Abstract book
... Quantum Optics has focused for many years on uncovering what is specifically non-classical about light fields, from the early days of quantum mechanics to current work on quantum information processing. Much of this work has concentrated on the role of discreteness, of the limits of the uncertainty ...

Quantum Theory: Concepts and Methods
... This book differs from von Neumann’s classic treatise in many respects. von Neumann was concerned with “measurable quantities.” This is a neo-classical attitude: supposedly, there are “physical quantities” which we measure, and their measurements disturb each other. Here, I merely assume that we per ...

System Science of Virtual Reality
... The underlying concepts are relatively easy to grasp if approached with persistence and genuine scepticism8 . Hence the discussion will be kept as simple and approachable as possible and will use concrete examples. If there is a choice between approaches, the more accessible approach is used wherev ...

Heisenberg Uncertainty Principle
... The measuring process in QM always effects the subjected quantum particle. The more exact the measurement the greater the effect. Reducing the accuracy reduces the effect on the particle. It is impossible in principle to make the effect arbitrarily small. ...

Aalborg Universitet The effect of time-dependent coupling on non-equilibrium steady states
... equilibrium. In the remote future the system is fully coupled. We define and compute the non equilibrium steady state (NESS) generated by this evolution. We show that when restricted to the subspace of absolute continuity of the fully coupled system, the state does not depend at all on the switching ...

On quantum obfuscation - University of Maryland Institute for
... The years following the Barak et al. result saw some limited progress in theoretical obfuscation. It was proved possible for some limited forms of functionality [16, 37], and some additional limits were placed, e.g., on black-box obfuscation with auxiliary input [24]. An important step in formulatin ...

One does not need to worry about issues such as different band masses for the heavy and light holes as in typical semiconductor structures [9]. The spectra are thus much simpler, and i ...
