Quantum 8, 1356 (2024). https://doi.org/10.22331/q-2024-05-23-1356 The Bethe ansatz represents an analytical method enabling the exact solution of numerous models in condensed matter physics and statistical mechanics. When a global symmetry is present, the trial wavefunctions […]
Quantum 8, 1355 (2024). https://doi.org/10.22331/q-2024-05-23-1355 Superconducting transition-edge sensors (TES) are extremely sensitive microcalorimeters used as photon detectors with unparalleled energy resolution. They have found application from measuring astronomical spectra through to determining the quantum property […]
Quantum 8, 1354 (2024). https://doi.org/10.22331/q-2024-05-22-1354 We present the first high performance compiler for very large scale quantum error correction: it translates an arbitrary quantum circuit to surface code operations based on lattice surgery. Our compiler […]
Quantum 8, 1353 (2024). https://doi.org/10.22331/q-2024-05-22-1353 We introduce the $textit{resource marginal problems}$, which concern the possibility of having a resource-free target subsystem compatible with a $given$ collection of marginal density matrices. By identifying an appropriate choice […]
Quantum 8, 1352 (2024). https://doi.org/10.22331/q-2024-05-22-1352 The Quantum Max Cut (QMC) problem has emerged as a test-problem for designing approximation algorithms for local Hamiltonian problems. In this paper we attack this problem using the algebraic structure […]
Quantum 8, 1351 (2024). https://doi.org/10.22331/q-2024-05-21-1351 Magic, or nonstabilizerness, characterizes the deviation of a quantum state from the set of stabilizer states, playing a fundamental role in quantum state complexity and universal fault-tolerant quantum computing. However, […]
Quantum 8, 1350 (2024). https://doi.org/10.22331/q-2024-05-21-1350 We propose efficient algorithms for classically simulating fermionic linear optics operations applied to non-Gaussian initial states. By gadget constructions, this provides algorithms for fermionic linear optics with non-Gaussian operations. We […]
Quantum 8, 1349 (2024). https://doi.org/10.22331/q-2024-05-16-1349 A set of orthogonal product states is strongly nonlocal if it is locally irreducible in every bipartition, which shows the phenomenon of strong quantum nonlocality without entanglement. Although such a […]
Quantum 8, 1348 (2024). https://doi.org/10.22331/q-2024-05-14-1348 Motivated by quantum network applications over classical channels, we initiate the study of $n$-party resource states from which LOCC protocols can create EPR-pairs between any $k$ disjoint pairs of parties. […]
Quantum 8, 1347 (2024). https://doi.org/10.22331/q-2024-05-14-1347 Magic is a property of a quantum state that characterizes its deviation from a stabilizer state, serving as a useful resource for achieving universal quantum computation e.g., within schemes that […]
