Physics, from neutrinos to qubits

I'm Sameed, a physics master's student at LMU Munich. I studied engineering physics at IIT Hyderabad, where I worked on neutrino oscillations and on JWST data. Now I'm moving into quantum computing.

|0⟩
|1⟩

Drag the sphere to turn it. Gates rotate the state. Measuring collapses it to |0⟩ or |1⟩ with the probabilities shown.

Work

Two research projects from my time at IIT Hyderabad: one in particle physics, one in astronomical data.

Neutrino oscillations and DUNE

A muon neutrino leaves Fermilab and, 1,300 km later in South Dakota, may be detected as an electron neutrino. I computed these oscillation probabilities for neutrinos and antineutrinos, with and without matter effects, and looked at how non-standard interactions change the picture.

Calibrating JWST data

Every JWST image starts as a stack of raw detector reads. I worked with the official calibration pipeline and the MIRAGE simulator, and followed what each detector-level step does to the signal.

About

I'm a first-year master's student in physics at LMU Munich. High-energy physics and quantum mechanics are what pulled me into the subject, and I'm now taking courses on how quantum principles can be used to build the next generation of computers.

Before Munich I did my B.Tech in Engineering Physics at IIT Hyderabad. That is where I met detector physics, neutrinos and JWST data, and where I learned to balance research, coursework and campus life, with plenty of canteen chai and late-night hostel conversations along the way.

I had planned to do a PhD in the USA. Instead I'm in Munich, one of the world's hubs for quantum computing, and I plan to use my time here to move my career fully into that field.

Path

  1. LMU Munich, M.Sc. Physics

    First year. Courses on quantum computing, with the aim of working in the field.

  2. IIT Hyderabad, B.Tech Engineering Physics

    Where high-energy physics, quantum mechanics and detector physics took hold.

  3. Research projects

    Neutrino oscillations and DUNE, and the JWST pipeline with MIRAGE, under the guidance of Prof. Narendra Sahu and Prof. Mayukh Pahari.

  4. Cepheid, the astronomy club

    Core member. Helped organise a workshop on planetary data analysis, where participants processed raw telescope data. Also took part in a guest lecture on JWST by Prof. Mark McCaughrean (ESA) at the Birla Planetarium in Hyderabad.
