Release-free phononic crystal with strong microwave coupling
Joey Frey, Paul Burger, Trond Hjerpekjøn Haug +2
Phonons hold promise for storing and transferring quantum information, including in mechanically-mediated quantum interconnects between superconducting qubits and light. Phononic c…

Optomechanical crystal in light-resilient quantum ground state
Johan Kolvik, Paul Burger, David Hambraeus +4
Interaction between light and high-frequency sound is a key area in integrated photonics, quantum and nonlinear optics, and quantum science. However, the typical suspended optomech…

Lattice surgery with Bell measurements: Modular fault-tolerant quantum computation at low entanglement cost
Trond Hjerpekjøn Haug, Timo Hillmann, Anton Frisk Kockum +1
Modular architectures are a promising approach to scaling quantum computers to fault tolerance. Small, low-noise quantum processors connected through relatively noisy quantum links…
