Departamento de Física promove colóquio na sexta-feira (3) sobre tecnologias quânticas híbridas

Convidado é o professor Vlatko Vedral, do DF da Universidade de Oxford e do Centro de Tecnologias Quânticas da Universidade Nacional de Singapura

O Departamento de Física da UFPE promoverá, nesta sexta-feira (3), às 16h, um colóquio (webinar) acerca de tecnologias quânticas híbridas. A conversa contará com a participação do professor e físico Vlatko Vedral, do Departamento de Física da Universidade de Oxford e do Centro de Tecnologias Quânticas da Universidade Nacional de Singapura.

O evento ocorrerá exclusivamente de modo virtual, através do Google Meet. Vale ressaltar que aqueles interessados em assistir ao colóquio devem entrar na sala utilizando o email institucional ( e com o microfone desligado.


Many macroscopic phenomena rely on the laws of quantum physics. The solid state physics, for instance, started with the realization that both electrons and vibrations have to be treated quantum mechanically to even begin to be able to understand the thermodynamical behavior of many-body systems. A growing body of evidence now suggests that living systems too could be utilising quantum coherence, superpositions, and even, in some cases, quantum entanglement to perform some tasks with higher efficiency. However, it is an exciting open question to what degree quantum effects can be maintained and controlled at the macroscopic level. This is interesting not just for our quest to realise scalable quantum computers, but also for engineering special-purpose programmable nano-machines.

I will explain the basics of witnessing entanglement and I will put this into the context of our present understanding of macroscopic quantum phenomena. I will then present the single molecule spectroscopy experiments we are currently undertaking in our laboratory to obtain a better understanding of quantum effects in complex (bio)molecules. This will include our observation of the vacuum Rabi splitting in a living bacterium strongly coupled with the electromagnetic field. I will then talk about the latest experiments involving a single tardigrade coupled to a superconducting quantum bit and interacting with another superconducting bit. This will lead me to speculate on the scalability of such experiments and the validity of quantum physics in the macro domain. Will quantum physics ultimately be superseded, or will it prove to be a universal description of all the known phenomena?
