Over the past few days, IST Austria became a meeting point for quantum technology experts during the “Frontiers of Circuit QED and Optomechanics” (FCQO18) conference. The meeting with about 110 participants addressed a wide range of topics from reservoir engineering to hybrid quantum devices to quantum error correction (press release).

The conference Frontiers of Circuit QED and Optomechanics will take place at IST Austria on Feb. 12 to 14. We aim to bring together the leading scientists in Circuit QED, Electro/Optomechanics and hybrid systems. Registration is open now and we are excited to announce the preliminary program:
Nonreciprocal circuit elements form an integral part of modern measurement and communication systems. Mathematically they require breaking of time-reversal symmetry, typically achieved using magnetic materials and more recently using the quantum Hall effect, parametric permittivity modulation or Josephson nonlinearities. We realized an in-situ reconfigurable, magnetic-free, on-chip circulator based on reservoir-engineered electromechanic interactions.

In February we are organizing a conference in Semmering, a small skiing resort close to Vienna. The topics include quantum opto- and electromechanics, circuit QED and everything in between. More details including our current list of invited speakers at https://ist.ac.at/fcqo18/invited-speakers/.
[Update: Due to a delay in the construction and renovation works at Hotel Panhans we were forced to relocate the conference to the IST Austria campus.]
We got an ERC starting grant to work on QUNNECT: A Fiber Optic Transceiver for Superconducting Qubits.
Many researchers are convinced that superconducting quantum processors will soon help solve complex problems faster, improve optimization and simulation, and boost the progress in artificial intelligence. A worldwide quantum web is the next logical step. It would not only improve communication security, it represents the key to unlock the full potential of the new quantum-computing paradigm.
Unfortunately, research in optical quantum networks and superconducting devices has progressed largely independently so far. While superconducting qubits are ideally suited for on-chip integration and fast processing, they are problematic for quantum communication. Only just now we have gained sufficient insight into low loss materials, the required fabrication technology, and the precision measurement techniques necessary to bridge the two worlds.
We will integrate silicon photonics for low-loss fiber optic communication with superconducting circuits for quantum processing on a single microchip. As intermediary transducer we will focus on two approaches: (1) quantum ground state cooled nanoscale mechanical and (2) low-loss electro-optic nonlinear circuit elements. One novelty of our approach is the tight on-chip integration which will be the key for realizing a low-loss and high-bandwidth transceiver, for preparing remote entanglement of superconducting qubits, and for extending the range of current fiber optic quantum networks.
NOMIS is a private Swiss foundation supporting insight-driven scientific endeavors across all disciplines. Together with the Katsaros group at IST Austria, NOMIS supports us to work on Hybrid Semiconductor — Superconductor Quantum Devices.
