Quantum Journal Club: Photonic Boson Sampling in a Tunable Circuit
内容： Quantum computers are unnecessary for exponentially efficient computation or simulation if the Extended Church-Turing thesis is correct. The thesis would be strongly contradicted by physical de...

Quantum Journal Club: Quantum Dynamics with Spatiotemporal Control of Interactio
内容： Optical control of atomic interactions in quantum gases is a long-sought goal of cold atom research. Previous experiments have been hindered by rapid decay of the quantum gas and parasitic defo...

Quantum Journal Club: Comparing and combining measurement-based and driven-dissi
内容： We demonstrate and contrast two approaches to the stabilization of qubit entanglement by feedback. Our demonstration is built on a feedback platform consisting of two superconducting qubits cou...

Jaynes-Cummings-Hubbard model and bosonic-particle system using trapped ions
内容： Recent advances in quantum technology enabled us to simulate a certain quantum system with another well-controlled system (quantum simulation or analog quantum computation). Systems of trapped ...

Quantum Gravity with its applications
内容： After a brief review of current status of quantum gravity, I will focus largely on its most successful formulation in which the gravity in d+1 dimensional asymptotic AdS spacetime is dual to d ...

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 ...
