Quantum 7, 1072 (2023). https://doi.org/10.22331/q-2023-08-03-1072 Quantum computing is a promising way to systematically solve the longstanding computational problem, the ground state of a many-body fermion system. Many efforts have been made to realise certain forms […]
Quantum 7, 1071 (2023). https://doi.org/10.22331/q-2023-08-01-1071 Integrated photonics is an essential technology for optical quantum computing. Universal, phase-stable, reconfigurable multimode interferometers (quantum photonic processors) enable manipulation of photonic quantum states and are one of the main […]
Quantum 7, 1070 (2023). https://doi.org/10.22331/q-2023-07-27-1070 We perform a detailed analysis of the possible violation of various Bell-type inequalities for systems of vector boson-antiboson pairs. Considering the general case of an overall scalar state of the […]
Quantum 7, 1069 (2023). https://doi.org/10.22331/q-2023-07-26-1069 Recently Chen and Gao [15] proposed a new quantum algorithm for Boolean polynomial system solving, motivated by the cryptanalysis of some post-quantum cryptosystems. The key idea of their approach is […]
Quantum 7, 1068 (2023). https://doi.org/10.22331/q-2023-07-26-1068 We study continuous variable systems, in which quantum and classical degrees of freedom are combined and treated on the same footing. Thus all systems, including the inputs or outputs to […]
Quantum 7, 1067 (2023). https://doi.org/10.22331/q-2023-07-25-1067 Simulating the time-evolution of a Hamiltonian is one of the most promising applications of quantum computers. Multi-Product Formulas (MPFs) are well suited to replace standard product formulas since they scale […]
Quantum 7, 1066 (2023). https://doi.org/10.22331/q-2023-07-25-1066 Quantum computers provide new avenues to access ground and excited state properties of systems otherwise difficult to simulate on classical hardware. New approaches using subspaces generated by real-time evolution have […]
Quantum 7, 1065 (2023). https://doi.org/10.22331/q-2023-07-25-1065 Whether it is at the fabrication stage or during the course of the quantum computation, e.g. because of high-energy events like cosmic rays, the qubits constituting an error correcting code […]
Quantum 7, 1064 (2023). https://doi.org/10.22331/q-2023-07-25-1064 Discrimination between objects, in particular quantum states, is one of the most fundamental tasks in (quantum) information theory. Recent years have seen significant progress towards extending the framework to point-to-point […]
Quantum 7, 1063 (2023). https://doi.org/10.22331/q-2023-07-20-1063 Quantum systems can be dynamically controlled using time-periodic external fields, leading to the concept of Floquet engineering, with promising technological applications. Computing Floquet energy spectra is harder than only computing […]
