The global quantum internet will require long-lived, telecommunications band photon-matter interfaces manufactured at scale. Preliminary quantum networks based upon photon-matter interfaces which meet a subset of these demands are encouraging efforts to identify new high-performance alternatives. Silicon is an ideal host for commercial-scale solid-state quantum technologies. It is already an advanced platform within the global integrated photonics and microelectronics industries, as well as host to record-setting long-lived spin qubits. Despite the overwhelming potential of the silicon quantum platform, the optical detection of individually addressable photon-spin interfaces in silicon has remained elusive. In this work we produce tens of thousands of individually addressable ` $T$ centre' photon-spin qubits in integrated silicon photonic structures, and characterize their spin-dependent telecommunications-band optical transitions. These results unlock immediate opportunities to construct silicon-integrated, telecommunications-band quantum information networks.The global quantum internet will require long-lived, telecommunications band photon-matter interfaces manufactured at scale.

A New Model of Consciousness as a Quantum Field

Antonio Manzalini

The article proposes a new model of consciousness of living organisms, based on an extension of the de Broglie-Bohm theory, which is also meeting the principles of the Quantum Field Theory. In particular, the article starts from the consideration that living organisms are similar to open systems, operating far from the thermodynamic equilibrium: in fact, they are subjected to continuous internal flows and exchanges of energy, matter and information with the surrounding environments. On a deeper physical level, however, these exchanges are mediated by quantum wave oscillations and interactions, so that it is argued that living organisms are even operating far from quantum equilibrium. Therefore, leveraging on a prior art arguing that quantum theory might be a special case of a much wider physics, where systems are far from quantum equilibrium, the article proposes a wider perspective of the de Broglie-Bohm theory for modeling consciousness. Consciousness is modelled as a special quantum wave field whose associated potential is elaborated as active information by living organism and accounts, with different complexity levels, for consciousness phenomena in life. Moreover, the article proposes that the form or curvature of the consciousness wave field can be expressed in terms of Nambu Goldstone bosons condensations (as described in Quantum Field Theory) associated to symmetry breaking phenomena in living organisms.The article proposes a new model of consciousness of living organisms, based on an extension of the de Broglie-Bohm theory, which is also meeting the principles of the Quantum Field Theory.
