Optimal simulation of quantum dynamics

Nature Physics, Published online: 08 August 2022; doi:10.1038/s41567-022-01696-8

Tensor networks are mathematical structures that efficiently compress the data required to describe quantum systems. An algorithm for the optimal simulation of quantum dynamics based on tensor networks has now been implemented on a trapped-ion processor.

Observing the effect of nuclear motion on attosecond charge migration

Δευ, 08/08/2022 - 00:00

Nature Physics, Published online: 08 August 2022; doi:10.1038/s41567-022-01727-4

Attosecond charge migration in a neutral molecule has been observed to decohere within approximately 10 fs. However, this does not mean that the electronic coherence is irreversibly lost, as the charge migration is observed to revive after 40–50 fs. These findings have the potential to enable laser control of photochemical processes.

Nature Physics, Published online: 04 August 2022; doi:10.1038/s41567-022-01689-7

The simulation of quantum dynamics is a challenging task to solve with classical resources. An experiment with a trapped-ion quantum processor now shows the efficient simulation of the evolution of large-scale many-body quantum systems.

Decoherence and revival in attosecond charge migration driven by non-adiabatic dynamics

Nature Physics, Published online: 04 August 2022; doi:10.1038/s41567-022-01690-0

X-ray ultrafast transient absorption spectroscopy captures the charge migration in neutral silane molecules, which shows in the spectra as pairs of quantum beats.

Sustained unidirectional rotation of a self-organized DNA rotor on a nanopore

Nature Physics, Published online: 04 August 2022; doi:10.1038/s41567-022-01683-z

A self-assembled DNA structure is coupled to a nanopore and exhibits continuous rotation in the presence of nanoscale flows driven by electric fields or ionic gradients.

Two qubits for the price of one ion

Nature Physics, Published online: 01 August 2022; doi:10.1038/s41567-022-01713-w

Trapped ion quantum computers can use two different kinds of ion to avoid crosstalk between adjacent qubits. Encoding two different qubit types in only one ion species can achieve the same goal while reducing experimental complexity.

Intrinsic magnetism in superconducting infinite-layer nickelates

Nature Physics, Published online: 01 August 2022; doi:10.1038/s41567-022-01684-y

Measurements of four different infinite-layer nickelates show that magnetic behaviour coexists with superconductivity. This is different from what is seen in cuprates, giving a strong distinction between the two classes of oxide superconductors.

Realizing coherently convertible dual-type qubits with the same ion species

Nature Physics, Published online: 01 August 2022; doi:10.1038/s41567-022-01661-5

Quantum computing with trapped ions requires qubits that can store and manipulate quantum information, and others that can be used for destructive incoherent operations. Different states of ytterbium-171 ions can be used to realize both qubit types

Classically verifiable quantum advantage from a computational Bell test

Nature Physics, Published online: 01 August 2022; doi:10.1038/s41567-022-01643-7

Interactive protocols can verify that a quantum computer exhibits a computational speedup using only classical analysis of its output. Exploiting a connection to Bell’s theorem gives a simpler protocol that is much less demanding for experiments.

20 years of network community detection

Nature Physics, Published online: 29 July 2022; doi:10.1038/s41567-022-01716-7

A fundamental technical challenge in the analysis of network data is the automated discovery of communities — groups of nodes that are strongly connected or that share similar features or roles. In this Comment we review progress in the field over the past 20 years.
