If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at forums@fqxi.org with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.
Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.
Can We Feel What It’s Like to Be Quantum?
Underground experiments in the heart of the Italian mountains are testing the links between consciousness and collapse theories of quantum physics.

Abstract: Quantum dots can be realized in various semiconductors, starting from GaAs, to Si to even graphene. In these systems electrons are confined in all three dimensions and behave like artifical atoms. The quantum dots have a discrete energy spectrum that is filled following Pauli’s principle and possible exchange effects. The energy spectrum of quantum dots can be investigated by transport experiments, as well as by optics. Several qubit implementations have been proposed. In this talk I will give an overview on how these quantum dots are technologically realized and what qubit implementations are possible.
