Two-Photon Coherent Control of Atomic Collisions by Light with Entangled Polarization

Abstract

We describe a new method of coherent optical control of internal dynamics of atomic collisions by means of two correlated light beams having entangled polarizations. We show that, if excitation of a colliding pair of atoms is by two photons having entangled polarizations, it is possible to redirect the output fragments of the collision into certain channels with a selected type of internal transition symmetry. The transition symmetry is defined in the body-fixed coordinate frame which has random and originally unknown orientation in space.

Polarization-sensitive coherent control of atomic collisions with nonclassical light

Dmitriy V. Kupriyanov, Igor M. Sokolov, A. V. Slavgorodskii

In this paper we consider the mechanism of coherent control of atomic collisions by two-photon excitation of colliding atoms with nonclassical light characterized by polarization entanglement. Such modification of the well-known optical-collision method is proposed as a possible spectroscopic application of nonclassical light for study of collisional dynamics. We show that quantum correlations allow one to have a deeper control of the internal dynamics of atomic collision than do the principles of classical statistics. Our qualitative discussion is supported by numerical calculations made for ${}^{1}{S}^{1}{P}^{1}S$ optical transition of Mg perturbed by collisions with rare-gas atom.

Quantum control of entangled photon-pair generation in electron-atom collisions driven by laser-synthesized free-electron wave packets

R. Esteban Goetz, Klaus Bartschat

We propose an extension of coherent control using laser-synthesized free-electron matter waves. In contrast to coherent control schemes exploiting optical coherences to steer the dynamics of matter waves, we analyze the opposite and investigate the control of quantum light emission driven by laser-sculpted coherent free-electron matter waves. We apply this concept to the control of entangled photon-pair emission in electron-atom collisions, in which the incident electron wave packet, colliding with a target atom $B$, is engineered by interferometric resonantly enhanced multiphoton ionization of a parent atom $A$. Each ionization pathway leads to electron wave packets that coherently interfere during temporal evolution in the continuum. Their mutual coherence can be controlled by adjusting the relative phases or time delays of the frequency components of the ionizing field contributing to the interfering pathways. We report coherent control of entangled photon-pair generation in radiative photocascade emission upon decay of the target atom after inelastic excitation triggered by the collision with the synthesized electron wave packet.

Quantum control of entangled photon-pair generation in electron-atom collisions driven by multiphoton-tailored free-electron wave packets

R. Esteban Goetz, Klaus Bartschat

Two-pathway coherent control of photoionization is an example of control of matter waves using light. Here, we analyze the opposite and investigate the control of quantum light using matter waves. We report coherent control of entangled photon-pair emission in electron-atom collisions mediated by transfer of the temporal and atomic coherence carried by the incident electron wave packet. The latter is engineered by resonantly-enhanced multiphoton ionization exploiting interfering ionization pathways. We show that both sources of coherence can be used to control the angular distributions of photons emitted by radiative cascade upon optical decay in the target atom, offering the possibility of coherent control driven by sculpted matter waves via transfer of optical and atomic coherence.

Generation and communication of photon-photon and atom-atom entangled states

Gershon Kurizki, Inbal Friedler, David Petrosyan

We introduce and discuss two schemes for generation and transfer of photon-photon and atom-atom entanglement. First we propose a method to achieve a large conditional phase shift of a probe field in the presence of a single-photon control field whose carrier frequency is within the photonic band gap created by spatially-periodic modulation of the electromagnetically induced transparency resonance. Then we present the concept of a reversible transfer of the quantum state of two internally-translationally entangled fragments, formed by molecular dissociation, to a photon pair. Our scheme allows, in principle, high-fidelity state transfer from the entangled dissociated fragments to light, thereby producing a highly correlated photon pair. This process can be followed by its reversal at a distant node of a quantum network resulting in the recreation of the original two-fragment entangled state. The proposed schemes may have advantageous applications in quantum teleportation, cryptography, and quantum computation.

Generating and controlling chains of entangled atoms by coherent control techniques

Moshe Shapiro

A practical way of writing long sequences of entangled atomic qubits using coherent control with classical light sources is proposed. The method utilizes one-photon vs two-photon interference as a means of controlling the directionality of the motion of valence electrons during molecular dissociation processes. We show that, by dissociating in an optical lattice a one-dimensional array of ultracold diatomic molecules (e.g., ${\mathrm{Na}}_{2}\ensuremath{\rightarrow}\mathrm{Na}+{\mathrm{Na}}^{*}$), using a combination of photoabsorption of two mutually perpendicularly polarized beams at center frequency $\ensuremath{\omega}$ and a coherent Raman transition at frequencies ${\ensuremath{\omega}}_{1}$ and ${\ensuremath{\omega}}_{2}={\ensuremath{\omega}}_{1}\ensuremath{-}\ensuremath{\omega}$, one can craft entangled states composed of arbitrary superpositions of sequences of atomic states, such as $|f\ensuremath{\rangle}|f\ensuremath{\rangle}|b\ensuremath{\rangle}+\ensuremath{\cdots}+|b\ensuremath{\rangle}|b\ensuremath{\rangle}|f\ensuremath{\rangle}+\ensuremath{\cdots},$ where $|f\ensuremath{\rangle}$ designates a dissociation process in which the ground-state Na atom goes in the forwarddirection and the excited-state Na${}^{*}$ goes in the backward direction, while $|b\ensuremath{\rangle}$ designates the reverse process, namely, Na going in the backward direction and Na${}^{*}$ going in the forward direction. The method, which on the basis of past work is expected to be robust against decoherence, would enable the encoding of very long sequences of entangled qubits.

Coherently driven quantum features using a linear optics-based polarization-basis control

Byoung Seung HAM

Quantum entanglement generation is generally known to be impossible by any classical means. According to Poisson statistics, coherent photons are not considered quantum particles due to the bunching phenomenon. Recently, a coherence approach has been applied for quantum correlations such as the Hong-Ou-Mandel (HOM) effect, Franson-type nonlocal correlation, and delayed-choice quantum eraser to understand the mysterious quantum features. In the coherence approach, the quantum correlation has been now understood as a direct result of selective measurements between product bases of phase-coherent photons. Especially in the HOM interpretation, it has been understood that a fixed sum-phase relation between paired photons is the bedrock of quantum entanglement. Here, a coherently excited HOM model is proposed, analyzed, and discussed for the fundamental physics of two-photon correlation using linear optics-based polarization-basis control. For this, polarization-frequency correlation in a Mach-Zehnder interferometer is coherently excited using synchronized acousto-optic modulators, where polarization-basis control is conducted via a selective measurement process of the heterodyne signals. Like quantum operator-based destructive interference in the HOM theory, a perfectly coherent analysis shows the same HOM effects of the paired coherent photons on a beam splitter, whereas individual output intensities are uniform.
