Venturus, one of the largest science and technology institutes in Brazil, and QuEra Computing, a company developing quantum computers using neutral atoms, have announced a strategic partnership to promote quantum computing innovation in Latin America. […]
Data assimilation is an important mathematical discipline in earth sciences, particularly in numerical weather prediction (NWP). However, conventional data assimilation methods require significant computational resources. To address this, researchers developed a novel method to solve […]
On June 7, 2024, the United Nations proclaimed 2025 as the International Year of Quantum Science and Technology (IYQ). This initiative aims to increase public awareness of quantum science and its applications. The year 2025 […]
Quantum 8, 1372 (2024). https://doi.org/10.22331/q-2024-06-13-1372 We generalize the concept of folding from surface codes to CSS codes by considering certain dualities within them. In particular, this gives a general method to implement logical operations in […]
Quantum 8, 1371 (2024). https://doi.org/10.22331/q-2024-06-13-1371 We propose the regularized compressed double factorization (RC-DF) method to classically compute compressed representations of molecular Hamiltonians that enable efficient simulation with noisy intermediate scale (NISQ) and error corrected quantum […]
Quantum 8, 1370 (2024). https://doi.org/10.22331/q-2024-06-13-1370 Here we study the unitary groups that can be constructed using elements from the qubit Clifford Hierarchy. We first provide a necessary and sufficient canonical form that semi-Clifford and generalized […]
Quantum 8, 1369 (2024). https://doi.org/10.22331/q-2024-06-13-1369 Time-dependent linear differential equations are a common type of problem that needs to be solved in classical physics. Here we provide a quantum algorithm for solving time-dependent linear differential equations […]
