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…
Heralding entangled optical photons from a microwave quantum processor
Trond Hjerpekjøn Haug, Anton Frisk Kockum, Raphaël Van Laer
Exploiting the strengths of different quantum hardware components may enhance the capabilities of emerging quantum processors. Here, we propose and analyze a quantum architecture t…
