Optical modulation of coherent phonon emission in optomechanical cavities
J. Maire, G. Arregui, N. Capuj +5 more·Feb 4, 2018
Optomechanical (OM) structures are well suited to study photon-phonon interactions, and they also turn out to be potential building blocks for phononic circuits and quantum computing. In phononic circuits, in which information is carried and processe...
A tunable Josephson platform to explore many-body quantum optics in circuit-QED
Javier Puertas Martínez, S. Leger, Nicolas Gheeraert +10 more·Feb 2, 2018
The interaction between light and matter remains a central topic in modern physics despite decades of intensive research. Coupling an isolated emitter to a single mode of the electromagnetic field is now routinely achieved in the laboratory, and stan...
Accelerated Variational Quantum Eigensolver.
Daochen Wang, O. Higgott, S. Brierley·Feb 1, 2018
The problem of finding the ground state energy of a Hamiltonian using a quantum computer is currently solved using either the quantum phase estimation (QPE) or variational quantum eigensolver (VQE) algorithms. For precision ε, QPE requires O(1) repet...
A Continuous - Time Quantum Walk for Attributed Graphs Matching
Tewabe Chekole Workneh·Jan 31, 2018
Diverse facets Of the Theory of Quantum Walks on Graph are reviewed Till now .In specific, Quantum network routing, Quantum Walk Search Algorithm, Element distinctness associated to the eigenvalues of Graphs and the use of these relation /connection ...
Interacting Qubit-Photon Bound States with Superconducting Circuits
N. Sundaresan, Rex Lundgren, Guanyu Zhu +2 more·Jan 30, 2018
Qubits strongly coupled to a photonic crystal give rise to qubit-photon dressed bound states. These bound states, comprising the qubits and spatially localized photonic modes induced around the qubits, are the basis for many exotic physical scenarios...
A generalized circuit for the Hamiltonian dynamics through the truncated series
A. Daskin, S. Kais·Jan 29, 2018
In this paper, we present a method for Hamiltonian simulation in the context of eigenvalue estimation problems, which improves earlier results dealing with Hamiltonian simulation through the truncated Taylor series. In particular, we present a fixed-...
LEDAkem: a post-quantum key encapsulation mechanism based on QC-LDPC codes
M. Baldi, Alessandro Barenghi, F. Chiaraluce +2 more·Jan 26, 2018
This work presents a new code-based key encapsulation mechanism (KEM) called LEDAkem. It is built on the Niederreiter cryptosystem and relies on quasi-cyclic low-density parity-check codes as secret codes, providing high decoding speeds and compact k...
Finding Maximum Cliques on the D-Wave Quantum Annealer
Guillaume Chapuis, H. Djidjev, Georg Hahn +1 more·Jan 26, 2018
This paper assesses the performance of the D-Wave 2X (DW) quantum annealer for finding a maximum clique in a graph, one of the most fundamental and important NP-hard problems. Because the size of the largest graphs DW can directly solve is quite smal...
Variational Formulation for Wannier Functions with Entangled Band Structure
Anil Damle, A. Levitt, Lin Lin·Jan 25, 2018
Wannier functions provide a localized representation of spectral subspaces of periodic Hamiltonians, and play an important role for interpreting and accelerating Hartree-Fock and Kohn-Sham density functional theory calculations in quantum physics and...
Synthetic spin–orbit coupling and topological polaritons in Janeys–Cummings lattices
F. Gu, Jia Liu, F. Mei +3 more·Jan 25, 2018
The interaction between a photon and a qubit in the Janeys–Cummings (JC) model generates a kind of quasiparticle called polariton. While they are widely used in quantum optics, difficulties in engineering-controllable coupling of them severely limit ...
Rapid High-fidelity Multiplexed Readout of Superconducting Qubits
J. Heinsoo, C. K. Andersen, A. Remm +8 more·Jan 24, 2018
The duration and fidelity of qubit readout is a critical factor for applications in quantum information processing as it limits the fidelity of algorithms which reuse qubits after measurement or apply feedback based on the measurement result. Here we...
Transfer-printed single photon sources coupled to wire waveguides
R. Katsumi, Y. Ota, M. Kakuda +2 more·Jan 24, 2018
Photonic integrated circuits (PICs) are attractive platforms to perform large-scale quantum information processing. While highly-functional PICs (e.g. silicon based photonic-circuits) and high-performance single photon sources (SPSs, e.g. compound-se...
The travelling salesman problem and adiabatic quantum computation: an algorithm
T. Kieu·Jan 24, 2018
An explicit algorithm for the travelling salesman problem is constructed in the framework of adiabatic quantum computation, AQC. The initial Hamiltonian for the AQC process admits canonical coherent states as the ground state, and the target Hamilton...

Marcello Benedetti, Delfina Garcia-Pintos, O. Perdomo +3 more·Jan 23, 2018
Hybrid quantum-classical algorithms provide ways to use noisy intermediate-scale quantum computers for practical applications. Expanding the portfolio of such techniques, we propose a quantum circuit learning algorithm that can be used to assist the ...
Dissipative environment may improve the quantum annealing performances of the ferromagnetic p -spin model

We investigate the quantum annealing of the ferromagnetic $p$-spin model in a dissipative environment ($p=5$ and $p=7$). This model, in the large-$p$ limit, codifies Grover's algorithm for searching in an unsorted database [L. K. Grover, Proceedings ...
