Postdoc Researcher

Postdoc Researcher

Postdoc position in on-chip color center spectroscopy at QuTech.

Job Description

Are you motivated to explore the qubits that power the quantum information processing machines of the future? Do you want to embed qubits in scalable systems and help bring quantum technology to real-world applications? We are seeking a postdoctoral researcher to work at the interface of color center physics and integrated photonics!

Color centers have proven to be one of the most fruitful platforms in the quantum information era, enabling breakthroughs such as memory-enhanced quantum communication, entanglement-based quantum networks, long-term quantum information storage, and complex quantum simulations. While these demonstrations point to a wide range of applications, critical challenges regarding color center physics and their large-scale integration into systems remain untackled.

As a postdoc in the Errando-Herranz's group, you will tackle these challenges by conducting research on spectroscopy of color centers, with a focus on silicon and diamond hosts. Your will focus on device design and characterization, investigating the complex physics of color centers, and developing technologies based on integrated photonic circuits for quantum applications.

You will co-lead a team of talented PhD students within the ERC Starting Grant DISQOVER and other EU projects, collaborating with top European and international research groups. You will also have full access to the group's state-of-the-art measurement setups for magneto-optic spectroscopy at room and cryogenic temperatures down to 40 mK.

Requirements

• PhD degree in physics, electrical or mechanical engineering, or a related field.
• Strong experimental skills, demonstrated through publications in the fields of spectroscopy, quantum emitters, or quantum integrated photonics.
• Excellent written and oral communication skills in English.
• Proven independence, self-drive, and experience in supervising students.
• Collaborative, team player attitude.

Will make you stand out:

• Expertise in color center or atomic physics research.
• Experience with cryogenic measurements.
