Entanglement detection (2008, background): “Therefore, many experiments aim at the generation of GHZ states, and GHZ states with up to ten qubits have already been prepared using ions [7,207,208] or photons [9,10,201,209–211].”
Collective strong coupling with ion Coulomb crystals in an optical cavity (2009, background): “is most promising, with the furthest advances having been made with trapped ion”
A coherent all-electrical interface between polar molecules and mesoscopic superconducting resonators (2006, background): “with the ability to move them with electric fields, as with ion”

A quantum spin transducer based on nanoelectromechanical resonator arrays (2009, methodology): “The spin is controlled by local microwave fields of frequency ωmw and described by the Hamiltonian Hs i(t )= h̄(δiσz i + i(t )σx i)/2, where σx,y,z i are Pauli operators, i is the microwave Rabi frequency and δi = ω0 − ωmw.”
Realization of a Quantum Integer-Spin Chain with Controllable Interactions (2014, methodology): “Our implementation of a decoherence-protected subspace is closely analogous to techniques that have been used for extending the coherence time of certain spin-1=2 quantum simulations [45], and for creating a logical qubit that is robust to environmental perturbations [48], for which a universal gate”
Efficient Long-Range Entanglement Using Dynamic Circuits (2023, background): “5 [40], within a confidence interval of 95% up to 7 qubits with a rapid decay in fidelity with increasing system size mainly due to errors in two-qubit gates and ZZ crosstalk errors during idling time [41].”
Experimental demonstration of a hyper-entangled ten-qubit Schr\ (2008, background): “To date, entangled states up to six (4), eight (5) atoms, or six photonic qubits (6) have been demonstrated.”
