Quantum 7, 1078 (2023). https://doi.org/10.22331/q-2023-08-09-1078 Quantum computers hold great promise to enhance machine learning, but their current qubit counts restrict the realisation of this promise. To deal with this limitation the community has produced a […]
Quantum 7, 1077 (2023). https://doi.org/10.22331/q-2023-08-08-1077 Pauli spin blockade (PSB) can be employed as a great resource for spin qubit initialisation and readout even at elevated temperatures but it can be difficult to identify. We present […]
Quantum 7, 1076 (2023). https://doi.org/10.22331/q-2023-08-08-1076 Recently, Zhong et al. [1, 2] performed landmark Gaussian boson sampling experiments with up to 144 modes using threshold detectors. The authors claim to have achieved quantum computational advantage with […]
Quantum 7, 1075 (2023). https://doi.org/10.22331/q-2023-08-08-1075 The Shor fault-tolerant error correction (FTEC) scheme uses transversal gates and ancilla qubits prepared in the cat state in syndrome extraction circuits to prevent propagation of errors caused by gate […]
Quantum 7, 1074 (2023). https://doi.org/10.22331/q-2023-08-03-1074 While the terms “redundancy” and “consensus” are often used as synonyms in the context of quantum objectivity, we show here that these should be understood as two related but distinct […]
Quantum 7, 1073 (2023). https://doi.org/10.22331/q-2023-08-03-1073 Science is rich in abstract concepts that capture complex processes in astonishingly simple ways. A prominent example is the reduction of molecules to simple graphs. This work introduces a design […]
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 […]
