Quantum 8, 1297 (2024). https://doi.org/10.22331/q-2024-03-21-1297 Loading functions into quantum computers represents an essential step in several quantum algorithms, such as quantum partial differential equation solvers. Therefore, the inefficiency of this process leads to a major […]
Quantum 8, 1296 (2024). https://doi.org/10.22331/q-2024-03-21-1296 Simulating the dynamics of large quantum systems is a formidable yet vital pursuit for obtaining a deeper understanding of quantum mechanical phenomena. While quantum computers hold great promise for speeding […]
Quantum 8, 1295 (2024). https://doi.org/10.22331/q-2024-03-21-1295 Although local Hamiltonians exhibit local time dynamics, this locality is not explicit in the Schrödinger picture in the sense that the wavefunction amplitudes do not obey a local equation of […]
Quantum 8, 1294 (2024). https://doi.org/10.22331/q-2024-03-21-1294 Semiconductor quantum dots operated dynamically are the basis of many quantum technologies such as quantum sensors and computers. Hence, modelling their electrical properties at microwave frequencies becomes essential to simulate […]
Quantum 8, 1293 (2024). https://doi.org/10.22331/q-2024-03-21-1293 We study classical shadows protocols based on randomized measurements in $n$-qubit entangled bases, generalizing the random Pauli measurement protocol ($n = 1$). We show that entangled measurements ($ngeq 2$) enable […]

Quantum 8, 1291 (2024). https://doi.org/10.22331/q-2024-03-20-1291 Dissipation induced by interactions with an external environment typically hinders the performance of quantum computation, but in some cases can be turned out as a useful resource. We show the […]
Quantum 8, 1290 (2024). https://doi.org/10.22331/q-2024-03-20-1290 Many applications of the emerging quantum technologies, such as quantum teleportation and quantum key distribution, require singlets, maximally entangled states of two quantum bits. It is thus of utmost importance […]
Quantum 8, 1289 (2024). https://doi.org/10.22331/q-2024-03-20-1289 We consider a quantum system that is being continuously monitored, giving rise to a measurement signal. From such a stream of data, information needs to be inferred about the underlying […]
Quantum 8, 1288 (2024). https://doi.org/10.22331/q-2024-03-20-1288 We propose a unifying paradigm for analyzing and constructing topological quantum error correcting codes as dynamical circuits of geometrically local channels and measurements. To this end, we relate such circuits […]
