Quantum 10, 2223 (2026). https://doi.org/10.22331/q-2026-10-01-2223 We present a universal framework for simulating $N$-dimensional linear Itô stochastic differential equations (SDEs) on quantum computers with additive or multiplicative noises. Building on a unitary dilation technique, we establish […]
Quantum 10, 2222 (2026). https://doi.org/10.22331/q-2026-10-01-2222 Robust self-testing in non-local games allows a classical referee to certify that two untrustworthy players are able to perform a specific quantum strategy up to high precision. Proving robust self-testing […]
Quantum 10, 2221 (2026). https://doi.org/10.22331/q-2026-09-30-2221 There exists a stark tension among different formulations of quantum theory as some are inherently time-symmetric while others are time-asymmetric. This tension is crisply captured when considering physical theories as […]
Quantum 10, 2220 (2026). https://doi.org/10.22331/q-2026-09-30-2220 Studies have shown that quantum states reside in a Hilbert space bundle. When a quantum system depends on continuous external parameters, these parameters define additional dimensions in the base space […]
Quantum 10, 2219 (2026). https://doi.org/10.22331/q-2026-09-30-2219 Qubit shuttling promises to advance some quantum computing platforms to the qubit register sizes needed for effective quantum error correction (QEC), but also introduces additional errors whose impact must be […]
Quantum 10, 2218 (2026). https://doi.org/10.22331/q-2026-09-30-2218 If a unitary transformation has a circuit representation with no directed path from input $a$ to output $b$, then $a$ does not influence $b$ through the overall unitary. Conversely, if […]
Quantum 10, 2217 (2026). https://doi.org/10.22331/q-2026-09-29-2217 Quantum phase transitions reveal deep insights into the behavior of many-body quantum systems, but identifying these transitions without prior knowledge of order parameters remains a significant challenge. In this work, […]
Quantum 10, 2216 (2026). https://doi.org/10.22331/q-2026-09-24-2216 The encoding of lattice gauge theories onto quantum computers requires a discretization of the gauge field’s Hilbert space on each link, which presents errors with respect to the Kogut–Susskind limit. […]
Quantum 10, 2215 (2026). https://doi.org/10.22331/q-2026-09-24-2215 The history based formalism known as Quantum Measure Theory (QMT) generalizes the concept of probability-measure so as to incorporate quantum interference. The resulting quantum measure $mu$ is defined for arbitrary […]
Quantum 10, 2214 (2026). https://doi.org/10.22331/q-2026-09-21-2214 We study quantitatively the interplay between entanglement and non-stabilizer resources in violating the CHSH inequalities. We show that, while non-stabilizer resources are necessary, they must have a specific structure, namely […]
