Nature Physics, Published online: 12 May 2022; doi:10.1038/s41567-022-01591-2

Mechanical resonators combined with superconducting circuits are a promising platform for controlling non-classical mechanical states. Here this platform is used to directly measure the parity of a motional quantum state.

The optimal strategy balancing risk and speed predicts DNA damage checkpoint override times

Thu, 12/05/2022 - 00:00

Nature Physics, Published online: 12 May 2022; doi:10.1038/s41567-022-01601-3

Cells have built-in mechanisms for checking for errors during replication, but these checkpoints can slow down reproduction. A theory accounting for optimal checkpoint strategies is presented and tested against observations in budding yeast.

Topological interface of light

Mon, 09/05/2022 - 00:00

Nature Physics, Published online: 09 May 2022; doi:10.1038/s41567-022-01582-3

Upon combining dissipative and nonlinear effects in a bipartite lattice of cavity polaritons, dissipatively stabilized bulk gap solitons emerge, which create a topological interface.

Directional ballistic transport in the two-dimensional metal PdCoO<sub>2</sub>

Mon, 09/05/2022 - 00:00

Nature Physics, Published online: 09 May 2022; doi:10.1038/s41567-022-01570-7

Electrons in PdCoO2 can travel a long way before being scattered, and their band structure is such that they can travel in only one of three directions. As a result, the current flow through this nanoscale conductor can be very efficient.

Gap solitons in a one-dimensional driven-dissipative topological lattice

Mon, 09/05/2022 - 00:00

Nature Physics, Published online: 09 May 2022; doi:10.1038/s41567-022-01599-8

Drive engineering in optical systems can be used to stabilize new nonlinear phases in topological systems. Dissipatively stabilized gap solitons in a polariton lattice establish drive engineering as a resource for nonlinear topological photonics.

High-fidelity three-qubit <i>i</i>Toffoli gate for fixed-frequency superconducting qubits

Mon, 02/05/2022 - 00:00

Nature Physics, Published online: 02 May 2022; doi:10.1038/s41567-022-01590-3

The efficiency of running quantum algorithms can be improved by expanding the hardware operations that a quantum computer can perform. A high-fidelity three-qubit iToffoli gate has now been demonstrated using superconducting qubits.

Where we are with quantum

Thu, 28/04/2022 - 00:00

Nature Physics, Published online: 28 April 2022; doi:10.1038/s41567-022-01597-w

A theoretical analysis shows how a person’s location in space could be verified by the transmission of single photons. A vital application of quantum networks may be within reach.

Thermodynamic equilibrium of optical waves

Thu, 28/04/2022 - 00:00

Nature Physics, Published online: 28 April 2022; doi:10.1038/s41567-022-01607-x

Thermodynamic concepts can be used to understand nonlinear wave systems, but direct evidence for these analogies is scarce. Experiments with multimode fibres have now enabled direct measurement of the thermalization process of optical waves.

A single-qubit position verification protocol that is secure against multi-qubit attacks

Thu, 28/04/2022 - 00:00

Nature Physics, Published online: 28 April 2022; doi:10.1038/s41567-022-01577-0

Unless you are nearby, it is difficult to verify where someone is. Access to a single qubit and classical computation and communication makes it possible to securely check someone’s position as long as adversaries’ quantum resources are limited.

Direct observations of thermalization to a Rayleigh–Jeans distribution in multimode optical fibres

Thu, 28/04/2022 - 00:00

Nature Physics, Published online: 28 April 2022; doi:10.1038/s41567-022-01579-y

Optical nonlinearities in multimodal systems lead to a complex behaviour that can be described as a thermalization process, which is expected to lead to a Rayleigh–Jeans distribution. This process has now been observed in graded-index fibres.

Correlated Hofstadter spectrum and flavour phase diagram in magic-angle twisted bilayer graphene

Mon, 25/04/2022 - 00:00

Nature Physics, Published online: 25 April 2022; doi:10.1038/s41567-022-01589-w

In graphene, the spin and valley degrees of freedom combine into a higher-order isospin. Now, a full map of the phase diagram of this isospin is measured in the moiré bands of twisted bilayer graphene.

Pairing with strings attached

Thu, 21/04/2022 - 00:00

Nature Physics, Published online: 21 April 2022; doi:10.1038/s41567-022-01592-1

Charge carriers in an engineered bilayer Mott insulator are predicted to form tightly bound, mobile pairs, glued together by string excitations of the antiferromagnetic order — a scenario that can be tested with quantum gas microscopy experiments.

Thermopower probes electronic flat bands

Thu, 21/04/2022 - 00:00

Nature Physics, Published online: 21 April 2022; doi:10.1038/s41567-022-01595-y

Heat transport measurements on twisted bilayer graphene reveal a strong asymmetry between electrons and holes — a consequence of band reconstruction, induced by electronic interactions, at partial fillings of the moiré superlattice.

Strong pairing in mixed-dimensional bilayer antiferromagnetic Mott insulators

Nature Physics, Published online: 21 April 2022; doi:10.1038/s41567-022-01561-8

Studies of unconventional pairing mechanisms in cold atoms require ultralow temperatures. Large-scale numerics show that certain bilayer models allow for deeply bound and highly mobile pairs of charges at more accessible temperatures.

Nature Physics, Published online: 21 April 2022; doi:10.1038/s41567-022-01574-3

Thermal transport measurements provide a complementary view of the electronic structure of a material to electronic transport. This technique is applied to twisted bilayer graphene, and highlights the particle–hole asymmetry of its band structure.
