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 […]
A quantum internet would essentially be unhackable. In the future, sensitive information—financial or national security data, for instance, as opposed to memes and cat pictures—would travel through such a network in parallel to a more […]
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 […]
Quantum 8, 1346 (2024). https://doi.org/10.22331/q-2024-05-14-1346 Transitions out of the ground space limit the performance of quantum adiabatic algorithms, while hardware imperfections impose stringent limitations on the circuit depth. We propose an adiabatic echo verification protocol […]
