Revisiting wormhole energy conditions in Riemann-Cartan spacetimes and under Weyl transformations
Fayçal Hammad, Étienne Massé, Patrick Labelle
We show that the violation of the null energy condition by matter, required by traversable wormholes, can be removed in spacetimes with torsion. In addition, we show that this viol…
Self-correction in Wegner's 3D Ising lattice gauge theory
David Poulin, Roger G. Melko, Matthew B. Hastings
Motivated by the growing interest in self-correcting quantum memories, we study the feasibility of self-correction in classical lattice systems composed of bounded degrees of freed…
Quantum-Enhanced Noise Radar
C. W. Sandbo Chang, A. M. Vadiraj, J. Bourassa +2
We propose a novel protocol for quantum illumination: a quantum-enhanced noise radar. A two-mode squeezed state, which exhibits continuous-variable entanglement between so-called s…
Lightweight and Optimized Sound Source Localization and Tracking Methods for Open and Closed Microphone Array Configurations
Francois Grondin, Francois Michaud
Human-robot interaction in natural settings requires filtering out the different sources of sounds from the environment. Such ability usually involves the use of microphone arrays…
Black hole mechanics and thermodynamics in the light of Weyl transformations
Fayçal Hammad, Étienne Massé, Patrick Labelle
The fate of black hole thermodynamics under Weyl transformations is investigated by going back to the laws of black hole mechanics. It is shown that the transformed surface gravity…
Quantum Log-Approximate-Rank Conjecture is also False
Anurag Anshu, Naresh Goud Boddu, Dave Touchette
In a recent breakthrough result, Chattopadhyay, Mande and Sherif [ECCC TR18-17] showed an exponential separation between the log approximate rank and randomized communication compl…
Control and Coherence Time Enhancement of the 0- Qubit
Agustin Di Paolo, Arne L. Grimsmo, Peter Groszkowski +2
Kitaev's 0- qubit encodes quantum information in two protected, near-degenerate states of a superconducting quantum circuit. In a recent work, we have shown that the coherence t…
Quantum communication with time-bin encoded microwave photons
Philipp Kurpiers, Marek Pechal, Baptiste Royer +10
Heralding techniques are useful in quantum communication to circumvent losses without resorting to error correction schemes or quantum repeaters. Such techniques are realized, for…
Unusual rotating magnetocaloric effect in the hexagonal ErMnO3 single crystal
M. Balli, S. Jandl, P. Fournier +2
It is known that orthorhombic RMnO3 multiferroics (R = magnetic rare earth) with low symmetry exhibit a large rotating magnetocaloric effect because of their strong magnetocrystall…
Temperature-filling phase diagram of the two-dimensional Holstein model in the thermodynamic limit by self-consistent Migdal approximation
Philip M. Dee, Ken Nakatsukasa, Yan Wang +1
We study the temperature-filling phase diagram of the single-band Holstein model in two dimensions using the self-consistent Migdal approximation, where both the electron and phono…
Influence of Landau levels in the phonon dispersion of Weyl semimetals
Pierre Rinkel, Pedro L. S. Lopes, Ion Garate
Weyl semimetals display unusual electronic transport properties when placed under magnetic fields. Here, we investigate how magnetic fields alter the dynamics of long wavelength la…
Coexistence of Superconductivity and Antiferromagnetism in the Hubbard model for cuprates
A. Foley, S. Verret, A. -M. S. Tremblay +1
Antiferromagnetism and -wave superconductivity are the most important competing ground-state phases of cuprate superconductors. Using cellular dynamical mean-field theory (CDMFT…
Observing the post-merger signal of GW170817-like events with improved gravitational-wave detectors
Andoni Torres-Rivas, Katerina Chatziioannou, Andreas Bauswein +1
The recent detection of a neutron star binary through gravitational waves, GW170817, has offered another source of information about the properties of cold supranuclear matter. Inf…
Towards low overhead magic state distillation
Anirudh Krishna, Jean-Pierre Tillich
Magic state distillation is a resource intensive sub-routine for quantum computation. The ratio of noisy input states to output states with error rate at most scales as $O(\log…
Neural Belief-Propagation Decoders for Quantum Error-Correcting Codes
Ye-Hua Liu, David Poulin
Belief-propagation (BP) decoders play a vital role in modern coding theory, but they are not suitable to decode quantum error-correcting codes because of a unique quantum feature c…
The Generic SysML/KAOS Domain Metamodel
Steve Jeffrey Tueno Fotso, Marc Frappier, Régine Laleau +2
This paper is related to the generalised/generic version of the SysML/KAOS domain metamodel and on translation and back propagation rules between the new domain models and B System…
Magic state distillation with punctured polar codes
Anirudh Krishna, Jean-Pierre Tillich
We present a scheme for magic state distillation using punctured polar codes. Our results build on some recent work by Bardet et al. (ISIT, 2016) who discovered that polar codes ca…
Decoding Schemes for Foliated Sparse Quantum Error Correcting Codes
A. Bolt, D. Poulin, T. M. Stace
Foliated quantum codes are a resource for fault-tolerant measurement-based quantum error correction for quantum repeaters and for quantum computation. They represent a general appr…
Concavity, Response Functions and Replica Energy
Alessandro Campa, Lapo Casetti, Ivan Latella +2
In nonadditive systems, like small systems or like long-range interacting systems even in the thermodynamic limit, ensemble inequivalence can be related to the occurrence of negati…
Transport signatures of surface states in a Weyl semimetal: evidence of field driven Fermi arc interferometry
Nityan L. Nair, Marie-Eve Boulanger, Francis Laliberté +8
A signature property of Weyl semimetals is the existence of topologically protected surface states - arcs in momentum space that connect Weyl points in the bulk. However, the prese…
Probing the role of Nd3+ ions in the weak multiferroic character of NdMn2O5 by optical spectroscopies
S. Mansouri, S. Jandl, M. Balli +6
Raman and infrared spectroscopies are used as local probes to study the dynamics of the Nd-O bonds in the weakly multiferroic NdMn2O5 system. The temperature dependence of selected…
