Noise-induced shallow circuits and absence of barren plateaus
Antonio Anna Mele, Armando Angrisani, Soumik Ghosh +4
Motivated by realistic hardware considerations of the pre-fault-tolerant era, we comprehensively study the impact of uncorrected noise on quantum circuits. We first show that in th…
Experimental measurement and a physical interpretation of quantum shadow enumerators
Daniel Miller, Kyano Levi, Lukas Postler +18
Throughout its history, the theory of quantum error correction has heavily benefited from translating classical concepts into the quantum setting. In particular, classical notions…
Constant Overhead Entanglement Distillation via Scrambling
Andi Gu, Lorenzo Leone, Kenneth Goodenough +1
High-fidelity quantum entanglement enables key quantum networking capabilities such as secure communication and distributed quantum computing, but long-distance entanglement distri…
-Positive Maps: New Characterizations and a Generation Method
Frederik vom Ende, Sumeet Khatri, Sergey Denisov
We study -positive linear maps on matrix algebras and address two problems, (i) characterizations of -positivity and (ii) generation of non-decomposable -positive maps. On…
Reinforcement learning of quantum circuit architectures for molecular potential energy curves
Maureen Krumtünger, Alissa Wilms, Paul K. Faehrmann +4
Quantum chemistry and optimization are two of the most prominent applications of quantum computers. Variational quantum algorithms have been proposed for solving problems in these…
Maximum channel entropy principle and microcanonical channels
Philippe Faist, Sumeet Khatri
The thermal state plays a number of significant roles throughout physics, information theory, quantum computing, and machine learning. It arises from Jaynes' maximum-entropy princi…
