I have a master degree in thin-films interferometry, and I want to receive a Ph.D position in the area of Quantum optics. How can I assure receiving this position? What are the required skills or certificates to be accepted?
You can get a PhD position without specific knowledge of the research area. For quantum optics, commonly desired skills include:
- English language skills
- Advanced mathematical skills, including statistics
- Broad education in physics
- Experience conducting research
You do not need a "certificate." You will need a masters degree (which can substitute for a bachelors degree in countries that require a bachelors degree).
