内容: Spin echo is a powerful technique to extend atomic or nuclear coherence times by overcoming the dephasing due to inhomogeneous broadenings. However, there are disputes about the feasibility of ...
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 ...
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...
内容: Probing the Standard Model (SM) of particle physics is generally associated with high energy accelerator based experiments. However, till date the best test of the field theory has been through...
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...
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...
