Stroboscopic Stabilization of Cat Qubits
Timo Hillmann, Franco Nori, Fernando QuijandrÃa
Dissipatively stabilized cat qubits provide a promising route toward fault-tolerant quantum computation, exhibiting exponential suppression of bit-flip errors with increasing phase…
High-threshold, low-overhead and single-shot decodable fault-tolerant quantum memory
Thomas R. Scruby, Timo Hillmann, Joschka Roffe
We present a new family of quantum low-density parity-check codes, which we call radial codes, obtained from the lifted product of a specific subset of classical quasi-cyclic codes…
Single-shot and measurement-based quantum error correction via fault complexes
Timo Hillmann, Guillaume Dauphinais, Ilan Tzitrin +1
Photonics provides a viable path to a scalable fault-tolerant quantum computer. The natural framework for this platform is measurement-based quantum computation, where fault-tolera…
Linear-optical quantum computation with arbitrary error-correcting codes
Blayney W. Walshe, Ben Q. Baragiola, Hugo Ferretti +11
High-rate quantum error correcting codes mitigate the imposing scale of fault-tolerant quantum computers but require efficient generation of non-local, many-body entanglement. We p…
