Abstract(in English) As a mathematical model of associative memories, the Hopfield model was well-established and a lot of studies to reveal the pattern-recalling process have been done by various different approaches. As well-known, a single neuron is itself an uncertain, noisy unit with a finite non-negligible error in the input-output relation. To model the situation, a kind of 'heat-bath' that surrounds the neurons is introduced. Several studies concerning the recalling processes of the Hopfield model governed by the Glauber-dynamics at the finite temperature were already reported. However, we might extend the 'thermal noise' to the quantum-mechanical variant. In this talk, in terms of the stochastic process of quantum-mechanical Markov chain Monte Carlo method (the quantum MCMC), we analytically derive macroscopically deterministic equations of order parameters such as 'overlap' in a quantum-mechanical variant of the Hopfield neural networks. For the case of non-extensive number of embedded patterns with asymmetric Hebbian connections, we evaluate the recalling processes for one of the built-in patterns under the influence of quantum-mechanical noise.
