Quantum 9, 1866 (2025). https://doi.org/10.22331/q-2025-09-29-1866 We present $tt{QuantumToolbox.jl}$, an open-source Julia package for simulating open quantum systems. Designed with a syntax familiar to users of $tt{QuTiP}$ (Quantum Toolbox in Python), it harnesses Julia’s high-performance ecosystem […]
Quantum 9, 1865 (2025). https://doi.org/10.22331/q-2025-09-29-1865 We introduce the Sequency Hierarchy Truncation (SeqHT) scheme for reducing the resources required for state preparation and time evolution in quantum simulations, based upon a truncation in sequency. For the […]
Dear Quantum community, We are aware that Google Scholar has recently stopped indexing Quantum publications. We have identified the cause of the problem, and are working towards a solution. Thank you for your warnings and […]
Quantum 9, 1864 (2025). https://doi.org/10.22331/q-2025-09-24-1864 We prove that adaptive strategies offer no advantage over non-adaptive ones for learning and testing Pauli channels using entangled inputs. This key observation allows us to characterize the query complexity […]
Quantum 9, 1863 (2025). https://doi.org/10.22331/q-2025-09-24-1863 Memory or time-non-local effects in open quantum dynamics pose theoretical as well as practical challenges in the understanding and control of noisy quantum systems. While there has been a comprehensive […]
Quantum 9, 1862 (2025). https://doi.org/10.22331/q-2025-09-24-1862 We introduce an explicit construction for a key distribution protocol in the Quantum Computational Timelock (QCT) security model, where one assumes that computationally secure encryption may only be broken after […]
Quantum 9, 1861 (2025). https://doi.org/10.22331/q-2025-09-18-1861 Non-reciprocal couplings or drivings are known to induce steady-state, directional, amplification in driven-dissipative bosonic lattices. This amplification phenomenon has been recently linked to the existence of a non-zero topological invariant […]
Quantum 9, 1860 (2025). https://doi.org/10.22331/q-2025-09-16-1860 Among the cost metrics characterizing a quantum circuit, the $T$-count stands out as one of the most crucial as its minimization is particularly important in various areas of quantum computation […]
Quantum 9, 1859 (2025). https://doi.org/10.22331/q-2025-09-16-1859 We show how the Loschmidt echo of a product state after a quench to a conformal invariant critical point and its leading finite time corrections can be predicted by using […]
Quantum 9, 1858 (2025). https://doi.org/10.22331/q-2025-09-15-1858 Magic State Distillation (MSD) has been a research focus for fault-tolerant quantum computing due to the need for non-Clifford resource in gaining quantum advantage. Although many of the MSD protocols […]
