Short random circuits define good quantum error correcting codes
Winton Brown, Omar Fawzi
We study the encoding complexity for quantum error correcting codes with large rate and distance. We prove that random Clifford circuits with gates can be used to e…
Foliations of Minkowski spacetime by crooked planes
Virginie Charette, Youngju Kim
Given a regular curve in Minkowski spacetime, we describe necessary and sufficient conditions for this curve to admit a family of pairwise-disjoint crooked planes. Using this crite…
Phase diagram and Fermi-liquid properties of the extended Hubbard model on the honeycomb lattice
Wei Wu, A. -M. -S. Tremblay
The Hubbard model and extended Hubbard model on the honeycomb lattice can be seen as prototype models of single layer graphene placed in a high dielectric constant environment that…
Long-range spin transfer in triple quantum dots
R. Sánchez, G. Granger, L. Gaudreau +6
Tunneling in a quantum coherent structure is not restricted to only nearest neighbours. Hopping between distant sites is possible via the virtual occupation of otherwise avoided in…
Tensor Networks and Quantum Error Correction
Andrew J. Ferris, David Poulin
We establish several relations between quantum error correction (QEC) and tensor network (TN) methods of quantum many-body physics. We exhibit correspondences between well-known fa…
Charge, spin and lattice effects in the spin-Peierls ground state of MEM(TCNQ)
M. Poirier, M. de Lafontaine, C. Bourbonnais +1
We report an investigation of charge, spin and lattice effects in the spin-Peierls state of the organic compound MEM(TCNQ). The 16.5 GHz dielectric function along the chain axi…
Thermalization, Error-Correction, and Memory Lifetime for Ising Anyon Systems
Courtney G. Brell, Simon Burton, Guillaume Dauphinais +2
We consider two-dimensional lattice models that support Ising anyonic excitations and are coupled to a thermal bath. We propose a phenomenological model for the resulting short-tim…
Validity of the two-band model of bilayer and trilayer graphene in a magnetic field
R. Côté, Manuel Barrette
The eigenstates of an electron in the chiral two-dimensional electron gas (C2DEG) formed in an AB-stacked bilayer or an ABC-stacked trilayer graphene is a spinor with or co…
Recollision scenario without tunneling : Role of the ionic core potential
Adam Kamor, Cristel Chandre, Turgay Uzer +1
The standard model of strong laser physics, the recollision scenario, omits the ionic core potential after tunneling. Strikingly, although the Coulomb interaction drives all stages…
Bipolar spin blockade and coherent state superpositions in a triple quantum dot
M. Busl, G. Granger, L. Gaudreau +8
Spin qubits based on interacting spins in double quantum dots have been successfully demonstrated. Readout of the qubit state involves a conversion of spin to charge information, u…
Hardness of decoding quantum stabilizer codes
Pavithran Iyer, David Poulin
In this article we address the computational hardness of optimally decoding a quantum stabilizer code. Much like classical linear codes, errors are detected by measuring certain ch…
Reducing complexes in multidimensional persistent homology theory
Madjid Allili, Tomasz Kaczynski, Claudia Landi
The Discrete Morse Theory of Forman appeared to be useful for providing filtration-preserving reductions of complexes in the study of persistent homology. So far, the algorithms co…
Fourier transform of fermionic systems and the spectral tensor network
Andrew J. Ferris
Leveraging the decomposability of the fast Fourier transform, I propose a new class of tensor network that is efficiently contractible and able to represent many-body systems with…
A Deep and Tractable Density Estimator
Benigno Uria, Iain Murray, Hugo Larochelle
The Neural Autoregressive Distribution Estimator (NADE) and its real-valued version RNADE are competitive density models of multidimensional data across a variety of domains. These…
Wiedemann-Franz law and non-vanishing temperature scale across the field-tuned quantum critical point of YbRh2Si2

The in-plane thermal conductivity kappa(T) and electrical resistivity rho(T) of the heavy-fermion metal YbRh2Si2 were measured down to 50 mK for magnetic fields H parallel and perp…
Superconducting qubit as a probe of quantum fluctuations in a nonlinear resonator
Maxime Boissonneault, A. C. Doherty, F. R. Ong +4
In addition to their central role in quantum information processing, qubits have proven to be useful tools in a range of other applications such as enhanced quantum sensing and as…
Re-entrant magnetic field induced charge and spin gaps in the coupled dual-chain quasi-one dimensional organic conductor Perylene[Pt(mnt)]
L. E. Winter, J. S. Brooks, P. Schlottmann +3
An inductive method is used to follow the magnetic field-dependent susceptibility of the coupled charge density wave (CDW) and spin-Peierls (SP) ordered state behavior in the dual…
Possible charge analogues of spin transfer torques in bulk superconductors
Ion Garate
Spin transfer torques (STT) occur when electric currents travel through inhomogeneously magnetized systems and are important for the motion of magnetic textures such as domain wall…
Evidence from Tunneling Spectroscopy for a Quasi-One Dimensional Origin of Superconductivity in Sr2RuO4
I. A. Firmo, S. Lederer, C. Lupien +3
To establish the mechanism of unconventional superconductivity in SrRUO, a prerequisite is direct information concerning the momentum-space structure of the energy gaps $Δ_…
