Quantifying fault tolerant simulation of strongly correlated systems using the Fermi-Hubbard model
Anjali A. Agrawal, Joshua Job, Tyler L. Wilson +8
Understanding the physics of strongly correlated materials is one of the grand challenge problems for physics today. A large class of scientifically interesting materials, from hig…
Superconducting qubits in the millions: the potential and limitations of modularity
S. N. Saadatmand, Tyler L. Wilson, Mark J. Hodson +11
The development of fault-tolerant quantum computers (FTQCs) is receiving increasing attention within the quantum computing community. Like conventional digital computers, FTQCs, wh…
Optimized Laser Models with Heisenberg-Limited Coherence and Sub-Poissonian Beam Photon Statistics
L. A. Ostrowski, T. J. Baker, S. N. Saadatmand +1
Recently it has been shown that it is possible for a laser to produce a stationary beam with a coherence (quantified as the mean photon number at spectral peak) which scales as the…
No Tradeoff between Coherence and Sub-Poissonianity for Heisenberg-Limited Lasers
L. A. Ostrowski, T. J. Baker, S. N. Saadatmand +1
The Heisenberg limit to laser coherence -- the number of photons in the maximally populated mode of the laser beam -- is the fourth power of the number of excitation…
The Heisenberg limit for laser coherence
Travis J. Baker, S. N. Saadatmand, Dominic W. Berry +1
To quantify quantum optical coherence requires both the particle- and wave-natures of light. For an ideal laser beam [1,2,3], it can be thought of roughly as the number of photons…
Thermodynamics from first principles: correlations and nonextensivity
S. N. Saadatmand, Tim Gould, E. G. Cavalcanti +1
The standard formulation of thermostatistics, being based on the Boltzmann-Gibbs distribution and logarithmic Shannon entropy, describes idealized uncorrelated systems with extensi…
Phase diagram of the quantum Ising model with long-range interactions on an infinite-cylinder triangular lattice
S. N. Saadatmand, S. D. Bartlett, I. P. McCulloch
Obtaining quantitative ground-state behavior for geometrically-frustrated quantum magnets with long-range interactions is challenging for numerical methods. Here, we demonstrate th…
Detection and characterization of symmetry-broken long-range orders in the spin- triangular Heisenberg model
S. N. Saadatmand, I. P. McCulloch
We present new numerical tools to analyze symmetry-broken phases in the context of -symmetric translation-invariant matrix product states (MPS) and density-matrix renormaliz…
Symmetry fractionalization in the topological phase of the spin- - triangular Heisenberg model
S. N. Saadatmand, I. P. McCulloch
Using density-matrix renormalization-group calculations for infinite cylinders, we elucidate the properties of the spin-liquid phase of the spin- - Heisenber…
Phase Diagram of the Spin- Triangular - Heisenberg Model on a 3-leg Cylinder
S. N. Saadatmand, B. J. Powell, I. P. McCulloch
We study the phase diagram of the frustrated Heisenberg model on the triangular lattice with nearest and next-nearest neighbor spin exchange coupling, on 3-leg ladders. Using the d…
