  • In silicon, quantum information can be stored in donors or quantum dots, each with its advantages and limitations—particularly in terms of fabrication. Here the authors coherently couple a phosphorous donor’s electron spin to a quantum dot, encoding information in the hybrid two-electron system’s state.

  • Coupling semiconductor spin qubits over long distances using a superconducting resonator makes different quantum architectures possible. Now, the coherent swapping of quantum states has been observed between qubits coupled using this design.

  • As the performance of silicon-based qubits has improved, there has been increasing focus on developing designs that are compatible with industrial processes. Here, Jock et al. exploit spin-orbit coupling to demonstrate full, all-electrical control of a metal-oxide-semiconductor electron spin qubit.

  • Hole spins in SiGe quantum dot arrays are a promising qubit platform, but suffer from gate-induced electrostatic disorder, drift and hysteresis. Here, Hall bar and quantum dot Ge/SiGe heterostructures are studied, obtaining a model for gate hysteresis and its effect on transport and charge noise.
