Relaxation to Negative Temperatures in Double Domain Systems
Yusuke Hama, William J. Munro, Kae Nemoto
We investigate the relaxation of two collective spins in double domain system, which are individually coupled to a single bosonic reservoir, by varying the total number of spins in…
A Characterization of Constant-Sample Testable Properties
Eric Blais, Yuichi Yoshida
We characterize the set of properties of Boolean-valued functions on a finite domain that are testable with a constant number of samples. Specifically, we show that a…
Steady-state generation of negative-Wigner-function light using feedback
Cristian Joana, Peter van Loock, Hui Deng +1
We propose a method of producing steady-state coherent light with negative Wigner functions in nonlinear media combined with feedback control. While the nonlinearities are essentia…
Bayesian Body Schema Estimation using Tactile Information obtained through Coordinated Random Movements
Tomohiro Mimura, Yoshinobu Hagiwara, Tadahiro Taniguchi +1
This paper describes a computational model, called the Dirichlet process Gaussian mixture model with latent joints (DPGMM-LJ), that can find latent tree structure embedded in data…
Projective measurement of energy on an ensemble of qubits with unknown frequencies
Yuichiro Matsuzaki, Shojun Nakayama, Akihito Soeda +2
In projective measurements of energy, a target system is projected to an eigenstate of the system Hamiltonian, and the measurement outcomes provide the information of corresponding…
Repeaters for Continuous Variable Quantum Communication
Fabian Furrer, William J. Munro
Optical telecommunication is at the heart of today's internet and is currently enabled by the transmission of intense optical signals between remote locations. As we look to the fu…
Energy landscape analysis of neuroimaging data
Takahiro Ezaki, Takamitsu Watanabe, Masayuki Ohzeki +1
Computational neuroscience models have been used for understanding neural dynamics in the brain and how they may be altered when physiological or other conditions change. We review…
Learning to Navigate in Complex Environments
Piotr Mirowski, Razvan Pascanu, Fabio Viola +9
Learning to navigate in complex environments with dynamic elements is an important milestone in developing AI agents. In this work we formulate the navigation question as a reinfor…
Graph spectral characterisation of the XY model on complex networks
Paul Expert, Sarah de Nigris, Taro Takaguchi +1
There is recent evidence that the spin model on complex networks can display three different macroscopic states in response to the topology of the network underpinning the int…
Product states and Schmidt rank of mutually unbiased bases in dimension six
Lin Chen, Li Yu
We show that if a set of four mutually unbiased bases (MUBs) in exists and contains the identity, then any other basis in the set contains at most two product states…
Correlation based entanglement criteria for bipartite systems
Yumang Jing, Qiongyi He, Tim Byrnes
We introduce a class of inequalities based on low order correlations of operators to detect entanglement in bipartite systems. The operators may either be Hermitian or non-Hermitia…
A tight analysis of Kierstead-Trotter algorithm for online unit interval coloring
Tetsuya Araki, Koji M. Kobayashi
Kierstead and Trotter (Congressus Numerantium 33, 1981) proved that their algorithm is an optimal online algorithm for the online interval coloring problem. In this paper, for onli…
Ultrafast coherent control of spinor Bose-Einstein condensates using stimulated Raman adiabatic passage
Andreas Thomasen, Tetsuya Mukai, Tim Byrnes
We propose the use of stimulated Raman adiabatic passage (STIRAP) to offer a fast high fidelity method of performing SU(2) rotations on spinor Bose Einstein condensates (BEC). Past…
Physical Layer Security-Aware Routing and Performance Tradeoffs in Ad Hoc Networks
Yang Xu, Jia Liu, Yulong Shen +2
The application of physical layer security in ad hoc networks has attracted considerable academic attention recently. However, the available studies mainly focus on the single-hop…
On Performance Modeling for MANETs under General Limited Buffer Constraint
Jia Liu, Yang Xu, Yulong Shen +2
Understanding the real achievable performance of mobile ad hoc networks (MANETs) under practical network constraints is of great importance for their applications in future highly…
Quantum feedback control of atomic ensembles and spinor Bose-Einstein condensates
Shi Wang, Tim Byrnes
Cold atomic ensembles and spinor Bose-Einstein condensates (BECs) are potential candidates for quantum memories as they have long coherence times and can be coherently controlled.…
Minimizing Quadratic Functions in Constant Time
Kohei Hayashi, Yuichi Yoshida
A sampling-based optimization method for quadratic functions is proposed. Our method approximately solves the following -dimensional quadratic minimization problem in constant t…
Testing Assignments to Constraint Satisfaction Problems
Hubie Chen, Matt Valeriote, Yuichi Yoshida
For a finite relational structure A, let CSP(A) denote the CSP instances whose constraint relations are taken from A. The resulting family of problems CSP(A) has been considered he…
Quantum metrology including state preparation and readout times
Shane Dooley, William J. Munro, Kae Nemoto
There is growing belief that the next decade will see the emergence of sensing devices based on the laws of quantum physics that outperform some of our current sensing devices. For…
Random Walk Graph Laplacian based Smoothness Prior for Soft Decoding of JPEG Images
Xianming Liu, Gene Cheung, Xiaolin Wu +1
Given the prevalence of JPEG compressed images, optimizing image reconstruction from the compressed format remains an important problem. Instead of simply reconstructing a pixel bl…
The Birkhoff theorem for unitary matrices of arbitrary dimensions
Stijn De Baerdemacker, Alexis De Vos, Lin Chen +1
It was shown recently that Birkhoff's theorem for doubly stochastic matrices can be extended to unitary matrices with equal line sums whenever the dimension of the matrices is prim…

Ebubechukwu O. Ilo-Okeke, Tim Byrnes
We further examine a theory of phase contrast imaging (PCI) of cold atomic gases, first introduced by us in Phys. Rev. Lett. {\bf 112}, 233602 (2014). We model the PCI measurement…
