Towards experimental classical verification of quantum computation

2024 · Quantum Science and Technology

Abstract With today’s quantum processors venturing into regimes beyond the capabilities of classical devices, we face the challenge to verify that these devices perform as intended, even when we cannot check their results on classical …

Propagation of errors and quantitative quantum simulation with quantum advantage

2022 · arXiv (Cornell University)

The rapid development in hardware for quantum computing and simulation has led to much interest in problems where these devices can exceed the capabilities of existing classical computers and known methods. Approaching this for problems …

Dark Spin-Cat States as Biased Qubits

2025 · Physical Review Letters

We present a biased atomic qubit, universally implementable across all atomic platforms, encoded as a "spin cat" within ground state Zeeman levels. The key characteristic of our configuration is the coupling of the ground state …
