quantumcomputing/26329_c9e4e44e33b9a57b_14.txt | where the bit depth \(c={\log }\_{2}L\) indicates the number of classical bits encoding the output value. Here, the upper bound represents the impossibility of discarding more qubits than those initially considered. As shown in Fig. 5, the advantage (namely the ratio between classical and quantum complexities) grows ap... |
quantumcomputing/24212_45e264729078187e_420.txt | Abstract *Emerging sampling algorithms based on normalizing flows have the potential to solve ergodicity problems in lattice calculations. Furthermore, it has been noted that flows can be used to compute thermodynamic quantities which are difficult to access with traditional methods. This suggests that they are also ap... |
quantumcomputing/f13a9039_0176.txt | Physics is traditionally conceived as a primarily “theoretical” activity, in the sense that it is generally thought to be the goal of physics to tell us, even if only indirectly (Fuchs (2002), pp. 5–6, Fuchs (2010), pp. 22–3), what the world is like independently of ourselves. This is not the case with every science. C... |
quantumcomputing/7af1afda_9989.txt | Computer engineers typically describe a modern computer's operation in terms of classical electrodynamics. In these "classical" computers, some components (such as semiconductors and random number generators) may rely on quantum behavior; however, because they are not isolated from their environment, any quantum inform... |
quantumcomputing/14994_bb89c4acbf2bb616_397.txt | These results show that although symmetric Turing machines of the third type have the same computing power as Turing machines, they can be essentially more efficient. Further considerations of symmetric automata show that there are intrinsic relations between operationally symmetric Turing machines and evolutionary Turin... |
quantumcomputing/4628_98bc330e6ca89479_672.txt | Suppose H(X : Y) < II(X). Then it is not possible to reconstruct X from Y, since if Z is the attempted reconstruction based only on knowledge of Y, then X —* Y —> Z must be a Markov chain, and thus H(X) > II(X : Z) by the data processing inequality. Thus Z 7 ^ X. On the other hand, if H(X: Y) = H(X), then we have H(X\Y... |
quantumcomputing/3960_6c2be0a104c001a2_41.txt | I think that what James describes here is true and thus trying to debate with these folks is pointless. What we need to do is push them aside and get on with things. They are hopelessly wrong and unwilling to try to understand the truth which they deny even exists. It’s not our unwillingness to debate them that is the ... |

quantumcomputing/34793_74dcaa7adf2cb6cc_71.txt | We have a reasonable understanding of the concept of classical computing, but the implications of quantum physics for computing and information may determine the philosophical research agenda for decades to come if not longer. Still it is already clear that the research has repercussions for traditional philosophical p... |
quantumcomputing/1e612be1_11778.txt | ACM transactions on quantum computing, 2022 As quantum computers have become available to the general public, the need has arisen to train a cohort of quantum programmers, many of whom have been developing classic computer programs for most of their career. While currently available quantum computers have less than 100... |
quantumcomputing/e6c3885d_123880.txt | Use cases: CCZ gates appear in scenarios where a conditional phase based on two qubits is needed. A notable application is in certain quantum oracles and amplitude amplification routines. For instance, Grover's search algorithm uses an oracle that marks the correct solution state by flipping its phase. If the solutio... |
quantumcomputing/6245_7a0f56a6bb79783d_29.txt | There was one aspect of the discussion that took me by complete surprise.

quantumcomputing/175_40094682244c3a83_2346.txt | The ensemble method is a promising way to mitigate the overestimation issue in Q-learning, where multiple function approximators are used to estimate the action values. It is known that the estimation bias hinges heavily on the ensemble size (i.e., the number of Q-function approximators used in the target), and that de... |
