Quantum 8, 1361 (2024). https://doi.org/10.22331/q-2024-05-27-1361 In this paper, we present a learning algorithm aimed at learning states obtained from computational basis states by Clifford circuits doped with a finite number $t$ of $T$-gates. The algorithm […]
Quantum 8, 1360 (2024). https://doi.org/10.22331/q-2024-05-23-1360 Rigorous derivations of the approach of individual elements of large isolated systems to a state of thermal equilibrium, starting from arbitrary initial states, are exceedingly rare. This is particularly true […]
Quantum 8, 1359 (2024). https://doi.org/10.22331/q-2024-05-23-1359 We propose a protocol for the scalable quantum simulation of SU($N$)$times$U(1) lattice gauge theories with alkaline-earth like atoms in optical lattices in both one- and two-dimensional systems. The protocol exploits […]
Quantum 8, 1358 (2024). https://doi.org/10.22331/q-2024-05-23-1358 Quantum state reconstruction using Neural Quantum States has been proposed as a viable tool to reduce quantum shot complexity in practical applications, and its advantage over competing techniques has been […]
Quantum 8, 1357 (2024). https://doi.org/10.22331/q-2024-05-23-1357 The spin-boson model usually considers a spin coupled to a single bosonic bath. However, some physical situations require coupling of the spin to multiple environments. For example, spins interacting with […]
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 […]
