Learning to Prepare Molecular Ground States with Transformer Models
Alex Koziell-Pipe, Jasmine Brewer, Jem Guhit +14
Quantum state preparation is a key component of many quantum algorithms. Performing this step efficiently is essential for realizing practical quantum advantage in quantum chemistr…
Split-Evolution Quantum Phase Estimation for Particle-Conserving Hamiltonians
Megan Cerys Rowe, Carlo A. Gaggioli, Ludmila Szulakowska +2
We present a hardware demonstration and resource analysis of split-evolution quantum phase estimation (SE-QPE) on a Quantinuum System Model H2 quantum computer. SE-QPE is a modific…
Magnetoexcitons and Massive Dirac Fermions in Monolayers of Transition Metal Dichalcogenides in a High Magnetic Field
Katarzyna Sadecka, Marek Korkusinski, Ludmiła Szulakowska +1
We present a theory of the emission spectrum of magnetoexcitons interacting with a quantum Hall state of massive Dirac fermions in monolayer transition metal dichalcogenides…
Theory of excitonic complexes in gated WSe quantum dots
Daniel Miravet, Ludmiła Szulakowska, Maciej Bieniek +2
Single-layer quantum dot gate potential causes type-II band alignment, i.e. electrostatically confines holes and repels electrons, or vice versa. Hence, the confinement of excitons…
Bayesian autotuning of Hubbard model quantum simulators
Ludmila Szulakowska, Jun Dai
Spins in gated semiconductor quantum dots (QDs) are a promising platform for Hubbard model simulation inaccessible to computation. Precise control of the tunnel couplings by tuning…
Physics graduate student employment: what we can learn from professional social media
Erin M. Tonita, Ludmila Szulakowska, Joshua Baxter +3
In this study, we investigated the employment status of recent University of Ottawa physics MSc and PhD graduates, finding that 94% of graduates are either employed or pursuing fur…
Valley and spin polarized broken symmetry states of interacting electrons in gated MoS quantum dots
Ludmila Szulakowska, Moritz Cygorek, Maciej Bieniek +1
Understanding strongly interacting electrons enables the design of materials, nanostructures and devices. Developing this understanding relies on the ability to tune and control el…
Band nesting and exciton spectrum in monolayer MoS
Maciej Bieniek, Ludmiła Szulakowska, Paweł Hawrylak
We discuss here the effect of band nesting and topology on the spectrum of excitons in a single layer of MoS, a prototype transition metal dichalcogenide material. We solve for…
The effect of valley, spin and band nesting on the electronic properties of gated quantum dots in a single layer of transition metal dichalcogenides (TMDCs)
Maciej Bieniek, Ludmila Szulakowska, Pawel Hawrylak
We present here results of atomistic theory of electrons confined by metallic gates in a single layer of transition metal dichalcogenides. The electronic states are described by th…
Electronic structure, magnetoexcitons and valley polarized electron gas in 2D crystals
Ludmila Szulakowska, Maciej Bieniek, Pawel Hawrylak
We describe here recent work on the electronic properties, magnetoexcitons and valley polarised electron gas in 2D crystals. Among 2D crystals, monolayer has attracted sign…
