Hybrid quantum logic and a test of Bell's inequality using two different atomic isotopes
C. J. Ballance, V. M. Schaefer, J. P. Home +9
Entanglement is one of the most fundamental properties of quantum mechanics, and is the key resource for quantum information processing. Bipartite entangled states of identical par…
Quantum harmonic oscillator state synthesis by reservoir engineering
D. Kienzler, H. -Y. Lo, B. Keitch +6
The robust generation of quantum states in the presence of decoherence is a primary challenge for explorations of quantum mechanics at larger scales. Using the mechanical motion of…
Quantum control of the motional states of trapped ions through fast switching of trapping potentials
J. Alonso, F. M. Leupold, B. C. Keitch +1
We propose a new scheme for supplying voltages to the electrodes of microfabricated ion traps, enabling access to a regime in which changes to the trapping potential are made on ti…
Memory coherence of a sympathetically cooled trapped-ion qubit
J. P. Home, M. J. McDonnell, D. J. Szwer +4
We demonstrate sympathetic cooling of a 43Ca+ trapped-ion "memory" qubit by a 40Ca+ "coolant" ion near the ground state of both axial motional modes, whilst maintaining coherence o…
Long-lived mesoscopic entanglement outside the Lamb-Dicke regime
M. J. McDonnell, J. P. Home, D. M. Lucas +7
We create entangled states of the spin and motion of a single Ca ion in a linear ion trap. The motional part consists of coherent states of large separation and long coh…
Deterministic entanglement and tomography of ion spin qubits
J. P. Home, M. J. McDonnell, D. M. Lucas +7
We have implemented a universal quantum logic gate between qubits stored in the spin state of a pair of trapped calcium 40 ions. An initial product state was driven to a maximally…
