Product Family Description

  • Ideal for Trapped-Ion and Neutral Atom Applications
  • Range of Application-Specific Wavelengths from UV to NIR
  • 12.7 and 25.4mm Diameters for Easy Integration

Half Waveplates for Quantum Computing are ideal for the manipulation of polarization states in trapped ion, linear optical, and neutral atom quantum computing, as well as quantum cryptography applications. These waveplates are available in a range of commonly-used, application-specific wavelengths across the UV to NIR spectrum, and offer a retardance of λ/2 and a retardance accuracy of λ/200. Depending on wavelength, these waveplates feature either a first or zero-order construction for a low temperature-sensitivity, and are AR-coated for maximum transmission at the design wavelength to ensure optimal performance with low light signals. Half Waveplates for Quantum Computing are housed in a black, anodized aluminum mount and are available in both a 1’’ and more compact ½’’ size for easy integration into space sensitive systems.
