Postdoctoral Scholar, Quantum Memories with Vacancies in Diamond (Calgary)

Description

Postdoctoral Scholar position

Area: Quantum memories with vacancies in diamond

Duration: 1 year with possibility of extension up to 4 years (based on yearly reviews)

Start date: On or before January 2, 2026

Salary: $65,000 CAD per year plus employer benefits premiums, with additional $5,000 CAD research/travel allowance

The Department of Physics and Astronomy in the Faculty of Science at the University of Calgary invites applications for a Postdoctoral Associate in Quantum memories with vacancies in diamond.

The position is part of a pioneering, international, dual-lab initiative including UCalgary and the Raman Research Institute in India,



creating a platform of collaboration and exchange for advancing quantum communication, integrated photonic quantum computing, quantum sensing, precision tests of quantum mechanics, and the development of novel quantum-optical interfaces.

Job Description:

Under her Canada Excellence Research Chair in photonic quantum science and technologies, Dr. Urbasi Sinha is setting up a state-of-the-art quantum optics lab that will work on different aspects of quantum technologies using photons. It will emphasize strong synergy between application-driven research, which addresses immediate needs, and foundational research, which enables the technologies of the future.

As a part of this initiative, the successful candidate will develop and conduct quantum memories research with vacancies in diamond, especially nanofabrication experiments related to nitrogen, silicon and/or other vacancies in diamond. They will receive a $5,000 CAD research and travel allowance to support such requirements, subject to approval by the Principal Investigator.

Key Responsibilities:





- Design and implementation of experiments to develop on-chip quantum memories using diamond vacancy centres (NV, SiV, or related defects).
- Operation, optimization, and maintenance of cryogenic optical setups, including confocal microscopy and low-temperature photonics platforms.
- Development and testing of memory storage protocols, including optical and spin-based approaches (e.g., Raman, EIT, AFC, spin-echo).
- Integration of solid-state emitters with photonic chips, involving nanofabrication, device design, and optical/electrical interfacing.
- Characterization of coherence properties (spin¿photon coupling, dephasing times, memory lifetimes) and implementation of strategies to extend them.
- Collaboration with cleanroom facilities and fabrication partners for chip-scale device development.
- Coordination with national and international project partners, including periodic travel for joint experiments and reviews.




- Mentorship of graduate and undergraduate students in experimental methods, analysis, and quantum memory concepts.
- Preparation of manuscripts and presentations for leading journals and conferences in quantum technologies.
- Regular reporting to internal and external stakeholders, including contributions to project deliverables under national and international collaborations.
- Contribution to the strategic growth of the quantum memories programme, by identifying new storage schemes, integration approaches, and collaborative opportunities.
- Active participation in lab safety, maintenance, and best-practice development, especially in cryogenics and nanofabrication.

Qualifications

Applicants should hold a Ph.D. in Physics, Electrical Engineering, or a closely related field, with demonstrated expertise in experimental quantum science or engineering.



A strong interest in interdisciplinary research and innovation should be clearly expressed in the application.

Essential

- Strong hands-on experience in experimental solid-state quantum optics, particularly with NV/SiV (or other colour centres) in diamond.
- Proficiency with cryogenic systems (closed-cycle cryostats, cryogenic confocal setups) and optical access at low temperatures.
- Demonstrated expertise in optical addressing and readout of spin states in diamond vacancies.
- Experience with single-photon generation, collection, and characterization from solid-state emitters.
- Knowledge of quantum memory protocols (e.g. DLCZ-type, Raman, spin-photon interfaces) and their experimental implementation.
- Strong background in integrated photonics: coupling emitters to waveguides, cavities, or photonic crystal structures.




- Proficiency in cleanroom nanofabrication techniques (lithography, etching, thin-film deposition) relevant to on-chip devices.
- Solid programming skills for experiment control and data analysis (Python, MATLAB, LabVIEW).
- Ability to design, align, and calibrate complex cryogenic optical setups independently.
- Flexibility to travel nationally and internationally for experiments and collaborations.
- Excellent communication skills and willingness to collaborate in an interdisciplinary, international environment.

Desirable

- Experience with coherent optical storage protocols (e.g., spin-echo, EIT, AFC, or other quantum memory techniques).
- Knowledge of microwave and RF control techniques for spin manipulation in colour centres.
- Familiarity with strain, electric-field, and magnetic-field tuning of colour centres in diamond.




- Prior work on hybrid quantum systems, e.g., coupling diamond defects to cavities, waveguides, or nanomechanical resonators.
- Understanding of error sources, decoherence mechanisms, and strategies for prolonging coherence times.
- Familiarity with chip-scale integration of emitters (pick-and-place, bonding, or wafer-scale fabrication workflows).
- Experience with quantum optics simulations (e.g., QuTiP, cluster-state memory simulations).
- Strong publication record in diamond quantum technologies, solid-state quantum optics, or quantum memories.
- Track record of mentoring students and contributing to collaborative projects.
