DNA is nature’s computing device. Unlike data centers, DNA is incredibly compact. These molecules package an entire organism’s genetic blueprint into tiny but sophisticated structures inside each cell. Kept cold—say, inside a freezer or in […]

Quantum 8, 1479 (2024). https://doi.org/10.22331/q-2024-09-19-1479 In order to substantiate claims of quantum computational advantage, it is crucial to develop efficient methods for validating the experimental data. We propose a test of the correct functioning of […]
Quantum 8, 1478 (2024). https://doi.org/10.22331/q-2024-09-19-1478 Recent advancements in multi-mode Gottesman-Kitaev-Preskill (GKP) codes have shown great promise in enhancing the protection of both discrete and analog quantum information. This broadened range of protection brings opportunities beyond […]
Quantum 8, 1477 (2024). https://doi.org/10.22331/q-2024-09-19-1477 Quantum Krylov subspace diagonalization (QKSD) is an emerging method used in place of quantum phase estimation in the early fault-tolerant era, where limited quantum circuit depth is available. In contrast […]
Quantum 8, 1476 (2024). https://doi.org/10.22331/q-2024-09-19-1476 In this paper, we propose a novel bipartite entanglement purification protocol built upon hashing and upon the guessing random additive noise decoding (GRAND) approach recently devised for classical error correction […]
Quantum 8, 1475 (2024). https://doi.org/10.22331/q-2024-09-17-1475 We introduce a novel method of efficiently simulating the non-equilibrium steady state of large many-body open quantum systems with highly non-local interactions, based on a variational Monte Carlo optimization of […]
Quantum 8, 1474 (2024). https://doi.org/10.22331/q-2024-09-17-1474 The Schwinger model is one of the simplest gauge theories. It is known that a topological term of the model leads to the infamous sign problem in the classical Monte […]
Quantum 8, 1473 (2024). https://doi.org/10.22331/q-2024-09-12-1473 Identical quantum particles exhibit only two types of statistics: bosonic and fermionic. Theoretically, this restriction is commonly established through the symmetrization postulate or (anti)commutation constraints imposed on the algebra of […]
Quantum 8, 1472 (2024). https://doi.org/10.22331/q-2024-09-12-1472 Nielsen’s approach to quantum state complexity relates the minimal number of quantum gates required to prepare a state to the length of geodesics computed with a certain norm on the […]
Quantum 8, 1471 (2024). https://doi.org/10.22331/q-2024-09-12-1471 The problem of efficient quantum state learning, also called shadow tomography, aims to comprehend an unknown $d$-dimensional quantum state through POVMs. Yet, these states are rarely static; they evolve due […]
