Abstract: Fault-tolerance using constant space-overhead against long-range correlated errors is an important practical question. In the pioneering works [Terhal and Burkard, PRA 2005], [Aliferis et al, PRA 2005], [Aharonov et al, PRL 2006], fault-tolerance using poly-logarithmic overhead against long-range correlation modeled by pairwise joint Hamiltonian was proven when the total correlation of an error at a qubit location with errors at other locations was $O(1)$, i.e., the total correlation at a location did not scale with the number of qubits. This condition, under spatial symmetry, can simply be stated as the correlation between locations decaying faster than $\frac{1}{\text{dist}^{\text{dim}}}$. However, the pairwise Hamiltonian model remained intractable for constant overhead codes. Recently, [Bagewadi and Chatterjee, PRA 2025] introduced and analyzed the generalized hidden Markov random field (MRF) model, which provably captures all stationary distributions, including long-range correlations [Kunsch et al, Ann. App. Prob. 1995]. It resulted in a noise threshold in the case of long-range correlation, for memory corrected by the linear-distance Tanner codes [Leverrier and Zemor, FOCS 2022] for super-polynomial time. In this paper, we prove a similar result for square-root distance qLDPC codes and provide an explicit expression for the noise threshold in terms of the code rate, for up to $o(\sqrt{\text{\#qubits}})$ scaling of the total correlation of error at a location with errors at other locations.

🇯🇵Japan launches its first homegrown Quantum Computer.
The new system, which went live on July 28, replaces all previously imported components with homegrown technologies, University of Osaka representatives said in a statement. It will also run on open-source software developed in #Japan, called the Open Quantum Toolchain for Operators and Users [#OQTOPUS].

A new Frontier of Computing.
Quantum computing has the potential to outpace the world's fastest supercomputers and solve problems by making calculations and running simulations far beyond what technology is capable of today. Scientists speculate that quantum computers could be useful in drug discovery, easing traffic flows through a city, and finding the best delivery routes for a logistics company, among plenty of other endeavors.
This is because it can process calculations in parallel, rather than in sequence, by tapping into the weird laws of quantum mechanics. The idea is that the more qubits added to a system, the more powerful the system becomes.
👾However, there are plenty of barriers to simply adding qubits to quantum computers — in particular, scientists are trying to solve the extremely high error rate that occurs during calculations. For this reason, most research is currently centered on quantum error correction [QEC].👾
⁉️Japan's first quantum computer was showcased at Expo 2025, held in Osaka from Aug. 14 to Aug. 20..At the exhibition, organizers showcased key components in the quantum computer. Visitors could connect to the system remotely through the cloud and run basic quantum programs. The exhibit also included interactive elements enabling visitors to explore quantum entanglement and other quantum phenomena.⁉️](https://files.mastodon.social/cache/media_attachments/files/115/219/532/037/624/863/original/547ccb754cba80f7.jpeg)
