Equivalence of continuous- and discrete-variable gate-based quantum computers with finite energy
Alex Maltesson, Ludvig Rodung, Niklas Budinger +2
Continuous systems are studied in many branches of modern physics, such as high-energy physics, cosmology, condensed matter physics, quantum chemistry, and field theories. Such sys…

Classical simulation of circuits with realistic odd-dimensional Gottesman-Kitaev-Preskill states
Cameron Calcluth, Oliver Hahn, Juani Bermejo-Vega +2
Classically simulating circuits with bosonic codes is challenging due to the prohibitive cost of simulating quantum systems with many, possibly infinite, energy levels. We propose…

From simulatability to universality of continuous-variable quantum computers
Cameron Calcluth
(Abridged.) Quantum computers promise to solve some problems exponentially faster than traditional computers, but we still do not fully understand why this is the case. While the m…
