QuTech

Outlined a staged vision for building the quantum internet. Useful for ecosystem mapping of quantum networking companies and public infrastructure initiatives.

A 21 August 2026 arXiv preprint compares classical and non-classical photon states for experiments seeking QED vacuum non-linearity, including PVLAS and all-optical four-wave-mixing configurations.

A 21 August 2026 arXiv preprint develops bounds on virtual-distillation success probability, framing the error-mitigation method as a spectral filter and deriving limits from a Slepian concentration operator.

An updated 20 August 2026 arXiv preprint presents fermionic quantum-machine-learning circuit architectures intended to balance trainability, expressivity, classical-simulation hardness, and gradient-evaluation cost.

A new arXiv theory paper studies how measurement feedback and correlated records shape work statistics in a quantum information engine, including a coherence-transition interference contribution.

A new arXiv paper evaluates quantum-jump descriptions of current fluctuations in non-additive open quantum systems and identifies conditions under which imperfect jump detection recovers Landauer-Büttiker results.

Capital, company, research, and policy signals show neutral-atom hardware, quantum infrastructure software, university programs, and government funding remaining the clearest market activity clusters.
