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 control and quantum information processing with a superconducting cavity
内容： We propose an efficient protocol to perform universal quantum control of an oscillator mode (e.g. cavity mode) off-resonantly coupled to an ancillary qubit. With an excitation number truncation...
