Quantum 9, 1633 (2025). https://doi.org/10.22331/q-2025-02-17-1633 Quantum Floquet engineering (QFE) seeks to generalize the control of quantum systems with classical external fields, widely known as Semi-Classical Floquet engineering (SCFE), to quantum fields. However, to faithfully capture […]
Quantum 9, 1632 (2025). https://doi.org/10.22331/q-2025-02-17-1632 The development of practical, high-performance decoding algorithms reduces the resource cost of fault-tolerant quantum computing. Here we propose a decoder for the surface code that finds low-weight correction operators for […]
Quantum 9, 1631 (2025). https://doi.org/10.22331/q-2025-02-11-1631 Strongly-correlated quantum many-body systems are difficult to study and simulate classically. We recently proposed a variational quantum eigensolver (VQE) based on the multiscale entanglement renormalization ansatz (MERA) with tensors constrained […]
Quantum 9, 1630 (2025). https://doi.org/10.22331/q-2025-02-11-1630 Accurate simulations of vibrational molecular spectra are expensive on conventional computers. Compared to the electronic structure problem, the vibrational structure problem with quantum computers is less investigated. In this work […]
Quantum 9, 1629 (2025). https://doi.org/10.22331/q-2025-02-11-1629 Recent results in relativistic quantum information and quantum thermodynamics have independently shown that in the quantum regime, a system may fail to thermalise when subject to quantum-controlled application of the […]
Quantum 9, 1628 (2025). https://doi.org/10.22331/q-2025-02-11-1628 What does it mean for a causal structure to be `unknown’? Can we even talk about `repetitions’ of an experiment without prior knowledge of causal relations? And under what conditions […]
Quantum 9, 1627 (2025). https://doi.org/10.22331/q-2025-02-10-1627 Recently, the dynamics of quantum systems that involve both unitary evolution and quantum measurements have attracted attention due to the exotic phenomenon of measurement-induced phase transitions. The latter refers to […]
Quantum 9, 1626 (2025). https://doi.org/10.22331/q-2025-02-10-1626 Hamiltonian encoding is a methodology for revealing the mechanism behind the dynamics governing controlled quantum systems. In this paper, following Mitra and Rabitz [9], we define mechanism via pathways of […]
Quantum 9, 1625 (2025). https://doi.org/10.22331/q-2025-02-10-1625 In the ongoing effort towards a scalable quantum computer, multiple technologies have been proposed. Some of them exploit topological materials to process quantum information. In this work, we propose a […]
Quantum 9, 1624 (2025). https://doi.org/10.22331/q-2025-02-06-1624 Hamiltonian simulation is a domain where quantum computers have the potential to outperform their classical counterparts. One of the main challenges of such quantum algorithms is increasing the system size, […]
