Quantum Machine Learning in the Cognitive Domain: Alzheimer's Disease Study
Emine Akpinar·Sep 15, 2023
Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder, primarily affecting the elderly population and leading to significant cognitive decline. This decline manifests in various mental faculties such as attention, memory, and high...
Benchmarking machine learning models for quantum state classification
Edoardo Pedicillo, Andrea Pasquale, S. Carrazza·Sep 14, 2023
Quantum computing is a growing field where the information is processed by two-levels quantum states known as qubits. Current physical realizations of qubits require a careful calibration, composed by different experiments, due to noise and decoheren...
Entanglement of Sections: The pushout of entangled and parameterized quantum information
Hisham Sati, Urs Schreiber·Sep 13, 2023
A question raised by Freedman & Hastings (2023) still stands: To produce a mathematical theory that would unify quantum entanglement/tensor-structure with parameterized/bundle-structure via their amalgamation (a hypothetical pushout) along bare quant...
Near-term distributed quantum computation using mean-field corrections and auxiliary qubits
A. Gomez, T. Patti, Anima Anandkumar +1 more·Sep 11, 2023
Distributed quantum computation is often proposed to increase the scalability of quantum hardware, as it reduces cooperative noise and requisite connectivity by sharing quantum information between distant quantum devices. However, such exchange of qu...
Detecting Violations of Differential Privacy for Quantum Algorithms
J. Guan, Wang Fang, Mingyu Huang +1 more·Sep 9, 2023
Quantum algorithms for solving a wide range of practical problems have been proposed in the last ten years, such as data search and analysis, product recommendation, and credit scoring. The concern about privacy and other ethical issues in quantum co...
Physics-informed neural networks for an optimal counterdiabatic quantum computation
Antonio Ferrer-S'anchez, Carlos Flores-Garrigos, C. Hernani-Morales +7 more·Sep 8, 2023
A novel methodology that leverages physics-informed neural networks to optimize quantum circuits in systems with NQ qubits by addressing the counterdiabatic (CD) protocol is introduced. The primary purpose is to employ physics-inspired deep learning ...
Quantum Graph-State Synthesis with SAT
Sebastiaan Brand, T. Coopmans, A. Laarman·Sep 7, 2023
In quantum computing and quantum information processing, graph states are a specific type of quantum states which are commonly used in quantum networking and quantum error correction. A recurring problem is finding a transformation from a given sourc...
Quantum Cellular Automata for Quantum Error Correction and Density Classification.
Thiago L. M. Guedes, Don Winter, Markus Muller·Sep 7, 2023
Quantum cellular automata are alternative quantum-computing paradigms to quantum Turing machines and quantum circuits. Their working mechanisms are inherently automated, therefore measurement free, and they act in a translation invariant manner on al...
Accurate hyperfine tensors for solid state quantum applications: case of the NV center in diamond
Istv'an Tak'acs, Viktor Iv'ady·Sep 7, 2023
The decoherence of point defect qubits is often governed by the electron spin-nuclear spin hyperfine interaction that can be parameterized by using ab inito calculations in principle. So far most of the theoretical works have focused on the hyperfine...
Logical states for fault-tolerant quantum computation with propagating light
Shunya Konno, W. Asavanant, F. Hanamura +14 more·Sep 5, 2023
To harness the potential of a quantum computer, quantum information must be protected against error by encoding it into a logical state that is suitable for quantum error correction. The Gottesman-Kitaev-Preskill (GKP) qubit is a promising candidate ...
Page Time as a Transition of Information Channels: High-fidelity Information Retrieval for Radiating Black Holes
Ran Li, Xuanhua Wang, Kun Zhang +1 more·Sep 5, 2023
The effective field theory description of a radiating black hole introduces redundant degrees of freedom that necessitate annihilation of those modes at late stages to conserve entropy. The prevailing view is that such effective process can result in...

Quantum information processing has witnessed significant advancements through the application of qubit-based techniques within universal gate sets. Recently, exploration beyond the qubit paradigm to $d$-dimensional quantum units or qudits has opened ...
High-Precision Observable Estimation with Single Qubit Quantum Memory
L. A. Markovich, J. Borregaard·Aug 31, 2023
The estimation of multi-qubit observables is a key task in quantum information science. The standard approach is to decompose a multi-qubit observable into a weighted sum of Pauli strings. The observable can then be estimated from projective single q...
