Petrov Seminar
(or back to the Physics Seminars page)
- What? Multi-spatial-mode squeezed light for direct quantum imaging
- Who? Plamen Petrov – web & mail.
- Where? MA112
- When? Wed 17th Oct, 13:00–15:00
- Why? Our first contact with our big neighbour, the University of Birmingham. Plamen has overlapping interests with ours in Wolverhampton and will let us know of his activities there.
- How? The format of these talks is one hour: 15min all-public intro, 30min talk, 15min questions.
- Chair: Fabrice Laussy
- Stool: Jac Chadwick (L5)
- This is a student introduction, drafted by Jac:
- Plamen Petrov's research involves the manipulation of light in such a manner that it is put into a so-called Squeezed State. This state can be obtained if the light's electric field strength ε for some phases θ has a quantum uncertainty smaller than that of a coherent state. A coherent state is a specific quantum state of the quantum harmonic oscillator. The terms squeezing thus refers to a reduced quantum uncertainty, i.e. the squeezed state must also have phases at which the electric field uncertainty is larger than that of a coherent state. In other words, the light is anti-squeezed.
