Entanglement is an important resource in quantum-enhanced technologies, but it is difficult to generate, especially in solid-state systems. An experiment now demonstrates the entanglement of two nuclear spins via a parity measurement of the electron spin in a nitrogen-vacancy centre in diamond. 
Quantum information: Violation of Bell's inequality in Si.
An entangled state of two spin qubits in silicon has been prepared and measured, yielding a violation of Bell's inequality that is the largest achieved in the solid state so far.
Manipulating a qubit through the backaction of sequential partial measurements and real-time feedback
Quantum measurements affect the state of the system, so they can be used both as probe and control knob. This idea is demonstrated in an experiment with nuclear spin qubits in diamond that are

Nitrogen atoms trapped tens of nanometres apart in diamond can now be linked by quantum entanglement. This ability to produce and control entanglement in solid systems could enable powerful quantum
Generation and stabilization of Bell states via repeated projective measurements on a driven ancilla qubit
A protocol is proposed to generate Bell states in two non-directly interacting qubits by means of repeated measurements of the state of a central ancilla connected to both qubits. An optimal
