2016-12-08: Applied Physics seminar
Title: Thermotronics: toward circuits for the thermal light
Speaker: Philippe Ben-Abdallah, Laboratoire Charles Fabry, Université Paris-Saclay, Palaiseau Cedex, France
Time: 9:00-10 AM, Thur. 2016-12-08
Location: FA31, KTH-AlbaNova
Abstract: The control of electric currents in solids is at the origin of the modern electronics which have revolutionized our daily life. The diode and the transistor introduced by Braun, Bardeen and Brattain are undoubtedly the corner stones of modern information technologies. Such devices allow rectifying, switching, modulating and even amplifying the electric current. Astonishing, similar devices which would make possible the control of heat flow is not frequent at all in our current life. In this seminar I will discuss the possibility to develop, thermal analogs of these fundamental building block for controlling the flow of heat by radiation, instead of the flow of electrons. After describing the operating mode of a radiative diode and transistor we have recently introduced I will describe a mechanism of thermal bistability which is at the origin of the radiative thermal memory. Finally, the possibility to develop, contactless thermal logic gates to process heat flows with thermal photons using complex architectures will be discussed. While still in their infancy, these active devices could allow the realization of complex thermal circuits which could lead to a plethora of sophisticated applications such as active temperature control in microelectronics, smart IR image sensors, or even thermal computation with ultra-low power consumption.

Title: Quantum Error Correction
Candidate: Jonas Almlöf
Time: Friday January 29, 2016, at 14:00
Location:  Room FA32, Albanova, Roslagstullsbacken 21, KTH, Stockholm
Opponent: Prof. Jan-Åke Larsson, Linköpings Universitet
Supervisor: Prof. Gunnar Björk
Abstract: Quantum error correction is the art of protecting quantum states from the detrimental influence of the environment. I consider several different types of environments, and show how to distill meaningful figures of merit from codes adapted for these channels. These figures reflect both information and entanglement, and incorporates the choices one has to make when dealing with errors that can only be detected.
