    Little is known about how edge states in topological materials interact with each other. Here, a quantum spin Hall insulator is used to show that when edge states are brought close together, additional gaps appear in the spectrum.

    Non-Hermitian systems with gain and loss give rise to exceptional points with exceptional properties. An experiment with superconducting qubits now offers a first step towards studying these singularities in the quantum domain.

    The back-action of electrons can cool a nanomechanical oscillator to a few-quantum state when a current flows through a suspended nanotube. The electron back-action, which is attributed to an electrothermal effect, also induces self-oscillations.

    Superconducting quantum interference devices can accurately measure temperatures even below 1 mK, but there’s more to them — as Thomas Schurig explains.

    Floquet engineering harnesses alternating fields to create a topological band structure in an otherwise ordinary material. These fields drive plasmons that can spontaneously split into chiral circulating modes and induce magnetization.

    The measured change in the fundamental frequency of a superconducting resonator coupled to a tunnel junction reveals a broadband constant Lamb shift, which is typically inaccessible in atomic systems.

    Spin current is generated by pumping from nuclear spin waves. The nuclear magnetic resonance is used to transfer angular momentum from the nuclei of an antiferromagnet to a propagating spin current that is subsequently collected in a distant electrode.

    The entropy of a few-electron quantum system is measured for the first time by tracking the movement of charge in and out of the system. This could allow the unambiguous detection of Majorana fermions in solid state devices.

    Fluid transport at the nanoscale is important for understanding a range of phenomena in biological and physical systems. A theory accounting for transport through fluctuating channels is presented, providing a framework for designing active membranes.

    Energy levels in superconducting quantum devices are highly sensitive to charge fluctuations. Generally, this is considered a bug, but new work transforms this sensitivity into the defining feature of a novel device.

    It’s still unclear which problems can be solved by near-term quantum computers that are beyond the reach of their classical counterparts. A new analysis makes a practical assessment of how sampling the output of a quantum circuit leaves supercomputers in the dust.

    The charge–phase duality in superconductors implies that the well-known SQUID has an analogue based on the interference of fluxons. Such a ‘charge quantum interference device’ (or CQUID) has now been experimentally demonstrated.

    Quantized Majorana conductance is a hallmark of topological superconductors, but its fragility has made it difficult to observe. Device improvements have now enabled its measurement, making everyone eager to see the next step — topological qubits.

    Device-independent quantum cryptography promises unprecedented security, but it is regarded as a theorist's dream and an experimentalist's nightmare. A new mathematical tool has now pushed its experimental demonstration much closer to reality.

    As we move beyond the twentieth anniversary of the teleportation of a quantum state, it's clear that the coming years will be just as fruitful.

    A study of the strong coupling of different exciton species in two-dimensional molybdenum diselenide in a cavity uncovers the rich many-body physics and may lead to new devices.

    A type of optics experiment called a boson sampler could be among the easiest routes to demonstrating the power of quantum computers. But recent work shows that super-classical boson sampling may be a long way off.

    A crystalline organic semiconductor that combines the long spin-relaxation times of organic semiconductors with the high charge-carrier mobilities typically found in inorganic semiconductors provides unprecedented prospects for organic spintronics.

    Semiconductor nanowires with superconducting leads are considered promising for quantum computation. The current–phase relation is systematically explored in gate-tunable InAs Josephson junctions, and is shown to provide a clean handle for characterizing the transport properties of these structures.

    Physical rotation can create fictitious magnetic fields, a phenomenon that stems from Larmor's theorem. The effect on a nuclear spin ensemble was measured using the spin–echo of nitrogen–vacancy centres in rapidly spinning diamond. Interestingly, the rotationally induced magnetic fields can cancel a conventional magnetic field for the nuclear spins.

    An excited two-level system emits a single photon, but in special circumstances it can emit two. The reason for this unexpected two-photon emission lies with modified Rabi oscillations.

    Photoemission is usually driven by the energy of the illuminating laser pulses, but in the strong-field regime, the photoemission from an array of plasmonic nanoparticles is shown to be controlled by the light’s electric field.

    Single atoms on a surface can be useful in spintronics applications, but their spin lifetime is limited by relaxation. By cleverly employing an STM tip, one can probe the spin dynamics and disentangle different effects leading to relaxation.
