Inferring charge-noise source locations from correlations in spin qubits
Juan S. Rojas-Arias, Akito Noiri, Jun Yoneda +7 more·May 9, 2025
We investigate low-frequency noise in a spin-qubit device made in isotopically purified Si/Si-Ge. Observing sizable cross-correlations among energy fluctuations of different qubits, we conclude that these fluctuations are dominated by charge noise. A...

Byungmin Kang, Chen Zhao, Zhengwei Liu +2 more·May 9, 2025
Simulating generic quantum states and dynamics is practically intractable using classical computers. However, certain special classes -- namely Clifford and matchgate circuits -- permit efficient computation. They provide invaluable tools for studyin...
Quantum medical image encoding and compression using Fourier-based methods
Taehee Ko, Inho Lee, H. Yu·May 9, 2025
Quantum image processing (QIMP) has recently emerged as a promising field for modern image processing applications. In QIMP algorithms, encoding classical image informaiton into quantum circuit is important as the first step. However, most of existin...
From Fermions to Qubits: A ZX-Calculus Perspective
Haytham McDowall-Rose, R. A. Shaikh, L. Yeh·May 9, 2025
Mapping fermionic systems to qubits on a quantum computer is often the first step for algorithms in quantum chemistry and condensed matter physics. However, it is difficult to reconcile the many different approaches that have been proposed, such as t...
Landauer principle and thermodynamics of computation
Pritam Chattopadhyay, A. Misra, Tanmoy Pandit +1 more·May 9, 2025
According to the Landauer principle, any logically irreversible process accompanies entropy production, which results in heat dissipation in the environment. Erasing of information, one of the primary logically irreversible processes, has a lower bou...
Optimization of Quantum Error Correcting Code under Temporal Variation of Qubit Quality
Subrata Das, Swaroop Ghosh·May 9, 2025
Error rates in current noisy quantum hardware are not static; they vary over time and across qubits. This temporal and spatial variation challenges the effectiveness of fixed-distance quantum error correction (QEC) codes. In this paper, we analyze 12...
