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 […]
Research teams led by Prof. Zeng Changgan and Zhang Hui from the Hefei National Laboratory for Physical Sciences at the Microscale, the University of Science and Technology of China (USTC) of the Chinese Academy of […]
Spontaneous parametric down-conversion (SPDC), as a source of entangled photons, is of great interest for quantum physics and quantum technology, but so far it could be only implemented in solids. Click to rate this post! […]
Quantum 8, 1368 (2024). https://doi.org/10.22331/q-2024-06-13-1368 Using local operations and classical communication (LOCC), entanglement can be manipulated but not created. However, entanglement can be $embezzled$. In this work, we completely characterize universal embezzling families and demonstrate […]
Quantum 8, 1367 (2024). https://doi.org/10.22331/q-2024-06-13-1367 Mitigation and calibration schemes are central to maximize the computational reach of today’s Noisy Intermediate Scale Quantum (NISQ) hardware, but these schemes are often specialized to exclusively address either coherent […]
Researchers at QuTech have found a way to make Majorana particles in a two-dimensional plane. This was achieved by creating devices that exploit the combined material properties of superconductors and semiconductors. The inherent flexibility of […]
