Quantum Many-Body Computation on a Small Quantum Computer
Abstract: What can we do on a small quantum computer with O(10) qubits? We propose a variational scheme to study ground state properties of quantum many-body systems on small scale near-term noisy q...

Quantum Journal Club: Rapid Driven Reset of a Qubit Readout Resonator
Abstract: 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 di...

Quantum Journal Club：Two-Component Structure in the Entanglement Spectrum of Hig
Abstract: We study the entanglement spectrum of highly excited eigenstates of two known models that exhibit a many-body localization transition, namely the one-dimensional random-field Heisenberg mod...
