Constant-depth global shadow estimation
Qingyue Zhang, Zhou You, Dayue Qin +3
Reliable and scalable readout strategies are essential for quantum technologies. As quantum processors grow, extracting useful information must remain feasible without measurement…
Quantum low-density lattice codes
Timo Hillmann, Jens Eisert, Francesco Arzani
Gottesman-Kitaev-Preskill (GKP) codes provide a family of promising schemes for encoding discrete quantum information (qudits) into infinite-dimensional bosonic modes based on math…
Witness expansion: A unified framework for analytical and measurable mixed-state resource detection
Yifan Tang, Chengkai Zhu, Yuzhen Zhang +6
Quantum information science aims to harness different kinds of quantum resources to accomplish specific information-processing tasks. These resources also play an increasingly impo…
Nearest-neighbour gates are all you need: High-rate quantum low-density parity-check codes on a planar grid
Boren Gu, Tamas Noszko, Vincent Steffan +4
High-performance quantum low-density parity-check codes promise substantial reductions in the overhead of fault-tolerant quantum computation, but most constructions require long-ra…
