  • Future quantum communication technologies require entanglement between stationary and flying qubits, in systems that are inherently scalable. To this end, De Greveet al.present full state tomography of a qubit pair formed by entangling a quantum dot spin and a photon, with a fidelity of over 90%.

  • Semiconductor spin qubits are widely viewed as a promising route to scalable quantum computing. This Review evaluates integration challenges across the quantum–classical stack and discusses how established semiconductor design principles could underpin industrial-scale, fault-tolerant quantum computing.

  • Scanning electron microscopy is used to image stacking domains in few-layer graphene, as well as moiré patterns in twisted van der Waals heterostructures, allowing for the correlation of the local structure with their excitonic properties.

  • An ultrafast, all-optical spin echo technique is used to increase the decoherence time of a single quantum dot electron spin from nanoseconds to several microseconds. The ratio of decoherence time to gate time exceeds 105, suggesting strong promise for future photonic quantum information processors and repeater networks.

  • Electron spin in quantum dots are extensively studied as a qubit for quantum information processing. However, the coherence of electron spin is deleteriously influenced by nuclear spin. Quantum-dot holes are a potential alternative. Full control over hole-spin qubits is now achieved using picosecond lasers.

  • Entanglement of the spin of an electron in a semiconductor quantum dot with a single photon is reported, and verified by means of time-resolved frequency downconversion to a telecommunications wavelength; this process is an essential requirement for future quantum networks.
