3 Rydberg atoms P. Schauß et al, Nature 491, 87 (2012). Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

4 Rydberg atoms Rydberg atom A Rydberg atom is an excited atom with an electron in a state with a very high principal quantum number n 50. Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

5 Rydberg atom Distinctive properties of Rydberg states: an enhanced response to electric and magnetic field long decay times electron wavepackets move along classical orbits excited electron experiences Coulomb electric potential radius of an orbit scales as n 2 energy level spacing decreases as 1/n 3 Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

6 Interactions between Rydberg atoms Transition dipole moment to nearby states scales as n 2 Strong dipole-dipole interactions The interaction strength rapidly increases with n; The strength of interactions for n 100 can be comparable to the strength of the Coulomb interaction between ions. Can be used for engineering of desired many-particle states. Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

7 Interactions between Rydberg atoms Interactions depend on the distance as: in the van der Waals regime in the dipole-dipole regime 1/R 6 1/R 3 Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

8 Consequences of interactions Strong long-range interactions lead to cooperative effects such as: superradiance dipole blockade. May provide a basis for applications such as single-photon sources and quantum gates. Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

9 Dipole blockade If one atom is excited into the Rydberg state strong interaction shifts the resonance frequencies of all the surrounding atoms suppressing their excitation. Rydberg blockade can be applied in quantum information processing non-linear quantum optics using Rydberg EIT Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

10 Slow light Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

12 Three level Λ system Dark state D Ω c g Ω p s Transitions g e and s e interfere destructively Cancelation of absorbtion Electromagnetically induced transparency EIT Very fragile Very narrow transparency window Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

13 Slow light Narrow transparency window ω 1 MHz Very dispersive medium Small group velocity slow light Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

14 Rydberg EIT A weak probe field E is coupled to Rydberg levels by a strong control field Ω. Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

15 Rydberg EIT A weak probe field E is coupled to Rydberg levels by a strong control field Ω. Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

16 Rydberg EIT A weak probe field E is coupled to Rydberg levels by a strong control field Ω. Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

17 Rydberg EIT EIT atom-light interactions without absorption Rydberg states strong long-range atom-atom interactions As a result photon-photon interactions. Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

18 Rydberg EIT For a single incident probe photon the control field induces a transparency in a narrow spectral window via EIT probe photon is coupled to Rydberg excitation forming a combined quasiparticle Rydberg polariton Rydberg polariton propagates at a reduced speed c Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

19 Rydberg EIT When two probe photons propagate in the Rydberg medium strong interaction between two Rydberg atoms tunes the transition out of the resonance destroying the transparency and leading to absorption. Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

20 Experimental realization of quantum nonlinear optics A. V. Gorshkov et al, Phys. Rev. Lett. 107, (2011). T. Peyronel et al, Nature 488, 57 (2012). 46 n 100 Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

21 Disadvantage of Rydberg EIT Only one photon propagates without absorption in the Rydberg blockade region. All additional photons are absorbed leading to losses Our proposal To use atom-atom interactions during light storage. Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

22 Storing of slow light Hau et al, Nature, 2001 Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

23 Storing of slow light Dark state D g Ω p Ω c s Information on probe beam is contained in the atomic coherence Storing of light switching off control beam; information about light is retained in the atomic coherence Releasing switch on control beam Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

24 Storing of slow light Initial storage times (L. V. Hau et al, Nature 2001): 1 ms Now achievable storage time 1 min G. Heize et al, Phys. Rev. Lett. 111, (2013). Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

25 Storing slow light using two Rydberg states J. Ruseckas, I. A. Yu, and G. Juzeliūnas, in preparation Ladder scheme with the Rydberg state s Storing procedure: 1 Probe field is stored in a coherence between ground state g and Rydberg state s 2 π/2 pulse is applied converting the Rydberg state s to a supperposition of s and p Rydberg states + = 1 2 ( s + p ) Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

26 Stored Rydberg slow light Resonance dipole-dipole interaction between Rydberg atoms V Exchange of the s and p Rydberg states. During the storage correlated pairs of atoms are created in the initially not populated state = 1 2 ( s p ) Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

27 State of atoms at the end of storage period Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

28 Stored Rydberg slow light At the end of the sorage a second π/2 pulse is applied, converting the state into Rydberg state s and state + into state p. Excitations in the s state are converted into the probe photons, p state excitations remain in the medium. Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

29 Consequences No regenerated slow light without interaction between the atoms Restored probe beam contains correlated pairs of photons Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

30 Second-order correlation function Second-order correlation function: g (2) (τ) = E (t)e (t + τ)e(t + τ)e(t) E (t)e(t) E (t + τ)e(t + τ) Can be measured using the Hanbury-Brown and Twiss detection scheme Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

31 Second-order correlation function of the restored light We assume r c r Ry, where r c is a characteristic interaction distance: V (r c )T = 1 r Ry is a mean distance between Rydberg atoms Second order correlation function of the restored light For small storage time T g (2) out (τ) 1 cos[v (v g0τ)t ] g (2) out (τ) [V (v g0τ)t ] 2 Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

32 Second-order correlation function of the restored light g (2) out (τ) [V (v g0τ)t ] 2 Allows to measure interaction potential Corrections due to the finite spectral width of EIT (see red dashed curve) Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

33 Influence of slow light losses The restored light acquires a finite spectral width ω out v g0 /r c, which leads to a finite life-time of the dark state polariton, τ 1 pol = 2Γ( ω out/ω c ) 2. This distorts short time behaviour of g (2) out (τ). Julius Ruseckas (Lithuania) Rydberg slow light April 28, / 33

34 Summary Two-photon states can be created by properly storing and retrieving the slow light in the medium of Rydberg atoms The second-order correlation function of the restored light is determined by the atom-atom interactions during the storage. Measurement of the restored light allows one to probe interactions in many-body systems using optical means. Sensitivity of such measurements can be increased by increasing the storage time.
