About Quantum Technology
Quantum technologies are driving breakthroughs in computing, communication, sensing, and cryptography by leveraging the principles of quantum mechanics.
Lasers play a critical role in these systems, enabling the precise control of atoms and photons required for applications such as laser cooling and trapping, photon entanglement, quantum sensing, and Rydberg excitation.
Tunable Lasers for Quantum Technology
Radiantis products contribute to quantum innovation through three key technologies: laser cooling and trapping for ultra-cold temperatures, photon entanglement for quantum communication and computing, and Rydberg excitation for exploring atomic states with extreme sensitivity.
Laser Cooling and Trapping
Laser cooling and trapping are crucial techniques in quantum technology, allowing scientists to slow down and manipulate atoms and molecules with unprecedented precision. Laser cooling reduces particle temperatures to near absolute zero through the interaction of laser light and atomic motion. Tunable lasers spanning visible to infrared ranges enable researchers to target diverse atomic and molecular species, maximising efficiency through wavelength precision.
Photon Entanglement
Photon entanglement connects multiple photons such that one photon’s state instantaneously influences the others, regardless of distance. This property underpins quantum communication, cryptography and computing applications. Tunable lasers enhance entangled photon generation by providing precise wavelength control, enabling researchers to tailor photon energy to specific quantum systems and optimise conditions for producing high-fidelity entangled pairs.
Rydberg Excitation
Rydberg atoms are highly excited atoms with electrons in very high principal quantum number states, exhibiting extreme sensitivity to external fields. These atoms prove valuable for quantum simulations and information processing. Laser tunability across visible to infrared wavelengths ensures compatibility with various atomic species, facilitating studies of quantum entanglement and collective behaviours in Rydberg atom arrays.

“
Radiantis were very flexible with our requirements and perfectly matched to our technical needs and budget. Radiantis OPO has enabled us to carry out advanced optical characterisation of our systems across the UV, Visible and IR, and has proven to be a very reliable and easy-to-use system, delivering high and stable power and fast automated tuning across the complete spectral range. Radiantis team were very friendly and provided a professional and comprehensive user training to key researchers in my lab, which enabled us to operate the OPO successfully and reliably over many years.

The wide tuning range of our Radiantis OPO system has allowed us to access wavelength regimes that have enabled a number of nonlinear optics experiments that would otherwise not have been possible. Radiantis have been very responsive and any problems have always been dealt with swiftly, with engineers being sent over to our lab for extended visits whenever required.
