Spinor Bose-Einstein condensate as an analog simulator of molecular bending vibrations (opens the original)
Read excerpt
Quantum 10, 2226 (2026).https://doi.org/10.22331/q-2026-10-01-2226We demonstrate that spinor Bose-Einstein condensates (BECs) can be operated as an analog simulator of the two-dimensional vibron model. This algebraic model describes bending vibrations of molecules and, in the case of triatomic molecules, exhibits two phases where linear and bent configurations are stabilised. Spinor BECs can be engineered to simulate states that correspond to linear or bent triatomic molecules, with the Wigner f
GPU-Accelerated Quantum Simulation of Stabilizer Circuits (opens the original)
Read excerpt
Quantum 10, 2225 (2026).https://doi.org/10.22331/q-2026-10-01-2225We introduce new parallel algorithms for efficiently simulating stabilizer (Clifford) circuits on GPUs, with a focus on data-parallel tableau evolution and scalable handling of projective measurements. Our approach reformulates key bottlenecks in stabilizer simulation – such as Gaussian elimination and measurement updates – into GPU-tailored primitives that eliminate sequential dependencies and maximize memory coalescing. We imple
Fast Bosonic Control via Multiphoton Qubit-Oscillator Interactions (opens the original)
Read excerpt
Quantum 10, 2224 (2026).https://doi.org/10.22331/q-2026-10-01-2224We study the problem of $n$-fold rotationally symmetric bosonic state preparation, which is of great importance to bosonic quantum error correction, using a multiphoton interaction between an oscillator and an auxiliary qubit. We present an $n$-photon Law-Eberly ($n$LE) protocol that serves as an analytic baseline, alongside numerical optimal control calculations that further reduce state preparation time. We find that multiphoton
Universal Dilation of Linear Itô SDEs: Quantum Trajectories and Lindblad Simulation of Second Moments (opens the original)
Read excerpt
Quantum 10, 2223 (2026).https://doi.org/10.22331/q-2026-10-01-2223We 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 a rigorous mapping from the general linear SDEs $ dX_t = A(t) X_t dt + \sum_{j=1}^J B_j(t)X_t dW_t^j $ to stochastic Schrödinger equations (SSE) on a dilated Hilbert space. Crucially, this embedding is
Lifting the maximally-entangledness assumption in robust self-testing for synchronous games (opens the original)
Read excerpt
Quantum 10, 2222 (2026).https://doi.org/10.22331/q-2026-10-01-2222Robust 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 results becomes significantly easier when one restricts the allowed strategies to symmetric projective maximally entangled (PME) strategies, which allow natural descriptions in terms of tracial von Neumann algebras. This has bee
