Metriq: A Collaborative Platform for Benchmarking Quantum Computers
Alessandro Cosentino, Changhao Li, Vincent Russo +6
The fragmented landscape of quantum computer benchmarks, characterized by system-specific tools and inconsistent evaluation methodologies, hinders reliable cross-platform performan…
Limitations on separable measurements by convex optimization
Somshubhro Bandyopadhyay, Alessandro Cosentino, Nathaniel Johnston +3
We prove limitations on LOCC and separable measurements in bipartite state discrimination problems using techniques from convex optimization. Specific results that we prove include…
Small sets of locally indistinguishable orthogonal maximally entangled states
Alessandro Cosentino, Vincent Russo
We study the problem of distinguishing quantum states using local operations and classical communication (LOCC). A question of fundamental interest is whether there exist sets of $…
Dequantizing read-once quantum formulas
Alessandro Cosentino, Robin Kothari, Adam Paetznick
Quantum formulas, defined by Yao [FOCS '93], are the quantum analogs of classical formulas, i.e., classical circuits in which all gates have fanout one. We show that any read-once…
PPT-indistinguishable states via semidefinite programming
Alessandro Cosentino
We show a simple semidefinite program whose optimal value is equal to the maximum probability of perfectly distinguishing orthogonal maximally entangled states using any PPT measur…
Weight of quadratic forms and graph states
Alessandro Cosentino, Simone Severini
We prove a connection between Schmidt-rank and weight of quadratic forms. This provides a new tool for the classification of graph states based on entanglement. Our main tool arise…
