NOON States of Nine Quantized Vibrations in Two Radial Modes of a Trapped Ion

Junhua Zhang, Mark Um, Dingshun Lv +3 more

We develop a deterministic method to generate and verify arbitrarily high NOON states of quantized vibrations (phonons), through the coupling to the internal state. We experimentally create the entangled states up to N=9 phonons in two vibrational modes of a single trapped ^{171}Yb^{+} ion. We observe an increasing phase sensitivity of the generated NOON state as the number of phonons N increases and obtain the fidelity from the contrast of the phase interference and the population of the phonon states through the two-mode projective measurement, which are significantly above the classical bound. We also measure the quantum Fisher information of the generated state and observe Heisenberg scaling in the lower bounds of phase sensitivity as N increases. Our scheme is generic and applicable to other photonic or phononic systems such as circuit QED systems or nanomechanical oscillators, which have Jaynes-Cummings-type of interactions.

High NOON states in trapped ions

D. Rodríguez-Méndez, H. M. Moya-Cessa

We show how NOON states may be generated in ion traps. We use the individual interactions of light with each of the two vibrational modes of the ion to entangle them. This allows us to generate NOON states with N =8.

Creation of arbitrary Dicke and NOON states of trapped-ion qubits by global addressing with composite pulses

Svetoslav S. Ivanov, Nikolay V. Vitanov, Natalia Korolkova

We propose a fast and efficient technique to create classes of highly entangled states of trapped ions, such as arbitrary Dicke states and superpositions of them, e.g. NOON states. The ions are initialized in the phonon ground state and are addressed globally with a composite pulse that is resonant with the first motional sideband. The technique is fairly robust to parameter fluctuations and operates on comparatively short time scales, as resonant interactions allow one to use the minimum laser pulse area. The number of single pulses from the composite sequence is equal to the number of ions; thus the implementation complexity grows only linearly with the size of the system. The approach does not require individual addressing of the ions in the trap and can be applied both inside and outside the Lamb–Dicke regime.
