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...

Black-box Quantum Computing
Abstract: Modern programming relies on our ability to treat preprogrammed functions as black boxes - we can invoke them as subroutines without knowing their physical implementation. Here we show it i...

Linear combination of Hamiltonian simulation for non-unitary dynamics with optimal state preparation cost
Abstract: We propose a simple method for simulating a general class of non-unitary dynamics as a linear combination of Hamiltonian simulation (LCHS) problems. LCHS does not rely on converting the pro...

Measurement-based noiseless linear amplification for entanglement distillation a
Abstract: A fundamental feature of the quantum world that we live in is that (non-orthogonal) quantum states cannot be cloned. This no cloning theorem lies at the heart of quantum mechanics and is a ...
