Efficient graph-diagonal characterization of noisy states distributed over quantum networks via Bell sampling
Zherui Jerry Wang, Joshua Carlo A. Casapao, Naphan Benchasattabuse +6
Graph states are an important class of entangled states that serve as a key resource for distributed information processing and communication in quantum networks. In this work, we…
Many-body -local ground states as probes for unitary quantum metrology
Majid Hassani, Mengyao Hu, Guillem Müller-Rigat +2
Multipartite quantum states saturating the Heisenberg limit of sensitivity typically require full-body correlators to be prepared. On the other hand, experimentally practical Hamil…
Tailoring Bell inequalities to the qudit toric code and self testing
Eloïc Vallée, Owidiusz Makuta, Patrick Emonts +2
Bell nonlocality provides a robust scalable route to the efficient certification of quantum states. Here, we introduce a general framework for constructing Bell inequalities tailor…
Measuring multipartite entanglement efficiently by testing symmetries
Xiaoyu Liu, Jordi Tura, Albert Rico
Recently, a technique known as quantum symmetry test has gained increasing attention for detecting bipartite entanglement in pure quantum states. In this work we show that, beyond…
Optimizing quantum violation yields facet Bell inequalities
Jin-Fu Chen, Mengyao Hu, Jordi Tura
Nonlocality is revealed through violations of Bell inequalities, whose complete characterization defines the local polytope. For multipartite systems, however, the local polytope b…
Nonparametric Learning Non-Gaussian Quantum States of Continuous Variable Systems
Liubov A. Markovich, Xiaoyu Liu, Jordi Tura
Continuous-variable quantum systems are foundational to quantum computation, communication, and sensing. While traditional representations using wave functions or density matrices…
Preparing low-variance states using a distributed quantum algorithm
Xiaoyu Liu, Benjamin F. Schiffer, Jordi Tura
Quantum computers are a highly promising tool for efficiently simulating quantum many-body systems. The preparation of their eigenstates is of particular interest and can be addres…
