4. Description: Laboratory, optical and precision equipments (excl. glasses). The estimated value of this requirement is £110,000 exclusive of VAT.

The National Quantum Computing Centre aims at building quantum computers which will be made available to end users. Among others, one of the hardware platforms we are developing is based on trapped ions. In trapped ions quantum computing, lasers are used to interact with the internal states of a single and multiple ions. Depending on the chosen ion species and internal states, specific laser frequencies are used. The precise wavelength/frequency of these lasers needs to be calibrated to a high degree to allow them to interact with the ions.
To this end, a high accuracy Wavelength Measurement System is needed which can measure the frequency of a laser with an absolute frequency uncertainty of 20 MHz or below (lower is better).
