Observing a discrete time crystal on a trapped-ion qudit quantum processor
Gonzalo Camacho, Claire L. Edmunds, Michael Meth +2
Time crystals have been observed in various qubit-based quantum platforms. However, the realization of time-crystal behavior beyond period doubling has remained fairly unexplored,…
Hamiltonian simulation with explicit formulas for Digital-Analog Quantum Computing
Mikel Garcia-de-Andoin, Thorge Müller, Gonzalo Camacho
Digital-analog is a quantum computational paradigm that employs the natural interaction Hamiltonian of a system as the entangling resource, combined with single qubit gates, to imp…
Time Crystals on Quantum Devices
Gonzalo Camacho, Benedikt Fauseweh
Time crystals are nonequilibrium phases of matter characterized by the emergence of temporal ordering, in which an interacting many-body system develops robust structure in its tim…
Critical Scaling of the Quantum Wasserstein Distance
Gonzalo Camacho, Benedikt Fauseweh
Distinguishing quantum states with minimal sampling overhead is of fundamental importance to teach quantum data to an algorithm. Recently, the quantum Wasserstein distance emerged…
Nonexistence of maximally entangled mixed states for a fixed spectrum
Gonzalo Camacho, Julio I. de Vicente
The existence of a maximally entangled pure state is a cornerstone result of entanglement theory that has paramount consequences in quantum information theory. A natural generaliza…
Quantum walk on a square lattice with identical particles
Gonzalo Camacho, Jasmin Meinecke, Janik Wolters
We investigate quantum superposition effects in two-dimensional quantum walks of identical particles with different statistics under particle exchange, starting from various differ…
