Quantum Journal Club: Rapid Driven Reset of a Qubit Readout Resonator
内容： Using a circuit QED device, we demonstrate a simple qubit measurement pulse shape that yields fast ring-up and ring-down of the readout resonator regardless of the qubit state. The pulse differ...

Quantum Journal Club: Simulating Hamiltonian Dynamics with a Truncated Taylor Se
内容： We describe a simple, efficient method for simulating Hamiltonian dynamics on a quantum computer by approximating the truncated Taylor series of the evolution operator. Our method can simulate ...

Quantum Journal Club: Resolving remote nuclear spins in a noisy bath by dynamica
内容： We experimentally resolve several weakly coupled nuclear spins in diamond using a series of dynamical decoupling controls. Some nuclear spin signals, hidden by decoherence under ordinary dynami...

Quantum Journal Club: Single-photon continuous-variable quantum key distribution
内容： We propose a new quantum key distribution protocol in which information is encoded on continuous variables of a single photon. In this protocol, Alice randomly encodes her information on either...
