Quantum 8, 1470 (2024). https://doi.org/10.22331/q-2024-09-11-1470 We consider models of quantum computation that involve operations performed on some fixed resourceful quantum state. Examples that fit this paradigm include magic state injection and measurement-based approaches. We introduce […]
A team of computer scientists at Google Quantum AI has demonstrated a type of quantum memory for a quantum computer that produces far fewer errors than others. The group has published a paper on the […]
Quantum 8, 1469 (2024). https://doi.org/10.22331/q-2024-09-11-1469 Here, we investigate the fractal-lattice Hubbard model using various numerical methods: exact diagonalization, the self-consistent diagonalization of a (mean-field) Hartree-Fock Hamiltonian and state-of-the-art Auxiliary-Field Quantum Monte Carlo. We focus on […]
Insider Brief The QLLIANSE initiative is launching to establish the Southeastern U.S. as a major hub for quantum technology, focusing on building a people-based quantum ecosystem to support economic growth and innovation. The initiative has […]
