Quantum 10, 2213 (2026). https://doi.org/10.22331/q-2026-09-21-2213 The possibility of nonclassicality in networks unrelated to Bell’s original eponymous theorem has recently attracted significant interest. Here, we identify a sufficient condition for being “outside the shadow of Bell’s […]
Quantum 10, 2212 (2026). https://doi.org/10.22331/q-2026-09-21-2212 Efficiently implementing Clifford circuits is crucial for quantum error correction and quantum algorithms. Linear reversible circuits, equivalent to circuits composed of CNOTxspace gates, have important applications in classical computing. In […]
Quantum 10, 2211 (2026). https://doi.org/10.22331/q-2026-09-18-2211 We study multiparty entanglement near measurement induced phase transitions (MIPTs), which arise in ensembles of local quantum circuits built with unitaries and measurements. In contrast to equilibrium quantum critical transitions, […]
Quantum 10, 2210 (2026). https://doi.org/10.22331/q-2026-09-18-2210 According to Aumann’s celebrated theorem, rational agents cannot agree to disagree. In other words, agents who once shared a common prior probability distribution and who have common knowledge about their […]
Quantum 10, 2209 (2026). https://doi.org/10.22331/q-2026-09-18-2209 Gibbs state preparation, or Gibbs sampling, is a key computational technique extensively used in physics, statistics, and other scientific fields. Recent efforts for designing fast mixing Gibbs samplers for quantum […]
Quantum 10, 2208 (2026). https://doi.org/10.22331/q-2026-09-10-2208 The preparation of quantum states is one of the most fundamental tasks in quantum computing, and a key primitive in many quantum algorithms. Of particular interest to areas such as […]
Quantum 10, 2207 (2026). https://doi.org/10.22331/q-2026-09-10-2207 Reliable quantum memory under circuit-level noise requires decoders that can process syndrome information continuously and at a rate comparable to its generation. In practical quantum error correction (QEC), repeated syndrome […]
Quantum 10, 2206 (2026). https://doi.org/10.22331/q-2026-09-10-2206 The practical applicability of a recent Carleman-linearization-based quantum algorithm for solving ordinary differential equations (ODEs) with quadratic nonlinearities is investigated for the nonlinear electrostatic Vlasov equation with Krook-type collision operators.
