Quantum 7, 1124 (2023). https://doi.org/10.22331/q-2023-09-26-1124 Non-Markovian dynamics are characterized by information backflows, where the evolving open quantum system retrieves part of the information previously lost in the environment. Hence, the very definition of non-Markovianity implies […]
Opening new possibilities for quantum sensors, atomic clocks and tests of fundamental physics, JILA researchers have developed new ways of “entangling” or interlinking the properties of large numbers of particles. In the process they have […]
Quantum 7, 1123 (2023). https://doi.org/10.22331/q-2023-09-26-1123 A common approach to studying the performance of quantum error correcting codes is to assume independent and identically distributed single-qubit errors. However, the available experimental data shows that realistic errors […]
Insider Brief Scientists report they have made meaningful progress in unravelling one of the most enigmatic phenomena in physics – superconductivity. The work revolves around the measurement of the “Loschmidt amplitude,” a fundamental quantum concept […]
Marie Delattre was studying the sexual reproduction practices of microscopic worms when she noticed something unexpected. Under the microscope, an embryo of the nematode Mesorhabditis belari was dividing as it should, progressing from one cell […]
Quantum 7, 1122 (2023). https://doi.org/10.22331/q-2023-09-26-1122 Recently, a class of fractal surface codes (FSCs), has been constructed on fractal lattices with Hausdorff dimension $2+epsilon$, which admits a fault-tolerant non-Clifford CCZ gate [1]. We investigate the performance […]
Quantum 7, 1121 (2023). https://doi.org/10.22331/q-2023-09-26-1121 We generalize the Quantum Approximate Optimization Algorithm (QAOA) of Farhi et al. (2014) to allow for arbitrary separable initial states with corresponding mixers such that the starting state is the […]
The International Max Planck Research School for Chemistry and Physics of Quantum Materials is a joint PhD program between the Max Planck Institute for Chemical Physics of Solids in Dresden, Germany, Technische Universität Dresden and […]
We are a newly started laboratory at Chalmers University of Technology in Sweden. We will create interfaces between cold atoms, light and motion using nanofabricated devices. We will use these devices to create quantum states […]
Scientists at the National Institute of Standards and Technology (NIST) with colleagues elsewhere have employed neutron imaging and a reconstruction algorithm to reveal for the first time the 3D shapes and dynamics of very small […]
