Electrically tuned spin–orbit interaction in an InAs self-assembled quantum dot

The strength of the interaction between the spin state and orbital motion of electrons in a semiconducting quantum dot can be controlled by electrical gates.

Cooper pair splitting in parallel quantum dot Josephson junctions

Spin-entangled electron pairs are one possible resource for future solid-state quantum information processing systems. Here, the authors directly prove spin entanglement between two electrons that had previously been a Cooper pair in a superconducting lead but were split using two quantum dots.

Noise-correlation spectrum for a pair of spin qubits in silicon

Errors in a quantum computer that are correlated between different qubits pose a considerable challenge for correction schemes. Measurements of noise in silicon spin qubits show that electric field fluctuations can create strongly correlated errors.

Quantum non-demolition readout of an electron spin in silicon

Conventional qubit readout methods in silicon spin qubits destroy the quantum state, precluding any further computations based on the outcome. Here, the authors demonstrate quantum non-demolition readout using a second qubit of the same kind, making for a scalable approach.

A fast quantum interface between different spin qubit encodings

The race to produce a quantum computer has driven the development of many different qubit designs with different benefits and drawbacks. Noiri et al. demonstrate a hybrid device with two coupled semiconductor spin qubits of different designs, which should allow each qubit’s advantages to be exploited.

Electrically driven single-electron spin resonance in a slanting Zeeman field

The integration of a micrometre-sized magnet with a semiconductor device has enabled the individual manipulation of two single electron spins. This approach may provide a scalable route for quantum computing with electron spins confined in quantum dots.

Trilayer graphene is a semimetal with a gate-tunable band overlap

The electronic properties of graphene samples containing three layers of carbon atoms are significantly different from those of single-layer and bilayer graphene. Trilayer graphene is a semimetal and, unlike other materials, the overlap between the conduction and valence bands can be electrostatically controlled.

4π-periodic Josephson supercurrent in HgTe-based topological Josephson junctions

A material weakly linking two superconductors may itself exhibit superconductivity whilst its material properties strongly influence the nature of the supercurrent. Here, the authors identify a supercurrent with p-wave symmetry in such a Josephson junction made of topologically non-trivial material.

Generation and detection of pure valley current by electrically induced Berry curvature in bilayer graphene

Bilayer graphene can host topological currents that are robust against defects and are associated with the electron valleys. It is now shown that electric fields can tune this topological valley transport over long distances at room temperature.
