Cross-Platform Verification in Quantum Networks
Johannes Knörzer, Daniel Malz, J. Ignacio Cirac
Intermediate-scale quantum devices are becoming more reliable, and may soon be harnessed to solve useful computational tasks. At the same time, common classical methods used to ver…
Long-Range Free Fermions: Lieb-Robinson Bound, Clustering Properties, and Topological Phases
Zongping Gong, Tommaso Guaita, J. Ignacio Cirac
We consider free fermions living on lattices in arbitrary dimensions, where hopping amplitudes follow a power-law decay with respect to the distance. We focus on the regime where t…
Quantum advantage and stability to errors in analogue quantum simulators
Rahul Trivedi, Adrian Franco Rubio, J. Ignacio Cirac
Several quantum hardware platforms, while being unable to perform fully fault-tolerant quantum computation, can still be operated as analogue quantum simulators for addressing many…
Few-body analogue quantum simulation with Rydberg-dressed atoms in optical lattices
Daniel Malz, J. Ignacio Cirac
Most experiments with ultracold atoms in optical lattices have contact interactions, and therefore operate at high densities of around one atom per site to observe the effect of st…
Topological Effects in Two-Dimensional Quantum Emitter Systems
Miguel Bello, J. Ignacio Cirac
In this work we discuss particular effects that take place in systems of quantum emitters coupled to two-dimensional bosonic topological insulators. For a single emitter coupled to…
Free-fermion Page Curve: Canonical Typicality and Dynamical Emergence
Xie-Hang Yu, Zongping Gong, J. Ignacio Cirac
We provide further analytical insights into the newly established noninteracting (free-fermion) Page curve, focusing on both the kinematic and dynamical aspects. First, we unveil t…
