra-García-Padilla, Sohail Dasgupta, Hao-Tian Wei, Shintaro Taie, Yoshiro Takahashi, Richard T. Scalettar, and Kaden R. A. Hazzard

Phys. Rev. A 104, 043316 (2021) - Published 21 October, 2021

The authors study thermodynamic properties of the SU(N) Fermi-Hubbard model in 2D square lattices and discover simple scaling laws of the energy, the number of on-site pairs, and the kinetic energy with respect to N when the temperature is above the superexchange energy. The results establish a limit to the cooling for SU(N) fermions in 2D, in contrast to the arbitrarily low temperatures that could potentially be achieved in 1D.

Detecting two photons with one molecule

Saumya Biswas and S. J. van Enk

Phys. Rev. A 104, 043703 (2021) - Published 11 October, 2021

Taking inspiration from the human eye, the authors propose using a five-level molecule to detect up to two photons of different frequency that arrive sequentially. They use two formalisms to develop this model: a density-matrix method to achieve analytical results and characterize the proposed detector, and a Hamiltonian method that they show is well suited for numerical calculations.

Phys. Rev. A 104, 043108 (2021) - Published 21 October, 2021

Resolved-sideband cooling is a workhorse technique for a wide range of experiments with trapped ions, atoms, or micromechanical oscillators in the quantum regime. In this work, the authors provide both a novel approach to effectively optimize the cooling sequences using graph theory, as well as a technique to measure the ion temperature more accurately. The procedure should be applicable to any trapped-ion experiment.

The authors report a detailed study of the spontaneous decay and the laser-induced delayed detachment associated with radiative cooling processes of hot anions of pentacene, a prototypical member of the polycyclic aromatic hydrocarbon (PAH) family of molecules. As an important constituent of interstellar clouds, this molecule is of particular interest to the fields of astrophysics and astrochemistry.

Phys. Rev. A 104, 043316 (2021) - Published 21 October, 2021

The authors study thermodynamic properties of the SU(N) Fermi-Hubbard model in 2D square lattices and discover simple scaling laws of the energy, the number of on-site pairs, and the kinetic energy with respect to N when the temperature is above the superexchange energy. The results establish a limit to the cooling for SU(N) fermions in 2D, in contrast to the arbitrarily low temperatures that could potentially be achieved in 1D.

They use two formalisms to develop this model: a density-matrix method to achieve analytical results and characterize the proposed detector, and a Hamiltonian method that they show is well suited for numerical calculations.
