Quantum

As atomic quantum computing and sensing demand higher operational fidelities, precise lasers are essential, maintaining fractional linewidth and frequency instability below a few parts in 100 trillion (~5×10-14). Ultra-low-expansion (ULE) cavity-stabilized lasers meet linewidth requirements but drift over time affects frequency stability. Traditional reliance on computing/sensing atoms for reference leads to downtime. We propose a dual-reference approach, where cavity-stabilized lasers sync with Vescent’s acetylene optical clock (LTS), reducing reliance on atomic corrections.
