DOI: 10.1126/sciadv.abl6698
Abstract: We report high qubit coherence as well as low cross-talk and single-qubit gate errors in a superconducting circuit architecture that promises to be tileable to two-dimensional (2D) lattices of qubits. The architecture integrates an inductively… read more here.

DOI: 10.1140/epjc/s10052-019-7514-9
Abstract: Hawking radiation is one of the most intriguing and elusive predictions of quantum field theory in curved spacetime. Previous works simulating Hawking radiation have been mostly based on Unruh’s scenario, where the propagation of quantum… read more here.
