Warm-Starting and Quantum Computing: A Systematic Mapping Study
Felix Truger, Johanna Barzen, Marvin Bechtold +4 more·Mar 10, 2023
Due to low numbers of qubits and their error-proneness, Noisy Intermediate-Scale Quantum (NISQ) computers impose constraints on the size of quantum algorithms they can successfully execute. State-of-the-art research introduces various techniques addr...
Variational Quantum Neural Networks (VQNNS) in Image Classification
Meghashrita Das, T. Bolisetti·Mar 10, 2023
Quantum machine learning has established as an interdisciplinary field to overcome limitations of classical machine learning and neural networks. This is a field of research which can prove that quantum computers are able to solve problems with compl...
Simulating non-unitary dynamics using quantum signal processing with unitary block encoding
H. Chan, D. M. Ramo, Nathan Fitzpatrick·Mar 10, 2023
We adapt a recent advance in resource-frugal quantum signal processing - the Quantum Eigenvalue Transform with Unitary matrices (QET-U) - to explore non-unitary imaginary time evolution on early fault-tolerant quantum computers using exactly emulated...
Adaptive quantum error mitigation using pulse-based inverse evolutions
Ivan Henao, Jader P. Santos, R. Uzdin·Mar 9, 2023
Quantum Error Mitigation (QEM) enables the extraction of high-quality results from the presently-available noisy quantum computers. In this approach, the effect of the noise on observables of interest can be mitigated using multiple measurements with...
Efficient and Error-Resilient Data Access Protocols for a Limited-Sized Quantum Random Access Memory
Zhao-Yun Chen, Cheng Xue, Yun-Jie Wang +8 more·Mar 9, 2023
Quantum Random Access Memory (QRAM) is a critical component for loading classical data into quantum computers. While constructing a practical QRAM presents several challenges, including the impracticality of an infinitely large QRAM size and a fully ...
Adiabatic elimination for composite open quantum systems: Reduced-model formulation and numerical simulations
François-Marie Le Régent, Pierre Rouchon·Mar 9, 2023
A numerical method is proposed for simulation of composite open quantum systems. It is based on Lindblad master equations and adiabatic elimination. Each subsystem is assumed to converge exponentially towards a stationary subspace, slightly impacted ...
Quantum memory error correction computation based on Chamon model
Jian Zhao, Yuchun Wu, Guo‐Ping Guo·Mar 9, 2023
Quantum error correction codes play a central role in the realisation of fault-tolerant quantum computing. Chamon model is a 3D generalization of the toric code. The error correction computation on this model has not been explored so far. In this wor...
Optimizing quantum noise-induced reservoir computing for nonlinear and chaotic time series prediction
D. Fry, Amol Deshmukh, Samuel Yen-Chi Chen +2 more·Mar 9, 2023
Quantum reservoir computing is strongly emerging for sequential and time series data prediction in quantum machine learning. We make advancements to the quantum noise-induced reservoir, in which reservoir noise is used as a resource to generate expre...
Quantum Magic via Perfect Pauli Sampling of Matrix Product States
Guglielmo Lami, M. Collura·Mar 9, 2023
We introduce a novel breakthrough approach to evaluate the nonstabilizerness of an $N$-qubits Matrix Product State (MPS) with bond dimension $\chi$. In particular, we consider the recently introduced Stabilizer R\'enyi Entropies (SREs). We show that ...
Absorbing state phase transition with Clifford circuits
Nastasia Makki, Nicolai Lang, H. Büchler·Mar 9, 2023
The role of quantum fluctuations in modifying the critical behavior of non-equilibrium phase transitions is a fundamental but unsolved question. In this study, we examine the absorbing state phase transition of a 1D chain of qubits undergoing a conta...
Harnessing Quantumness of States using Discrete Wigner Functions under (non)‐Markovian Quantum Channels
Jai Lalita, K. G. Paulson, Subhashis Banerjee·Mar 9, 2023
The negativity of the discrete Wigner functions (DWFs) is a measure of non‐classicality and is often used to quantify the degree of quantum coherence in a system. The study of Wigner negativity and its evolution under different quantum channels can p...
Quantum-enhanced greedy combinatorial optimization solver
M. Dupont, B. Evert, Mark Hodson +13 more·Mar 9, 2023
Combinatorial optimization is a broadly attractive area for potential quantum advantage, but no quantum algorithm has yet made the leap. Noise in quantum hardware remains a challenge, and more sophisticated quantum-classical algorithms are required t...
