Quantum computing is a form of computation that uses quantum-mechanical phenomena, such as superposition and entanglement, to process information with quantum bits (qubits), allowing certain problems to be solved more efficiently than with classical computers. Many quantum computing platforms rely on lasers to cool, trap, and manipulate qubits, particularly in trapped-ion systems. In these systems, spectroscopy plays a critical role by precisely measuring and controlling laser properties such as intensity, alignment, and polarization through observation of laser-induced energy shifts in the ions.
Trapped-ion quantum computers frequently use Ytterbium-171, Calcium-40 or Strontium-88. Neutral-atom quantum computers utilize optical tweezers and lattices which typically use Rubidium-87 and Cesium-133, which is also used for Rydberg excitation. Solid-state qubits use green lasers for initialization and readout of NV centers in diamond.
Spectroscopy can be used to characterize these lasers for wavelength accuracy and even power measurement. Below are some of the common spectrometer configurations for these lasers.
Because of their compact size and rugged design for field deployment, quantum sensors often rely on vertical cavity surface-emitting lasers (VCSELs) instead of traditional lasers. Spectroscopy plays a key role here, allowing researchers to precisely characterize VCSELs, measuring their power and wavelength accuracy to unlock their full potential in quantum applications. In addition, Avantes spectrometers may also be integrated into quality control systems during and after manufacturing.
is one of Avantes’ newest spectrometers, about the size of a deck of cards. It runs on USB power and communication, supports wavelengths from 200–1150 nm, and is available in 2048 or 4096 pixel configurations. Despite its compact size, it offers integration times as fast as 9 µs and data transfer speeds of 0.36 ms per scan.
It also features Avantes’ replaceable slit technology, allowing users to easily change slit sizes to suit different applications.
More recently Avantes released a new version of the Nexos known as the NIR enhanced model (AvaSpec-NXS2048/4096CLIR) which has superior quantum efficiency in the near infrared.
