The distribution and geochemistry of these ... |
quantumcomputing/10115_89d726a9f93da8d2_46.txt | And so we waited: four optimized hybrids somewhere past the threshold of mere humanity, one extinct predator who'd opted to command us instead of eating us alive. We waited for *Rorschach* to come back around the bend. The probe fell smoothly around the well, an ambassador to the unwillingor, if the Gang was right, ma... |
quantumcomputing/3960_f86f793cf9e31867_37.txt | The scheduling of the DSN is a highly complex task that relies on both human interventions and automated solutions. It consists of three successive phases and can take up to a few months. Since it involves a synergy of human planning and computational resources, several efforts have been made to lower the computational... |
quantumcomputing/22087_69ca229ec5299de3_1256.txt | Abstract: Certain materials form geometric structures called "grains," which means that one has distinct volumes filled with the same semi-solid material but not mixing. This can happen with semi-molten copper and something like this can also happen with liquid crystals (which are used in some calculator display screen... |
quantumcomputing/27984_723fd0fbfe5d7a11_431.txt | There are various gate sets that can be used to describe a quantum computation. A particularly popular gate set in the literature on quantum computing consists of arbitrary single-qubit gates and 2-qubit CNOT gates. A CNOT gate is however not always the natural multi-qubit interaction that can be implemented on a given... |

quantumcomputing/9073_a8a638dc956ff973_137.txt | Another quantum state preparation method was presented in ref. 410 based on reinforcement learning which is a machine learning training architecture framework that finds an optimal solution to a problem based on the principle of rewarding the desired actions and penalizing the negative actions. The authors made a compa... |

quantumcomputing/14994_2ed2d1df17fe28a3_365.txt | Let’s say we have a finite universe simulated with (which as far as I can tell is the same thing as “running on”) computational class X. Now let’s have a finite system within that universe that is a physical realization of computational class Y. What must be true about the relationship between X and Y in order for Y to... |

quantumcomputing/34011_a5801def072ec91c_190.txt | As always, determining what a concealed contradiction is, and what we know to be true versus what we merely believe to be true, is a challenge. As Stebbing says, we all have beliefs that are “cherished”. They are sometimes the things our parents believed, so we grew up believing them too, or sometimes the things associ... |
quantumcomputing/22108_db9c0f2f4b6f960d_2812.txt | A ternary gauge field theory is explicitly constructed based on a totally antisymmetric ternary-bracket structure associated with a 3-Lie algebra. It is shown that the ternary infinitesimal gauge transformations do obey the key closure relations [δ1, δ2] = δ3. Invariant actions for the 3-Lie algebra-valued gauge fields... |
quantumcomputing/1226_4503ad1eb65e514b_346.txt | We are now equipped with a method for accurately rescaling the signal to arbitrary model parameters, with the only potential source of errors being the interpolation in mass and lifetime. In a background-free experiment, this would be fully sufficient for computing the sensitivity or limits. For the projected “discover... |

quantumcomputing/17894_afb95353be58d856_87.txt | We present a real-time stochastic approach based on density matrix quantum Monte Carlo (QMC) to simulate the dynamics of open quantum systems coupled to infinite-dimensional quantum baths. This approach stochastically samples the time-dependent density matrix of a many-body system evolving under a Markovian or non-Mark... |

quantumcomputing/6436_723fd0fbfe5d7a11_216.txt | ZX calculus is a graphical language for reasoning about linear maps. Maps are represented as graphs, and reasoning amounts to graph rewrites. The main applications of ZX calculus are in quantum computation. We train small transformers to simplify ZX graphs, i.e. perform resource optimisation of quantum circuits. Prelim... |
quantumcomputing/34011_16096e4fa9a74541_28.txt | Although mapping constraints as penalizations might be sufficient for their enforcement, this method requires finding these penalization factors, which might lead to challenging numerical issues for both classical and quantum methods. A way of leveraging these Ising solvers, potentially quantum, while enforcing the con... |
