Efficient Quantum Algorithms for Simulating Lindblad Evolution
Graphs and Multi-mode Coupling: How to build a programmable, directional parametric amplifier
Jose Aumentado, National Institute of Standards and Technology, Boulder
Parametric amplification is a big deal these days, especially for research in superconducting quantum information. This is because, in principle, parametric amplifiers can amplify a signal while adding the minimum amount of noise that quantum mechanics allows. In practice, the situation is a little more complicated and the practical measurement chains can degrade this ideal performance.
