Lab-space

The Quantum Cloud Labs are located in the basement of the Earth Science building on the University of Calgary main campus. The QCloudLabs will soon be joined in this location by Paul Barclay’s Quantum Nano-Photonics Lab and Shabir Barzanjeh’s Integrated Hybrid Quantum Circuits Lab. The Quantum Cloud Lab is consists of an collaboration and electronics workshop area and three separate neighboring research labs. In addition, as part of the CFI QNET grant a lab-space is being renovated across from the existing Quantum Cloud Lab.
