High-fidelity preparation, gates, memory and readout of a trapped-ion quantum bit
T. P. Harty, D. T. C. Allcock, C. J. Ballance +5
We implement all single-qubit operations with fidelities significantly above the minimum threshold required for fault-tolerant quantum computing, using a trapped-ion qubit stored i…
Large 2D Coulomb crystals in a radio frequency surface ion trap
B. Szymanski, R. Dubessy, B. Dubost +3
We designed and operated a surface ion trap, with an ion-substrate distance of 500\mum, realized with standard printed-circuit-board techniques. The trap has been loaded with up to…
Double-lambda microscopic model for entangled light generation by four-wave-mixing
Q. Glorieux, R. Dubessy, S. Guibal +4
Motivated by recent experiments, we study four-wave-mixing in an atomic double-Λ system driven by a far-detuned pump. Using the Heisenberg-Langevin formalism, and based on the micr…
Topologically decoherence-protected qubits with trapped ions
Pérola Milman, Wilfried Maineult, Samuel Guibal +4
We show that trapped ions can be used to simulate a highly symmetrical Hamiltonian with eingenstates naturally protected against local sources of decoherence. This Hamiltonian invo…
