APPLIED PHYSICS B-LASERS AND OPTICS, SPRINGER, 116, 4, 821-829, Sep. 2014, Peer-reviwed, A Bose-Einstein condensate was achieved in a stable magnetic trap on a persistent-supercurrent atom chip with a superconducting closed-loop circuit. We determined precisely the shape of the magnetic trapping potential by systematically controlling the persistent supercurrent. The condensation was verified by time-of-flight imaging and by atom number decay measurements. The measured decay rates agreed quantitatively with numerical simulations on the three-body loss process assuming all of the atoms to be a condensate. We also discuss the feasibility of creating a quasi-one-dimensional Bose gas on our atom chip.

Science, American Association for the Advancement of Science, 341, 6147, 768-770, 2013, Peer-reviwed, The realization of an all-optical transistor, in which one "gate" photon controls a "source" light beam, is a long-standing goal in optics. By stopping a light pulse in an atomic ensemble contained inside an optical resonator, we realized a device in which one stored gate photon controls the resonator transmission of subsequently applied source photons. A weak gate pulse induces bimodal transmission distribution, corresponding to zero and one gate photons. One stored gate photon produces fivefold source attenuation and can be retrieved from the atomic ensemble after switching more than one source photon. Without retrieval, one stored gate photon can switch several hundred source photons. With improved storage and retrieval efficiency, our work may enable various new applications, including photonic quantum gates and deterministic multiphoton entanglement.

Scientific journal, Japanese - Vacuum-Induced Transparency
Haruka Tanji-Suzuki; Wenlan Chen; Renate Landig; Jonathan Simon; Vladan Vuletic
SCIENCE, AMER ASSOC ADVANCEMENT SCIENCE, 333, 6047, 1266-1269, Sep. 2011, Peer-reviwed, Photons are excellent information carriers but normally pass through each other without consequence. Engineered interactions between photons would enable applications as varied as quantum information processing and simulation of condensed matter systems. Using an ensemble of cold atoms strongly coupled to an optical cavity, we found that the transmission of light through a medium may be controlled with few photons and even by the electromagnetic vacuum field. The vacuum induces a group delay of 25 nanoseconds on the input optical pulse, corresponding to a light velocity of 1600 meters per second, and a transparency of 40% that increases to 80% when the cavity is filled with 10 photons. This strongly nonlinear effect provides prospects for advanced quantum devices such as photon number-state filters.

ADVANCES IN ATOMIC, MOLECULAR, AND OPTICAL PHYSICS, VOL 60, ELSEVIER ACADEMIC PRESS INC, 60, 201-237, 2011, Peer-reviwed, Many effects in the interaction between atoms and a cavity that are usually described in quantum mechanical terms (cavity quantum electrodynamics, cavity QED) can be understood and quantitatively analyzed within a classical framework. We adopt such a classical picture of a radiating dipole oscillator to derive explicit expressions for the coupling of single atoms and atomic ensembles to Gaussian modes in free space and in an optical resonator. The cooperativity parameter of cavity QED is shown to play a central role and is given a geometrical interpretation. The classical analysis yields transparent, intuitive results that are useful for analyzing applications of cavity QED such as atom detection and counting, cavity cooling, cavity spin squeezing, cavity spin optomechanics, or phase transitions associated with the self-organization of the ensemble-light system.

Optics, Lasers and Spectroscopy and the Australian Conf., 1196-1198, 2011, Peer-reviwed, Engineered strong photon-photon interactions would enable a broad range of applications in quantum information processing. We demonstrate, using an ensemble of atoms strongly coupled to an optical cavity, that light transmission through an opaque medium may be controlled with a few photons and even with the electromagnetic vacuum field. The vacuum field induces 40% transmission, accompanied by a group delay of 25 ns, which corresponds to the light pulse propagating at 1600 m/s through the medium. The transmission increases to 80% when ∼10 photons are injected into the cavity. The strong optical nonlinearity at a few-photon level observed in this system opens prospects for advanced quantum devices such as photon-number-state filters. © 2011 IEEE.
International conference proceedings, English - Heralded atomic-ensemble quantum memory for photon polarization states
Haruka Tanji; Jonathan Simon; Saikat Ghosh; Benjamin Bloom; Vladan Vuletic
PHYSICA SCRIPTA, IOP PUBLISHING LTD, T135, Jul. 2009, Peer-reviwed, We describe the mapping of quantum states between single photons and an atomic ensemble. In particular, we demonstrate a heralded quantum memory based on the mapping of a photon polarization state onto a single collective-spin excitation (magnon) shared between two atomic ensembles. The polarization fidelity above 90(2)% for any input polarization far exceeds the classical limit of 2/3. The process also constitutes a quantum non-destructive probe that detects and regenerates a photon without measuring its polarization.

PHYSICAL REVIEW LETTERS, AMER PHYSICAL SOC, 103, 4, Jul. 2009, Peer-reviwed, We demonstrate a heralded quantum memory where a photon announces the mapping of a light polarization state onto a single collective-spin excitation (magnon) shared between two atomic ensembles. The magnon can be converted at a later time into a single polarized photon with polarization fidelity over 90(2)% for all fiducial input states, well above the classical limit of 2/3. The process can be viewed as a nondestructive quantum probe where a photon is detected, stored, and regenerated without touching its-potentially undetermined-polarization.

Jonathan Simon; Haruka Tanji; Saikat Ghosh; Vladan Vuletic
NATURE PHYSICS, NATURE PUBLISHING GROUP, 3, 11, 765-769, Nov. 2007, Peer-reviwed, Generation of non-classical correlations (or entanglement) between atoms(1-7), photons(8) or combinations thereof (9-11) is at the heart of quantum information science. Of particular interest are material systems serving as quantum memories that can be interconnected optically(3,6,7,9-11). An ensemble of atoms can store a quantum state in the form of a magnon-which is a quantized collective spin excitation-that can be mapped onto a photon(12-18) with high efficiency(19). Here, we report the phase-coherent transfer of a single magnon from one atomic ensemble to another via an optical resonator serving as a quantum bus that in the ideal case is only virtually populated. Partial transfer deterministically creates an entangled state with one excitation jointly stored in the two ensembles. The entanglement is verified by mapping the magnons onto photons, whose correlations can be directly measured. These results should enable deterministic multipartite entanglement between atomic ensembles.

PHYSICAL REVIEW LETTERS, AMERICAN PHYSICAL SOC, 98, 18, May 2007, Peer-reviwed, We study the performance and limitations of a coherent interface between collective atomic states and single photons. A quantized spin-wave excitation of an atomic sample inside an optical resonator is prepared probabilistically, stored, and adiabatically converted on demand into a sub-Poissonian photonic excitation of the resonator mode. The measured peak single-quantum conversion efficiency of chi=0.84(11) and its dependence on various parameters are well described by a simple model of the mode geometry and multilevel atomic structure, pointing the way towards implementing high-performance stationary single-photon sources.

S Minemoto; H Tanji; H Sakai
JOURNAL OF CHEMICAL PHYSICS, AMER INST PHYSICS, 119, 15, 7737-7740, Oct. 2003, Peer-reviwed, The molecular alignment technique utilizing the interaction between the intense nonresonant laser field and the induced dipole moment is applied to the homonuclear rare gas dimers Rg(2) (Rg=Ar, Kr, and Xe). The degree of alignment is investigated by Coulomb exploding Rg(2) and by measuring the angular distributions of the fragment ions. At the same peak intensity of the laser field, the degree of alignment <cos(2) theta > becomes larger in order of Ar-2, Kr-2, and Xe-2, reflecting the order of magnitudes of their polarizability anisotropy Deltaalpha. By taking I-2 molecules as a reference, Deltaalpha of Ar-2, Kr-2, and Xe-2 are estimated to be 0.5, 0.7, and 1.3 A3, respectively. (C) 2003 American Institute of Physics.

Carbonyl sulfide (OCS) molecules are used as a sample. The degree of orientation can be increased by increasing the peak intensity of the laser field and the magnitude of electrostatic field or by decreasing the initial rotational temperature of the molecules.

JOURNAL OF CHEMICAL PHYSICS, AMER INST PHYSICS, 118, 9, 4052-4059, Mar. 2003, Peer-reviwed, The orientation of polar molecules is demonstrated by the combination of electrostatic and nonresonant, nanosecond Nd:YAG laser fields. The orientation is probed by Coulomb exploding the molecules with a femtosecond laser pulse and detecting the fragment ions with the time-of-flight mass spectrometer. A significant asymmetry is observed in the signal magnitudes of the forward and the backward fragments, which is well explained in terms of the above-mentioned combined-fields scheme proposed by Friedrich and Herschbach [J. Phys. Chem. A 103, 10280 (1999)]. The degree of orientation is enhanced by increasing the peak intensity of the laser field and the magnitude of the electrostatic field, or by lowering the initial rotational temperature. The experimental results obtained are compatible with our numerical simulations. (C) 2003 American Institute of Physics.
