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…
Squeezing light to get nonclassical work in quantum engines
A. Tejero, D. Manzano, P. I. Hurtado
Light can be squeezed by reducing the quantum uncertainty of the electric field for some phases. We show how to use this purely quantum effect to extract net mechanical work from r…
Reducing depth and measurement weights in Pauli-based computation
Filipa C. R. Peres, Ernesto F. Galvão
Pauli-based computation (PBC) is a universal measurement-based quantum computation model steered by an adaptive sequence of independent and compatible Pauli measurements on separab…
Reduction of unitary operators, quantum graphs and quantum channels
L. L. Salcedo
Given a unitary operator in a finite dimensional complex Hilbert space, its unitary reduction to a subspace is defined. The application to quantum graphs is discussed. It is shown…
Asymmetries of thermal processes in open quantum systems
Álvaro Tejero, Rafael Sánchez, Laiachi El Kaoutit +2
An intriguing phenomenon in non-equilibrium quantum thermodynamics is the asymmetry of thermal processes. Relaxation to thermal equilibrium is the most important dissipative proces…
Certifying nonstabilizerness in quantum processors
Rafael Wagner, Filipa C. R. Peres, Emmanuel Zambrini Cruzeiro +1
Nonstabilizerness, also known as magic, is a crucial resource for quantum computation. The growth in complexity of quantum processing units (QPUs) demands robust and scalable techn…
