Nano-photonics and Optics Seminar

Quantum Physics Seminar:"Quantum control of nano-mechanical oscillators"

Danciger B building, Seminar room
Sun, 08/12/2019 - 12:00 to 13:30

Lecturer:  Shomroni Itay  

Within the emerging field of Quantum Optomechanics, it has become possible in
recent years to establish a quantum interface between light and the motion of an
engineered mechanical oscillator, and to observe such effects as motional
sideband asymmetry, radiation pressure shot noise, and ponderomotive squeezing.
These achievements are now being extended towards applications and fundamental
research. The possibility to manipulate motion at the quantum level opens new

Quantum Physics Seminar:"Spectroscopy with quantum sensors"

Danciger B building, Seminar room
Thu, 25/07/2019 - 12:00 to 13:30

Lecturer: Tuvia Gefen
The problem of quantum spectroscopy, namely reconstruction of the frequency components of time dependent Hamiltonian,
is of great interest to chemical analysis, nano scale NMR and frequency standards. In this talk I will address two (basic) questions in this field: what is the speed/precision limit in estimating a single frequency and how well can we resolve two close frequencies.

Nanophotonics and Optics Seminar:"NP-complete Problems and Physics"

Location: Levin building, Lecture Hall No. 8 , Safra Campus
Tue, 11/06/2019 - 16:00 to 19:00

Lecturer: Prof.Scott Aaronson, University of Texas
One of the most basic questions at the intersection of computer science and physics is: can NP-complete problems be efficiently solved using the resources of the physical world? I'll survey the status of this question in 2019, touching on the P vs. NP problem; analog

Special Quantum Seminar:"Non-equilibrium Phases of Matter"

Rothberg auditorium (CS&Engineering building), Safra Campus.
Sun, 12/05/2019 - 16:00 to 18:30

Lecturer: Prof. Norman Yao (Berkeley)
Non-equilibrium systems can exhibit phenomena fundamentally richer than their static counterparts. For example, certain phases of matter that are provably forbidden in equilibrium, such as quantum time crystals, have recently found new life in out-of-equilibrium systems. In this talk, I will begin by introducing the broad landscape of periodically driven (Floquet) quantum matter.

Nanophotonics and Optics Seminar:"Security of practical quantum cryptography: know your enemy"

Danciger B building, Seminar room
Sun, 31/03/2019 - 14:00 to 15:30

Lecturer: Charles Lim Ci Wen Abstract: The grand promise of quantum cryptography is that one can secure information a lot better than conventional methods. One prime example is quantum key distribution, which promises complete security against any adversary if the secret key is transmitted using quantum communication. In other words, you do not need to know your enemy. In this talk, I will present the current results in quantum cryptography and argue that it is still necessary to “know your enemy”, especially if we want to make the technology practical
