RushHour: A Dynamically Reconfigurable Lattice-Surgery Architecture
Nathaniel Tornow, Aleksandra Świerkowska, Peter Wegmann +1
Practical fault-tolerant quantum computing (FTQC) requires efficient lattice surgery (LS), so that large algorithms fit on resource-constrained quantum chips. Existing approaches,…
Quantum-Classical Computing via Tensor Networks
Nathaniel Tornow, Christian B. Mendl, Pramod Bhatotia
Circuit knitting offers a promising path to the scalable execution of large quantum circuits by breaking them into smaller sub-circuits whose output is recombined through classical…
Qonductor: A Cloud Orchestrator for Quantum Computing
Emmanouil Giortamis, Francisco Romão, Nathaniel Tornow +2
We describe Qonductor, a cloud orchestrator for hybrid quantum-classical applications that run on heterogeneous hybrid resources. Qonductor abstracts away the complexity of hybrid…
Scaling Quantum Computations via Gate Virtualization
Nathaniel Tornow, Emmanouil Giortamis, Pramod Bhatotia
We present the Quantum Virtual Machine (QVM), an end-to-end generic system for scalable execution of large quantum circuits with high fidelity on noisy and small quantum processors…
QOS: A Quantum Operating System
Emmanouil Giortamis, Francisco Romão, Nathaniel Tornow +1
Quantum computers face challenges due to hardware constraints, noise errors, and heterogeneity, and face fundamental design tradeoffs between key performance metrics such as \texti…
