Superradiance in spin- particles: Effects of multiple levels

G. -D. Lin, S. F. Yelin

We study the superradiance dynamics in a dense system of atoms each of which can be generally a spin- particle with an arbitrary half-integer. We generalize Dicke's superrad…

Topologically Protected Quantum State Transfer in a Chiral Spin Liquid

Norman Y. Yao, Chris R. Laumann, Alexey V. Gorshkov +5

Topology plays a central role in ensuring the robustness of a wide variety of physical phenomena. Notable examples range from the robust current carrying edge states associated wit…

Long-range quantum gates using dipolar crystals

Hendrik Weimer, Norman Y. Yao, Chris R. Laumann +1

We propose the use of dipolar spin chains to enable long-range quantum logic between distant qubits. In our approach, an effective interaction between remote qubits is achieved by…

New Quantum Bounds for Inequalities involving Marginal Expectations

Elie Wolfe, S. F. Yelin

We review, correct, and develop an algorithm which determines arbitrary Quantum Bounds, based on the seminal work of Tsirelson [Lett. Math. Phys. 4, 93 (1980)]. The potential of th…

A microscopic model of electronic field noise heating in ion traps

A. Safavi-Naini, P. Rabl, P. Weck +1

Motional heating of ions in micro-fabricated traps is a challenge hindering experimental realization of large-scale quantum processing devices. Recently a series of measurements of…

Cluster state generation using van der Waals and dipole-dipole interactions in optical lattices

Elena Kuznetsova, T. Bragdon, Robin Côté +1

We present a scalable method for generation of a cluster state for measurement-based quantum computing using van der Waals or dipole-dipole interactions between neutral atoms or po…

Rydberg atom mediated polar molecule interactions: a tool for molecular-state conditional quantum gates and individual addressability

Elena Kuznetsova, Seth T. Rittenhouse, Hossein R. Sadeghpour +1

We study the possibility to use interaction between a polar molecule in the ground electronic and vibrational state and a Rydberg atom to construct two-qubit gates between molecula…

Probabilistic Generation of Quantum Contextual Sets

Norman D. Megill, Kresimir Fresl, Mordecai Waegell +2

We give a method for exhaustive generation of a huge number of Kochen-Specker contextual sets, based on the 600-cell, for possible experiments and quantum gates. The method is comp…

Attosecond two-photon interferometry for doubly excited states of helium

J. Feist, S. Nagele, C. Ticknor +3

We show that the correlation dynamics in coherently excited doubly excited resonances of helium can be followed in real time by two-photon interferometry. This approach promises to…

Digital Quantum Simulation with Rydberg Atoms

H. Weimer, M. Müller, H. P. Büchler +1

We discuss in detail the implementation of an open-system quantum simulator with Rydberg states of neutral atoms held in an optical lattice. Our scheme allows one to realize both c…

Artificial atoms can do more than atoms: Deterministic single photon subtraction from arbitrary light fields

Jens Honer, Robert Löw, Hendrik Weimer +2

We study the interplay of photons interacting with an artificial atom in the presence of a controlled dephasing. Such artifical atoms consisting of several independent scatterer ca…

Ion crystal transducer for strong coupling between single ions and single photons

L. Lamata, D. R. Leibrandt, I. L. Chuang +4

A new approach for realization of a quantum interface between single photons and single ions in an ion crystal is proposed and analyzed. In our approach the coupling between a sing…
