Dear Colleague,

Please join us for the symposium QT07 on Atomic and Molecular Quantum Systems and Defect Engineering for Quantum Technologies at the 2022 MRS Spring Meeting, May 8-13, 2022, Honolulu, Hawaii (https://www.mrs.org/meetings-events/spring-meetings-exhibits/2022-mrs-spring-meeting/call-for-papers/detail/2022_mrs_spring_meeting/qt07/Symposium_QT07) by submitting an abstract here:

Single atom impurities and point defects in solid and molecular semiconductors and insulators have been observed to be excellent quantum systems that behave as qubits or single photon emitters. They can have long lived spin degrees of freedom suitable for quantum information processing, optical transitions that allow for coupling to photons, and promise to push quantum technologies beyond cryogenic environments. However, the intrinsic fragility of quantum states poses a major materials science challenge and building a device that utilizes quantum states requires attention to decoherence-causing defects. Enhanced understanding of defect measurements, manipulation, and modeling is essential but still lacking: Being able to control defects and impurities at the single emitter level and, or even knowing what the defect is, creates challenges that need to be addressed before significant progress can be made, motivating this symposium.

We have an exciting set of (tentative) invited speakers:

• Igor Aharonovich (University of Technology Sydney, Australia)
• David Awschalom (The University of Chicago, USA)
• Nathalie de Leon (Princeton University, USA)
• Jennifer Dionne (Stanford University, USA)
• Sudipta Dubey (Indian Institute of Technology Kanpur, India)
• Danna Freedman (Northwestern University, USA)
• Kai-Mei Fu (University of Washington, USA)
• Adam Gali (Wigner Fizikai Kutatóközpont, Hungary)
• Giulia Galli (The University of Chicago, USA)
• Weibo Gao (Nanyang Technological University, Singapore)
• Andreas Heinrich (Center for Quantum Nanoscience, Republic of Korea)
• Stephen Jesse (Oak Ridge National Laboratory, USA)
• Ute Kaiser (Universität Ulm, Germany)
• Prineha Narang (Harvard University, USA)
• Kasturi Saha (Indian Institute of Technology Bombay, India)
• Michelle Simmons (University of New South Wales, Australia)
• Nick Vamivakas (University of Rochester, USA)
• Chris G. Van de Walle (University of California, Santa Barbara, USA)

The symposium will cover topics including:

• Materials synthesis and characterization
• Semiconductors, insulators, wide-band-gap materials
• Low-dimensional materials
• Computational and theoretical modeling
• Defect manipulation
• Hybrid quantum devices
• Identification and control of sources of decoherence
• Characterization and modeling of qubits and single-photon emitters

Looking forward to seeing many of you in Hawaii! On behalf of the organizers,
