Quantum Journal Club: Improved superconducting qubit coherence with high-temperature substrate annealing
内容： We assess independently the impact of high-temperature substrate annealing and metal deposition conditions on the coherence of transmon qubits in the standard 2D circuit-QED architecture. We re...

Quantum Journal Club: Quantum Rabi Model with Trapped Ions
内容： We propose the quantum simulation of the quantum Rabi model in all parameter regimes by means of detuned bichromatic sideband excitations of a single trapped ion. We show that current setups ca...

Loop Quantum Gravity and Quantum Geometry
内容： Loop Quantum Gravity is a promising theory of non-perturbative quantum gravity. It is also a theory of quantum space and time. In this talk, the motivations, ideas, and concepts in Loop Quantum...

Entangling coherent states into a maximally entangled qudits and/or qudit cluster states
内容： Optically coherent states can be interpreted as qudits with arbitrary integer d. Weak cross-Kerr nonlinear interaction can maximally entangle two coherent states and this can be used for variou...

Quantum gate operation in the circuit-QED lattice with circulator function
内容： We propose a scheme for a scalable quantum computing in the circuit-quantum electrodynamics(QED) architecture. In the Kagome lattice of qubits three qubits are connected to each other through a...
