**An exceptionally accessible introduction to quantum field theory**\nQuantum field theory is by far the most spectacularly successful theory in physics, but also one of the most mystifying. __Quantum Field Theory, as Simply as Possible__ provides an essential primer on the subject, giving ...
Quantum theory provides an extremely accurate description of fundamental processes in physics. It thus seems likely that the theory is applicable beyond the, mostly microscopic, domain in which it has been tested experimentally. Here, we propose a Gedank
Quantum field theory (QFT) shares many of its philosophical problems with quantum mechanics. This applies in particular to the quantum measurement process and the connected interpretive problems, to which QFT contributes hardly any new aspects, let alone solutions. The question as to how the objects...
Theory research is forward-looking and predictive. Theorists such as Geoffrey Hinton laid the foundations of the current AI revolution. But decades later, with an abundance of computing hardware, AI has become much more of an empirical field. I look forward to the day that quantum hardware reach...

The proportion of this overhead as a fraction of total processing time available increases as the quanta get smaller, and thus, the system can do less useful work in a given time period, so the optimal context switching rate is not simply the fastest rate that can be achieved. Sign in ...
Although we do not have a complete theory of Quantum Gravity, there are several regimes in which we require the metric to be a dynamical degree of freedom and General Relativity (GR), or alternative theories, to be quantized as an effective field theory. The most prominent of these regimes ...
Quantum field theory (QFT) provides an efficient method to compute then-th Rényi entropy with integern>1, which is defined as [3] Sn(ρA)≡11−nlnTr(ρAn). (1) The computation is done by replicating the path integral representation of the reduced density matrixρAbyntimes. This st...
