LTC Seminar LTClogoMedKat3 Title: Hybrid quantum circuit with a superconducting qubit coupled to a spin ensemble Speaker: Patrice Bertet, CEA, Saclay, France Time: Tuesday, January 31, 2012 at 15:15 Place: 1520-732 Abstract: We report the experimental realization of a hybrid quantum circuit combining a superconducting qubit and an ensemble of electronic spins. The qubit, of the transmon type, is coherently coupled via a frequency-tunable superconducting resonator to the spin ensemble which consists of nitrogen-vacancy (NV) centers in a diamond crystal [1]. Using this circuit, we prepare arbitrary superpositions of the qubit states that we store into collective excitations of the spin ensemble and retrieve back into the qubit [2]. These results constitute a first proof of concept of a spin-ensemble based quantum memory for superconducting qubits. [1] Y. Kubo et al., Phys. Rev. Lett. 105, 140502 (2010). [2] Y.

QUANTUM OPTICS SEMINAR Title: Mixture of Rubidium- Lithium Degenerate Bose and Fermi Gasses Speaker: Subhadeep De Joint Quantum Institute (JQI), University of Maryland (UMD) and National Institute for Standards and Technology (NIST), Maryland, USA Time: Tuesday, January 31 at 10:15 Room: 1525-323 Abstract: Ultracold mixtures of bosons and fermions are of interest for studying superfluid properties of coupled fermions and other many-body phenomena in the presence of impurity bosons in a fermionic bath or the reverse. Attractive interaction among spin polarized fermions induced by density fluctuation in the degenerate bosons forms phonon induced pairing in fermions, which is alike to cooper pair. Such a system might resolve the dynamics of p-wave superconductivity. Ultracold heteronuclear polar molecules in their ro-vibrational ground state are objects of interest for precision measurements of fundamental constants, parity and time reversal symmetry violation. An array of such polar molecules stored in an optical lattice opens up possibility to serve as quantum bits. Their long range dipole-dipole interaction is particularly of interest to study novel quantum phases with atoms stored in optical lattice. As for example 87Rb -6Li (Rubidium-Lithium) heteronuclear molecules acquire a large permanent electric dipole moment of 4.2 Debye, and are interesting gas mixtures from molecular point of view. We show a new way of coupling distant bosons due to successive scattering of spin polarized fermions, which has R-4 spatial dependence. Unlike the dipole-dipole interaction, the strength of the fermion mediated Bose-Bose interaction can be either attractive or repulsive with the help of interspecies Feshbach resonances. The loss process due to three-body recombination will greatly be suppressed in the Mott phase of bosons. A mixture of heavy bosons and light fermions is ideal because a lattice will localize bosons while fermions can move freely. We propose to use a spin-polarized, non-interacting, degenerate 6Li gas mixed with 87Rb atoms. The fermion mediated Bose-Bose coupling is tunable using a 87Rb-6Li Feshbach resonance. We further investigate schemes to create supersolid phase and quantum magnetism in bosons with the help of the fermion mediated interactions. We are engaged in building an apparatus to produce mixtures of 87Rb Bose Einstein condensates (BEC) and degenerate Fermi gasses (DFG) of 6Li simultaneously. The ultracold bosons will initially be used for sympathetic cooling of fermions to reach the degeneracy. Currently the machine is commissioning the BEC and DFG is in the pipeline. We are engaged in studying many-body dynamics associated to 87Rb spinor BEC in the F = 1 hyperfine state. I will discuss the ongoing physics project with BEC that we are working on in parallel to building systems for fermions and long term goals that will be perused with the 87Rb-6Li mixtures.

[vip-all] Nyt om ferieregistrering/ News on holiday registration
by Ruth Laursen 25 Jan '12

25 Jan '12

Den 1. februar 2012 overgår instituttet til elektronisk registrering af ferie og alt andet fravær. Det betyder, at det fra den dato er medarbejderen selv, der skal foretage disse registreringer. Vi har udarbejdet såvel en dansk som en engelsk vejledning til registreringen, se link nedenfor. Vejledningen ligger desuden på instituttets hjemmeside under Medarbejderinformation. http://phys.au.dk/fileadmin/site_files/intern/Registrering_af_ferie_og_frav… En del af vore forskere er vant til at bede deres sekretær holde styr på dette, og det kan I naturligvis fortsat gøre, såfremt I har brug for det. Såvel Trine Binderup som jeg selv besvarer gerne eventuelle spørgsmål. ************************************************************* As of 1 February 2012 the Department implements electronic registration of holidays and other types of absence. As an effect, each employee has to register his/her own holidays and absence. For Danish or English registration guidelines, see the links below. You may also find the guidelines on the Department homepage under Information for employees. http://phys.au.dk/fileadmin/site_files/intern/Registration_of_holidays_and_… <http://phys.au.dk/fileadmin/site_files/intern/Registration_of_holidays_and_…> Some of our researchers have previously asked their secretary to assist them register their holidays, which they, of course, may continue to do. If you have any questions, please do not hesitate to contact Trine Binderup or me. ******************************* Ruth Laursen Head of Department Secretariat Department of Physics and Astronomy Aarhus University Ny Munkegade 120 8000 Aarhus C Denmark e-mail: ruth(a)phys.au.dk Office: 1522-212 Mobile: + 45 2338 2335 Telephone: +45 8715 5652

[vip-all] Info-skærme på IFA.
by Mette Alstrup Lie 25 Jan '12

25 Jan '12

Kære alle. Info-skærme monteres på IFA torsdag den 2. februar. På alle etager 1-7 placeres en skærm mellem elevatordørene med visning af kalenderen. På 1. og 2. etage placeres desuden en touch-skærm, der viser nyheder fra instituttet, inkl. abstracts til seminarer, kollokvier, etc. Desuden monteres både en kalender- og en nyheds-skærm på 3. etage i rummet umiddelbart før Fysisk Auditorium. Info-skærmene skal erstatte opslagstavlerne mellem elevatordørene, som fjernes mandag den 30. januar. *Annoncering i perioden fra mandag til torsdag i næste uge foregår derfor ved at sende en mail til mig (lie(a)phys.au.dk) hvorefter jeg vil informere instituttet. * Opslagstavlerne til studenteropslag fjernes ikke i denne omgang. Proceduren for annoncering på info-skærmene udsendes umiddelbart før montering. Venlig hilsen Mette. -- Mette Alstrup Lie Department of Physics and Astronomy Aarhus University Ny Munkegade 120 DK-8000 Aarhus C Denmark Office 1522-214 e-mail:lie@phys.au.dk Tel: +45 8715 5607 Mobile: +45 2165 4361
