High-Performance Spin-State Memory for Telecom Quantum Information Applications
feeds.aps.org · By James Stuart, Kieran Smith, Morgan Hedges, Rose Ahlefeldt & Matthew Sellars ·
The Brief
- A PRX Quantum paper by Stuart, Smith, Hedges, Ahlefeldt and Sellars reports an erbium quantum memory with a record classical efficiency.
- The memory stores spin states across multiple temporal modes.
- The work targets telecom-wavelength quantum information applications.
Why it matters
Erbium emits and stores light at telecom wavelengths, so memories that work at these wavelengths could fit into existing fiber-optic infrastructure for quantum networks.
