چکیده
∗ Author to whom correspondence should be addressed: [email protected] † Author to whom correspondence should be addressed: [email protected] In the trapped-ion experiment, the squeezing operations are limited to the range of ζX(ζY) ≤ 4 in Eq. (6). Since ÛDok involves the squeezing and inverse squeezing operations, we can freely rescale the squeezing parameters with a single arbitrary constant. In our experiment, we rescale the squeezing parameters by a factor of 1/25, diag(ζX, ζY) = diag(ln( √ ω1/25), ln( √ ω2/25)) for the first squeezing operation and diag(ζ ′ X, ζ ′ Y) = diag(ln( √ ω′ 1/25), ln( √ ω′ 2/25)) for the anti-squeezing in the Eq. (2) of the main text. As discussed in Ref [1], the Doktorov operation ÛDok in Eq. (2) of the main text can be expressed in terms of the ladder operators as

Motional Quantum Error Correction
Is it possible to preserve quantum coherence in systems that are irreversibly coupled to the environment? Apart from being of fundamental interest, this question is of particular significance in the area of quantum information processing [1], where the first two-bit quantum gate operations have been demonstrated in quantum optical systems such as trapped ions [2], and optical cavities [3]. In t...

Dynamical evolution of nonclassical properties in cavity quantum electrodynamics with a single trapped ion
In this paper, by considering a system consisting of a single two-level trapped ion interacting with a single-mode quantized radiation field inside a lossless cavity, the temporal evolution of the ionic and the cavity-field quantum statistical properties including photon-counting statistics, quantum fluctuations of the field quadratures and quantum fluctuations of the ionic dipole variables are...
متن کاملReconstructing the vibrational state of a trapped ion.
A new approach for reconstructing the vibrational quantum state of a trapped ion is proposed. The method rests upon the current ability of manipulating the trapped ion state and on the possibility of effectively measuring the scalar product of the two vibrational cofactors of a vibronic entangled state. The experimental feasibility of the method is briefly discussed.

Many applications in the life-sciences demand non-contact manipulation tools for forceful but nevertheless delicate handling of various types of sample. Moreover, the system should support high-resolution optical imaging. Here we present a hybrid acoustic/optical manipulation system which utilizes a transparent transducer, making it compatible with high-NA imaging in a microfluidic environment....
