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…
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…
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…
Sufficient condition for universal quantum computation using bosonic circuits
Cameron Calcluth, Nicolas Reichel, Alessandro Ferraro +1
Continuous-variable bosonic systems stand as prominent candidates for implementing quantum computational tasks. While various necessary criteria have been established to assess the…
The vacuum provides quantum advantage to otherwise simulatable architectures
Cameron Calcluth, Alessandro Ferraro, Giulia Ferrini
We consider a computational model composed of ideal Gottesman-Kitaev-Preskill stabilizer states, Gaussian operations - including all rational symplectic operations and all real dis…
Efficient simulation of Gottesman-Kitaev-Preskill states with Gaussian circuits
Cameron Calcluth, Alessandro Ferraro, Giulia Ferrini
We study the classical simulatability of Gottesman-Kitaev-Preskill (GKP) states in combination with arbitrary displacements, a large set of symplectic operations and homodyne measu…
Efficient simulatability of continuous-variable circuits with large Wigner negativity
Laura García-Álvarez, Cameron Calcluth, Alessandro Ferraro +1
Discriminating between quantum computing architectures that can provide quantum advantage from those that cannot is of crucial importance. From the fundamental point of view, estab…
