Designing control pulses to generate desired unitary evolution subjugated to experimental constraints (e.g., decoherence time, bandwidth) is a common task for quantum platforms, these type of problems are often addressed in the context of quantum optimal control. Parallel Automatic Differentiation Quantum Optimal Control (PADQOC) is an open-source, Python based general quantum optimal control solver built on top of Tensorflow 2. It is designed to be fast, extensible and useful for controlling general quantum systems.
It is possible to engineer the properties of photons in an optical medium to have an effective mass and repulsive interactions so that they act like a gas of atoms. These "renormalized photons" are called polaritons. In the past decade, several experiments have demonstrated many of the canonical effects of Bose-Einstein condensation and superfluidity of polaritons.
Much of our intuition about light comes from our experience that light has very weak interaction with other light—a beam of light easily passes through another beam of light, so that the Star Wars scenes of “light sabers” bouncing off each other are just imaginary. But in solids, the properties of light can be changed dramatically, especially in solids that we design for new effects.

In this work, we develop resource-theoretic approaches to study the non-stabilizer resources in fault-tolerant quantum computation. First, we introduce a family of magic measures to quantify the amount of magic in a quantum state, several of which can be efficiently computed via convex optimization. Second, we show that two classes of states with maximal mana, a previously established magic measure, cannot be interconverted asymptotically at a rate equal to one.

The Quantum Cryptography School for Young Students (QCSYS) will run August 9-16, 2019 with students arriving August 8 and departing August 17. Apply for QCSYS and discover how the physics and mathematics of quantum mechanics and cryptography merge into one of the most exciting topics in contemporary science – quantum cryptography.
In this presentation, physical properties and possible applications of carbon based nano electro-mechanical devices (NEMS) will be introduced. Our research started from carbon nanotube based nano electro-mechanical relay structure and expanded to graphene based xylophone and drum like devices. Micro contact transfer method is applied to realize the suspended nano structures with various electrodes under the nano materials.
Computational intelligence refers to the ability of a computer to learn a specific task from data or experimental observation. It is part of the artificial intelligence area composed of three disciplines: approximate reasoning, evolutionary computation and machine learning.
