Fault-tolerant structures for measurement-based quantum computation on a network

Blog Article

In this work, we introduce a method to construct fault-tolerant $ extit{measurement-based quantum computation}$ (MBQC) architectures and numerically estimate their performance over various types of networks.A possible application of such a paradigm is distributed quantum computation, where separate computing nodes work together on a fault-tolerant computation through click here entanglement.We gauge error thresholds of the architectures with an efficient stabilizer simulator to investigate the resilience against both circuit-level and network noise.We show that, for both monolithic (i.e.

, non-distributed) and distributed implementations, an architecture based on the diamond lattice may outperform the conventional cubic lattice.Moreover, the high erasure thresholds of non-cubic lattices may be exploited further in a distributed context, as their performance may be boosted through $ extit{entanglement distillation}$ by trading in entanglement success rates against erasure errors during the error-decoding process.These results highlight the significance of lattice geometry in the design iphone 13 pro max price florida of fault-tolerant measurement-based quantum computing on a network, emphasizing the potential for constructing robust and scalable distributed quantum computers.
