Subspace variational quantum simulator

Subspace local quantum channels

A special class of quantum channels, named subspace local (SL), are defined and investigated. The proposed definition of subspace locality of quantum channels is an attempt to answer the question of what kind of restriction should be put on a channel, if it is to act ‘locally’ with respect to two ‘locations’, when these naturally correspond to a separation of the total Hilbert space in an ortho...

Quantum Consciousness Soccer Simulator

In cognitive sciences it is not uncommon to use various games effectively. For example, in artificial intelligence, the RoboCup [14] initiative was to set up to catalyse research on the field of autonomous agent technology. In this paper, we introduce a similar soccer simulation initiative to try to investigate a model of human consciousness and a notion of reality in the form of a cognitive pr...

Quantum Variational Autoencoder

Variational autoencoders (VAEs) are powerful generative models with the salient ability to perform inference. Here, we introduce a quantum variational autoencoder (QVAE): a VAE whose latent generative process is implemented as a quantum Boltzmann machine (QBM). We show that our model can be trained end-to-end by maximizing a well-defined loss-function: a “quantum” lowerbound to a variational ap...
